Description

The present invention relates to a rope connected to a net or a seat, an endless winch for moving a rope used for a gondola, and a rope moving method using the endless winch.

Conventionally, for example, an endless winch used to move a rope connected to a net or a sheet (hereinafter referred to as a generic name such as a metal or resin wire rope) (hereinafter, the rope is taken in from one side of the winch and the other side) The general structure of the winch used for taking out and moving to the main body) is rotatably supported by the winch body and connected to a drive source (including a power supply motor or a manual handle). A driving shaft to be driven, a winding drum attached to the driving shaft and having a circular groove formed along the outer peripheral surface thereof, and rotatably supported by the winch body in the vicinity of the winding drum; A pair of guide rollers for guiding and assisting in taking in the rope into the groove and taking out the rope from the groove, and along the outer side of the groove with the guide roller side as both end sides. A moving roller body which is attached to be wound around and is formed by rotatably connecting a plurality of rollers, and an elastic body such as a spring connected to end rollers on both ends of the moving roller body; It is composed of

When moving a rope connected to a net or the like using the endless winch, first, the drive shaft is driven to rotate using a drive source and the winding drum is rotated via one guide roller. A rope is introduced into the distal end side of the moving roller body, and a desired amount of the moving roller body is adjusted along the groove by using an urging force of an elastic body connected to the moving roller body and rotation of a winding drum. After moving and starting from the moved position, the rope is sequentially taken in and moved while pushing the rope toward the groove at the end roller portion on the tip side, and then the rope is pushed into the groove while pushing the rope toward the groove with the moving roller body. Along the direction of rotation along the direction of rotation, using the urging force of the elastic body connected to the other side of the moving roller body, the other end roller is pressed against the groove side and the rope is sequentially separated from the groove, The winch body through the guide roller Ri is taken out to move.

Since the moving roller body used for the endless winch is composed of one piece along the groove on the take-in side from the rope take-in side, the end roller on the take-in side of the rope groove and the groove from the groove are arranged. When the movement amount along the groove with the end roller on the rope take-out side is interlocked and the movement amount of the end roller portion on the take-in side is large, the end roller moves greatly toward the elastic body side on the take-out side, and the If the biasing force by the elastic body is weak and the pressing force by the end roller to the groove side is insufficient, and conversely the movement amount of the end roller on the intake side is small, the movement of the end roller on the take-out side is small, The pressing force to the groove by the partial roller is too strong. For this reason, there is a drawback that the rope cannot be flexibly applied to the tension applied to the rope, and the rope cannot be smoothly moved.

Therefore, a moving roller body in which the moving roller body is divided into two at the central portion has been considered. The specific structure of the two-divided moving roller body is such that the end roller on the tip end side (guide roller side) of each of the two divided moving roller bodies is directly connected to the guide roller or the support shaft of the guide roller. And connecting each of the moving roller bodies on the rope take-in side and the rope take-out side by pivotally supporting the end portion on the rear end side of each moving roller body on the winch body in the vicinity of the winding drum. This is a configuration in which the pressing movement toward the groove side is independently performed.

As a result, one moving roller body and the other moving roller body can be freely handled without interlocking according to the strength of the tension applied to the rope.
JP 2012-56769 A

Problems to be solved by the invention

However, the above-mentioned conventional endless winch is formed by each moving roller body divided into two parts, and corresponds to the strength of the rope tension independently. Since the rear end side of the moving roller body is pivotally supported by the winch body, the groove portion between the two pivotally supported points becomes a blank portion with respect to the pressing movement, and the winding movement along the rope groove There was a drawback that could not be performed smoothly.

In particular, when the tension is weak, the rope will loosen, etc., causing problems such as separation and loosening of the rope from the groove in the blank area, and the rope cannot be properly wound and moved along the groove. There were drawbacks.

Further, since the rear end side of each moving roller body is pivotally supported by the winch body, the end roller on the rear end side cannot move in the pivotal support direction, and is moved to the groove side by the end roller portion. There has been a drawback that the pressing movement of is insufficient.

Furthermore, when the moving roller body divided into two parts is pressed and moved along the groove, the rope should be against the strength of the tension unless the moving roller body has an equal length and a desired distance. Since it cannot press appropriately to the groove side, adjustment through the elastic body of the tip side of each moving roller body and the connecting plate is complicated.

Accordingly, the present invention can appropriately move the rope along the groove of the winding drum according to the strength of the rope tension, and can be used for an endless winch capable of smoothly and surely pressing and moving the rope. It is an object of the present invention to provide a rope moving method using the endless winch.

Means for solving the problem

An endless winch as a means for solving the above-mentioned problem is attached to a winch body so as to be freely rotatable, and a drive shaft that is rotationally driven by a drive source, and an outer peripheral surface that is attached to the drive shaft. A winding drum in which a rope is wound around the winding drum, and a winch body rotatably supported in the vicinity of the winding drum, and the rope is taken into and out of the groove side. A guide roller, and a moving roller body formed by connecting a plurality of freely rotatable rollers, the guide roller side being attached in a rotating direction along the groove of the winding drum with the guide roller side as a leading end side The rear end side of the moving roller body is directly or indirectly supported by the winch body in the vicinity of the winding drum, and the moving roller body Wherein the spirally wound elastic member for pressing the rope groove side along the groove continuously to the end roller at the end side.

The rope moving method using the endless winch as means for solving the above-mentioned problem is the rotational movement of the drive shaft rotatably attached to the winch body, as described in claim 2. One guide roller that is rotatably supported by the winch body in the vicinity of the winding drum while rotating the winding drum that is attached to the shaft and has a groove that winds the rope along the outer peripheral surface The rope is taken into the groove side via the guide roller side, and the moving roller body attached along the groove with the guide roller side as the tip side is wound in the rotational direction along the groove while pressing the rope against the groove side. In the method of moving a rope using an endless winch that is taken out from the groove through the other guide roller and moved, the front end side or the rear end side of the moving roller body is a tension applied to the rope. After adjusting the pressure according to the strength of the roller and taking it into the groove side and winding it along the groove, it is continuously provided along the groove in the rotational direction along the rear end side of the moving roller body. It is characterized in that the rope wound by the wound elastic body is taken out from the groove and moved while being pressed against the groove side with a constant force.

Effects of the invention

Next, the effects of the endless winch of the present invention and the rope moving method using the endless winch will be described.

First, an endless winch according to claim 1 is a winding drum in which a drive shaft that is rotatably attached to the winch body and a groove that is attached to the drive shaft and winds a rope along an outer peripheral surface are formed. A guide roller rotatably supported on the winch body in the vicinity of the winding drum, and a plurality of movable rollers mounted along the groove of the winding drum with the guide roller side as a leading end side. And a moving roller body formed by connecting rollers.

Since the rear end side of each moving roller body is directly or indirectly supported by the winch body in the vicinity of the winding drum, the position of the rear end side of the moving roller body is adjusted ( When the rope is guided and moved on the tip side of the moving roller body by adjusting the urging force of the elastic body connected to the moving roller body by changing the mounting position to the winch body, the moving roller The force that biases the body in the direction of rotation and the amount of movement of the end roller on the rope intake side by the desired amount in the direction of rotation of the winding drum can be adjusted to assist the guide movement toward the groove side of the rope. At the same time, the rope incorporated in the groove can be wound along the groove while being wound and pressed on the groove side by the entire moving roller body.

That is, when the tension applied to the rope is strong, the end roller on the tip side is slightly biased in order to strongly bias the end roller on the tip side of the moving roller body away from the groove side. Push the rope while moving only to the groove side and take the rope into the groove. On the other hand, when the tension applied to the rope is weak, the urging force acting on the end roller on the tip side is weak, so the end roller on the tip side moves greatly while pressing the rope against the groove side. Into the groove.

For this reason, when the tension is strong, the attaching position to the winch body on the rear end side of the moving roller body is moved in a direction away from the guide roller, and the urging force acting on the moving roller body by supporting the moving roller body is strengthened. When the tension is weak, it moves in the direction close to the guide roller and is pivotally supported to weaken the urging force acting on the moving roller body, thereby responding to the strength of the tension.

The moving roller body is provided with an elastic body wound in the rotation direction along the groove on the end roller side of the rear end side of the moving roller body. Thus, the rope pressed to the groove side can be continuously wound and pressed to the groove side with a constant pressing force by a wound elastic body without a gap.

For this reason, it is possible to freely adjust the amount of movement of the moving roller body according to the tension applied to the rope, and the winding elastic body connected to the end roller on the rear end side of the moving roller body. By continuously pressing toward the groove side, it is possible to cope with the difference in tension applied to the rope and move while reliably pressing and winding the groove side.

Moreover, since the winding elastic body is continuously provided on the rear end side of the moving roller body as described above, the distance in the length direction of the moving roller body can be freely adjusted. By adjusting the length of the roller body, it is possible to further flexibly cope with the tension applied to the rope.

Therefore, since the rope can be wound and moved by combining the moving roller body and the winding elastic body having the most appropriate and simple configuration in accordance with the strength of the tension applied to the rope, frequent maintenance work is not required.

Next, in the method of moving a rope using the endless winch according to claim 2 of the present invention, a drive shaft rotatably attached to the winch body is driven to rotate, and a winding attached to the drive shaft. In a state where the drum is rotated, the rope is formed on the outer peripheral surface of the winding drum through one guide roller and moved into the groove, and after winding along the groove, the rope is separated from the groove and the other The rope is taken out and moved through the guide roller.

When a rope is taken into the groove of the winding drum, it is taken in and wound using a moving roller body attached along the groove with the guide roller side as a tip side.

That is, the rope is introduced and moved to the groove while being guided to the groove side through one guide roller attached to the front end side of the moving roller body, and the front end side or the rear end side of the moving roller body is pressed. By adjusting (adjusting the pivoting position on the winch body and adjusting the mounting method), the moving roller body is moved in synchronism with the rotating direction using the urging force of the winding drum in the rotating direction. While adjusting the pressure of the rope to the groove side (adjustment using the synergistic effect that the rotation of the winding drum and the pressure adjustment direction of the moving roller body are the same direction), the rope is wound along the groove. .

That is, the tip side of the moving roller body is pivotally supported by the winch body via the elastic body, thereby adjusting the pressing position of the end side end roller toward the groove side (hangs on the end side end roller rope). (Movement of the position due to the strength of the tension), pressing force (biasing force to the groove side by the end roller on the tip side), and winding pressure to the groove side by the moving roller body (preventing the rope from coming off the groove) The rear end side of the moving roller body is pivotally supported on the winch body through the elastic body, so that the end roller on the front end side is pressed against the groove side by the moving roller body. The winding pressing to the groove side and the adjustment of the pressing position of the end roller on the rear end side (adjustment of the position of continuously pressing and moving to the winding elastic body) can be adjusted.

Next, the rope taken into the groove continues to the end roller portion using a wound elastic body provided along the groove continuously to the end roller on the rear end side of the moving roller body. Then, the rope can be wound and pressed to the groove side with a constant force, and the rope can be wound and moved along the groove in a stable state.

For this reason, the rope wound around the groove by the pressure adjustment by the moving roller body can be wound along the groove while being continuously pressed along the groove by the pressing by the winding elastic body.

As described above, the rope moving method using the endless winch of the present invention can move the rope smoothly by using the guiding and pressing movement of the moving roller body and the pressing by the wound elastic body. it can.

In addition, since it is pressed by the wound elastic body that is connected to the moving roller body, the guidance and pressing to the rope are always adjusted to the optimum state, and the wear of the rope is also when using a conventional endless winch. There is an advantage that it can be remarkably reduced.

Therefore, the endless winch and the rope moving method using the endless winch according to the present invention correspond to the strength of the tension applied to the rope by connecting the moving roller body and the wound elastic body. Thus, the rope can be reliably moved along the groove with the wound elastic body while adjusting the pressure of the moving roller body, and the rope can be stably moved, and frequent maintenance work is not required.

An endless winch of the present invention and a rope moving method using the endless winch will be described.

12 and 13 are flowcharts showing a rope moving method using the endless winch of the present invention.

An embodiment of an endless winch of the present invention and a rope moving method using the endless winch will be described with reference to the drawings.

An endless winch 1 according to the present invention is rotatably supported by a rectangular winch main body 2 and a substantially central portion of the winch main body 2, and is connected to a driving source (not shown including a manual type and an electric type). Thus, the drive shaft 3 that is rotationally driven, the winding drum 4 that is attached to the drive shaft 3 and is formed in a disk shape, and the winch body 2 that is attached in parallel to the winch body 2 in the vicinity of the winding drum 4 A pair of guide rollers 7A and 7B rotatably supported on the support shafts 8A and 8B and a circumferential shape of the winding drum 4 along the outer peripheral surface of the winding drum 4 are formed in a substantially V shape, and the rope 20 is wound around. And a moving roller body 6A, 6B which is divided into two along the groove 5.

End rollers 9A, 9Z on the guide rollers 7A, 7B side (hereinafter referred to as the front end side) of the two divided moving roller bodies 6A, 6B are pivotally supported by the support shafts 8A, 8B, respectively. Are connected to springs 11A and 11B as elastic means, and are connected to the other ends of the connecting plates 10A and 10B formed in a bow shape.

As a result, the connecting plates 10A and 10B press the end rollers 9A and 9Z toward the groove 5 by the biasing of the springs 11A and 11B (arrows a and z) (rotate and move around the support shafts 8A and 8B). Is biased in the direction (arrow f, arrow v).

Further, when the end rollers 9A and 9Z are pressed toward the groove by the rotational movement of the connecting plates 10A and 10B, the moving roller bodies 6A and 6B are urged toward the guide rollers 9A and 9Z, respectively. The action will work.

End rollers 9B and 9Y on the opposite side to the guide rollers 7A and 7B of the moving roller bodies 6A and 6B (hereinafter referred to as rear end sides) are wound around springs 12A and 12B as elastic means. A desired distance is maintained in the vicinity of the drum 4 and is supported on the winch body 2.

As a result, the moving roller bodies 6A and 6B are urged (arrows m and n) in the direction toward the end rollers 9B and 9Y, and always (in a state where the winding drum 4 is not rotating). The moving roller bodies 6A and 6B are biased toward the guide rollers 7A and 7B by the springs 11A and 11B of the connecting plates 10A and 10B and toward the end rollers 9B and 9Y by the springs 12A and 12B. It is positioned in a state of being equalized by the biasing of.

Between the end rollers 9B and 9Y of each of the moving roller bodies 6A and 6B, the respective end portions are arranged at positions close to the end roller 9B and 9Y, and the clearance between the end rollers 9B and 9Y is set. A wound elastic body 14 is continuously provided along the groove 5 portion.

The wound elastic body 14 is a single spring formed in a plate shape along the groove 5 and is fixedly attached to the winch body 2.

In addition, the structure of the wound elastic body 14 is not limited to this, For example, it can also comprise by providing the leaf | plate spring divided | segmented into plurality.

Therefore, the urging force of the springs 12A and 12B connected to the end rollers 9B and 9Y is utilized (selection of elastic force by the springs or adjustment of the mounting position of the springs on the winch main body 2), and the groove 5 side of the rope 20 The rope 20 can be wound and pressed to the groove 5 side by the winding elastic body 14 in conjunction with the pressing of the moving roller body 6A.

For this reason, on the take-in side and the take-out side of the groove 5 which are easily affected by the tension of the tension applied to the rope 20, the groove 5 portion which moves while adjusting the pressure on the rope 20 and is not easily affected by the strength of the tension. Then, since the rope 20 can be pressed and moved, it can be smoothly wound and moved along the groove 5.

In addition, since both ends of the wound elastic body 14 are positioned in the vicinity of the end rollers 9B and 9Y, the length direction of the wound elastic body 14 can be freely adjusted, and the two split The length direction of each of the moving roller bodies 6A and 6B can be adjusted, and the length of the moving roller bodies 6A and 6B on the strong tension side corresponding to the strength of the tension applied to the rope 20 can be adjusted in the length direction. By extending the width, the range of pressure adjustment can be expanded to cope with it, and the length direction of the moving roller bodies 6A and 6B on the weak tension side is shortened to reduce the range of pressure adjustment. Correspond.

Alternatively, the length direction of one moving roller body 6A (connecting a large number of rollers) is formed long, and the length direction of the other moving roller body 6B (connecting one or two rollers or the like) When the tension applied to the rope 20 is weak by forming it short and providing the wound elastic body 14 along the groove 5 according to the distance between the end rollers 9B and 9Y of the moving roller bodies 6A and 6B. It is also possible to press and move the slack or the like generated in the rope 20 along the groove 5 in a long range, and the length direction of each moving roller body 6A, 6B (one or two rollers, etc.) By forming it short and providing the wound elastic body 14 in a wide range along the groove 5, it is possible to cope with a case where there is little change in tension strength.

Further, since the winding elastic body 14 is provided between the end rollers 9B and 9Y of the moving roller bodies 6A and 6B, the end rollers 9B and 9Y of the moving roller bodies 6A and 6B The urging directions of the springs 12A and 12B to be connected can be freely set, and the moving roller bodies 6A and 6B can be easily attached.

Further, by attaching a clearance adjusting mechanism to the wound elastic body 14, the initial incorporation into the groove 5 of the rope 20 can be performed smoothly. That is, by adjusting the amount of the wound elastic body 14 close to the groove 5 side, for example, the distance from the groove 5 is separated and the rope 20 is taken along the groove 5, and then close to the groove 5 side. Thereby, it can adjust so that the rope 20 may be pressed strongly.

The endless winch 1 of the present invention is configured as described above. Next, a case where the endless winch 1 is used to move the rope 20 connected to the net will be described.

First, the drive shaft 3 of the endless winch 1 is rotationally driven using a drive source and the winding drum 4 attached to the drive shaft 3 is rotated, and the rope 20 connected to the net or the seat is connected to the winch body. 2 through one guide roller 7A.

The rope 20 taken in via the guide roller 7A is connected to the connecting plate 10A by the urging force (arrow a) of the elastic body 11A in the connecting plate 10A attached to the support shaft 8A of the guide roller 7A. It is guided and moved to the groove 5 side while being pressed (arrow f) to the groove 5 side by the end roller 9A.

At this time, the rotational movement of the connecting plate 10A is adjusted according to the tension applied to the rope 20.

That is, when the tension applied to the rope 20 is strong, the rope 20 is strongly pulled linearly, and the end roller 9A is strongly moved outward (in a direction away from the groove 5 (arrow e) against the bias of the spring 11A. )), The rotational movement of the connecting plate 10A toward the groove 5 is small, and the rope 20 is guided toward the groove 5 at the position away from the guide roller 7A (arrow f). The interlocking moving roller body 6A is pressed toward the groove 5 side by the moving roller body 6A while being pulled strongly (against the biasing force of the spring 12A (arrow m)) toward the guide roller 7A.

When the tension applied to the rope 20 is weak, the pulling force of the rope 20 is weak, the biasing force (arrow a) by the spring 11A is strong, and the rotation of the connecting plate 10A toward the groove 5 is large. The rope 20 is guided and moved toward the groove 5 near the position (arrow f), and the moving moving roller body 6A is weakened toward the guide roller 7A (to the bias of the spring 12A (arrow m)). And moving while being pulled and wound around the groove 5 by the moving roller body 6A.

Next, the rope 20 guided and moved to the groove 5 of the winding drum 4 has the strength of the urging (arrow a) of the connecting plate 10A by the spring 11A corresponding to the strength of the tension applied to the rope 20, and the winding. The moving roller body 6A is moved along the groove 5 by a desired amount by a combination of the rotation direction (arrow d) of the rotating drum 4 and the biasing force (arrow m) by the spring 12A.

That is, the rotating direction of the winding drum 4 (arrow d) and the biasing direction by the spring 12A (arrow m) have a synergistic effect in the same direction, and the biasing direction of the spring 11A (arrow a) is reversed. The amount of movement of the moving roller body 6A synchronized with the rotation direction of the winding drum 4 of the moving roller body 6A is finely adjusted by the combination of the magnitudes of the action of each force. The Rukoto.

For this reason, the pressing position and the pressing force to the groove 5 side by the moving roller body 6A are adjusted corresponding to the strength of the tension applied to the rope 20, and the end roller 9B portion on the rear end side along the groove 5 is adjusted. It winds around the winding drum 4.

Thereafter, the wound elastic body attached along the groove 5 with one end side close to the end roller 9B of the moving roller body 6A and the other end side close to the end roller 9Y of the moving roller body 6B. 14, the rope 20 is moved to the end roller 9Y portion of the other moving roller body 6B while being wound and pressed to the groove 5 side continuously to the end roller 9B.

At this time, the moving roller body 6B is attached by the rotation direction (arrow d) of the winding drum 4 and the urging (arrow z) of the winding drum 4 by the spring 11B in the rotation direction, and the spring 12B. The amount of movement of the moving roller body 6B synchronized with the rotation direction of the winding drum 4 is finely adjusted by the combination with the force (arrow n).

For this reason, the rope 20 pressed to the groove 5 side by the wound elastic body 14 is adjusted along the groove 5 side while adjusting the pressing force from the end roller 9Y side of the moving roller body 6B to the groove 5 side. It winds around the moving roller body 6B.

The rope 20 wound and moved along the groove 5 is separated from the groove 5 in a state where the end roller 9Z portion is pressed toward the groove 5 side (arrow v) by the urging force of the moving roller body 6B. Then, it is taken out from the winch body 2 through the guide roller 7B.

In this way, since each of the moving roller bodies 6A and 6B and the wound elastic body 14 are connected in series and press the rope 20 along the groove 5, it is possible to reliably cope with the strength of the tension applied to the rope 20. The rope 20 can be smoothly moved while being pressed.

In addition, since each of the moving roller bodies 6A and 6B and the wound elastic body 14 are arranged in series, the length along the respective grooves 5 can be freely adjusted, and the tension applied to the rope 20 can be adjusted. It can respond to strength (when the tension is strong, it is provided in a long range along the groove 5; when the tension is weak, it can be handled with a short length only on the guide rollers 7A and 7B side), and a smooth rope 20 movements are possible.

In addition, since the one moving roller body 6A and the other moving roller body 6B are attached to the winch body 2 in an independent state, the tension applied to the rope 20 on the intake side, The rope 20 is configured so as to individually respond to the strength of the tension applied to the rope 20 to enable the rope 20 to move smoothly.

Further, the end roller 9B, 9Y opposite to the guide roller 7A, 7B of each moving roller body 6A, 6B is connected to the spring 12A, 12B and is biased toward the spring 12A, 12B. Even on the end rollers 9B and 9Y side, the rope 20 can be wound around the groove 5 while reliably pressing the springs 12A and 12B against the groove 5 side, and the rope 20 can be smoothly moved.

In the first embodiment, the connecting plates 10A and 10B biased by the springs 11A and 11B rotate about the support shafts 8A and 8B. In the present invention, the connecting plates 10A and 10B have the same structure. For example, the coupling plates 10A and 10B can be freely inserted into the support shafts 10A and 10B through the long holes so that the tension of the rope 20 applied to the coupling plates 10A and 10B is increased or decreased. Is moved further to finely adjust the positions of the end rollers 9A and 9Z toward the groove 4, and further fine adjustment of the moving amount of the moving roller bodies 6A and 6B linked to the connecting plates 10A and 10B is performed. Can also be performed.

Further, in the first embodiment, the two divided moving roller bodies 6A and 6B are formed to have an equal length. However, in the endless winch 1 of the present invention, each moving roller body 6A and 6B. This length is not limited to this, and by adjusting the length direction of the wound elastic body 14, for example, one moving roller body 6A is formed longer and the other moving roller body 6B is By forming it short, it is possible to appropriately press and move the incorporated rope 20 to cope with the strength of the tension.

Further, in the first embodiment, the end rollers 9A and 9Z of the moving roller bodies 6A and 6B are coupled (supported) to the coupling plates 10A and 10B. However, in the endless winch of the present invention, the coupling plates 10A and 10B 10B and the moving roller bodies 6A and 6B are not limited to this. For example, a separate roller (not shown) is rotatably supported on the connecting plates 10A and 10B. It is also possible to connect the end rollers 9A and 9Z of the moving roller bodies 6A and 6B.

In the first embodiment, the two moving roller bodies 6A and 6B are used. However, in the endless winch 1 of the present invention, the shape of the moving roller bodies 6A and 6B is limited to this. Instead, for example, the moving roller body 6A is provided only on one side of the guide roller 7A, and the wound elastic body 14 is provided along the other guide roller 7B from the vicinity of the end roller 9B of the moving roller body 6A. Thus, the rope 20 can be pressed and moved to the groove 5 side.

In the first embodiment, the end rollers 9A and 9Z of the moving roller bodies 6A and 6B are connected via the connecting plates 10A and 10B. However, in the endless winch 1 of the present invention, the moving roller body 6A is connected. , 6B to move to one end side is not an essential condition, and the end rollers 9A, 9Z can be directly supported on the winch body 2 respectively.

Furthermore, in the first embodiment, the pair of guide rollers 7A and 7B are rotatably attached to the support shafts 8A and 8B attached to the winch body 2, respectively.
