Field of the Invention The present invention relates to a conveyor belt mechanism and a seamless belt for an operation test apparatus such as a wind tunnel test apparatus. [Prior Art] In order to evaluate the operational performance or aerodynamic performance of a test body such as an automobile, an operation test apparatus having a conveyor belt mechanism is used as described in JP2007-101410A (Japanese Laid-Open Patent Publication). This operation test apparatus is provided with a conveyor belt mechanism in which a seamless belt made of steel is wound around a pair of rollers composed of a drive roller and a driven roller. The test body wheel is carried on the conveyor belt mechanism, and by rotating the seamless belt, the seamless belt is used as a simulated road surface operation, and a test environment equivalent to the operation test for running the test body on the actual road surface is realized on the operation test equipment. In such a conveying belt mechanism, the bending deformation of the center portion on the outer peripheral side of the belt occurs in a relatively short time at both end portions in the width direction of the seamless belt, and the life of the seamless belt becomes short. SUMMARY OF THE INVENTION In view of the above circumstances, the present invention provides a conveyor belt mechanism and a seamless belt for operating a test device, which are less susceptible to deformation such as bending in a seamless belt, and to achieve a longer life of the seamless belt. The conveyor belt 201131155 for operating test equipment according to the embodiment of the present invention has a serpentine correction roller that winds a seamless belt and corrects the meandering of the seamless belt by tilting around the vertical axis of the rotary shaft, wherein none The inner peripheral surface of the slit belt is provided with an inner peripheral side protective thin layer, and the inner peripheral side thin layer is used to protect the inner peripheral surface over about the entire circumference, and the seamless belt has a degree of substantial deformation without being applied by the applied stress. The flexural rigidity causes the seamless belt to bend due to the distortion of the circumferential side protective layer. The inventor of the present invention, through a lot of experimental and technical results, found that the damage of the inner peripheral surface of the seamless belt caused by the contact of the roller or the snake correction roller and the seamless belt was expanded by the meandering correction roller to cause the helmet seam ^ Belt deformation] According to the configuration of the embodiment of the present invention described above, since the inner circumference of the seamless belt is protected by the inner peripheral side protective sheet, the inner peripheral surface of the seamless belt is not damaged. Further, since the seamless belt has a bending rigidity which does not cause the stress of the protective film to substantially deform the seamless belt on the circumference 4, even if the inner peripheral side protective sheet is deformed, the seamless belt does not bend or the like. Deformation. Further, the bending rigidity of the seamless belt is 10 times or more of the = bending rigidity of the inner peripheral side protective sheet. More preferably, the bending rigidity of the seamless belt is 1 time or more of the bending rigidity of the inner peripheral side protective sheet. Further, the longitudinal elastic modulus of the inner peripheral side protective sheet is 〇〇2 (GPa) or more. More preferably, the longitudinal elastic modulus of the inner peripheral side protective layer is 〇 1 (Gpa ) or more. Further, the transverse elastic modulus of the inner peripheral side protective layer is 〇 〇 1 (GPa) or more. More preferably, the transverse elastic modulus of the inner peripheral side protective layer is 〇 〇 2 (GPa) or more. 4 201131155 μ Protection with the longitudinal elastic modulus and the transverse elastic modulus of the above-mentioned size. Negatively, it has a sufficiently high rigidity for the compression load in the thickness direction and the cutting along the plane direction. The inner peripheral side protects the thin layer and is smashed by the rolling [and the seamless belt is subjected to the compression load in the above direction and the cut-off negative] but because the inner peripheral side protective thin layer is loaded with these compressions and cut-offs, ^ Rigid body, so the vibration caused by the test performance of the bomb-running test equipment based on the inner peripheral side protective layer will not be produced on the seamless belt. The crucible may be individually provided for the meandering correction roller and the pair of rollers to abut against the edge roller of the seamless belt. For example, one end of the edge roller is driven to move downward, so that the edge is turned toward the edge, and one end of the edge roller is moved toward the side of the test body in the backward direction of the test body: The drive is such that M a is abutted against the outer peripheral surface of the seam belt by a thin layer of the (four) side (four). The outer circumference can be formed on the outer peripheral surface of the seamless belt, and the λ = circumferential side protective thin layer is used to cover the outer peripheral side protective layer over the entire circumference of the ==== abutting the seamless belt. The applied seam will be bent due to the bending of the non-layer due to the bending rigidity. In this case, the outer peripheral structure of the factory is glued and attached to the seamless belt or the 疋 '... 修修' is the aforementioned - for any of the rollers, 201131155 one end of the snake correction roller for testing In the direction of travel of the body, the other end is driven to move in the backward direction of the test body to tilt the meandering correction roller. Further, the inner peripheral side protective sheet may be attached to the inner peripheral surface of the seamless belt by, for example, gluing. Further, the steel seamless belt according to the embodiment of the present invention is provided with an inner peripheral side protective sheet on the inner peripheral surface thereof, and the inner peripheral side protective sheet is used to protect the inner peripheral surface over approximately the entire circumference, and further The seamless belt is not bent to be substantially deformed by the applied stress, and the applied stress causes the seamless belt to bend due to the distortion of the inner peripheral side protective sheet. [Embodiment] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

That is, the left side in the first figure is defined as the front side in the front-rear direction, the right side in the first figure is defined as the rear side in the front-rear direction, the back side of the paper is defined as the right side in the width direction, and the side of the paper sheet is defined as the left side in the width direction. The conveyance belt mechanism 10 includes a follower 6 201131155, a double cylinder li and a drive roller 12', and a driven roller η and a driven edge roller. Further, the seamless belt 14 is wound around the driven roller u, the drive 5 " and the edge roller 13. The swaying rf cylinder 11 and the driving drum 12' are respectively widened in the axial direction of the rotation, and the driving drum 12 is rotated clockwise in the figure, and the upper dam portion A is lightly moved from the front side to the rear side in the front-rear direction. On the driven roller u, the drive roller 12 and the edge and side button °11. Then, with the frictional force between the seamless belt 14 and the driven roller 11 ϊίί, the driven roller 11 and the side _13 are fed clockwise in the figure with the upper movement of the seamless leather ^4 == =, the door motor 16疋 driven by the drum 12 can precisely control the speed j, and can drive the drive roller 12 back at the desired speed of rotation = that is, in Benni County, in the desired week Speed down ^: move. Further, the rotation and stop of the servo motor 16 are controlled by the controller 30. It is stated that the wind supply unit 20 is described. The wind supply unit 20 is provided with a second guide S 21 and a blower fan 22. The air gap of the air duct 21 is disposed on the rear side in the front-rear direction of the vehicle C (the right side in the drawing), and the outlet 2lb is disposed on the front side in the front-rear direction of the vehicle sill (on the left side in the drawing). The air-through fan 22 is disposed inside the air duct 21, and the air blower fan 22 is driven to carry in air from the air duct 21 to supply air to the vehicle c from the air outlet 21b. 3, the blower fan 22 is driven by the inverter motor 23. The inverter motor 23 is a motor that can precisely control the rotation speed of 201131155, and can precisely control the wind speed of the wind sent to the car C. Further, the rotation and stop of the inverter motor 23 and the number of revolutions are controlled by the controller 30. As described above, in the present embodiment, the seamless belt 14 that simulates the road surface is rotated at a desired peripheral speed and the wind of the desired wind speed is sent from the front of the automobile C, thereby the same environment as when the automobile c is operated outside the house. Reproduce in the state where the car c is stationary. The edge roller 13 is disposed in the width direction of the rotation axis. Further, the edge light 13' abuts against the inner peripheral surface 14i in the lower portion 14b of the seamless belt 14, and a uniform tension is applied to the seamless belt 14. Further, the pair of bearings 15a' supporting the edge roller 13 at both ends in the width direction are connected to the actuator i5b, and the actuator 15b is for moving at least one of the bearings 15a in the vertical direction.

=態的結構是共通的，所以以相異於第一實施形態處為 —心來說明。又，相同或對應於第一實施形態的元件， 賦予相同或類似的符號，而省略詳細說明。 本實施形態中，修正無縫皮帶14的蛇行的邊緣輥 ，於無縫皮帶14的下部14b，是抵接於外周面14〇， 方加均勻張力於無縫皮帶14。又，邊緣輥13,，其軸方 201131155 向向者寬方向而被配置。又’在寬方向兩端支持邊緣幸昆 13’的一對軸承15a’，促動器15b’被連接，促動器15b' 用來將軸承15a'的至少一者往上下方向移動。以驅動促 動器15b'，使軸承15a'的一者往上，及/或他者往下移 動，可以在垂直於前後方向的面内將邊緣輥13'傾斜。 又，促動器15b’被控制器30控制。 本實施形態中，當邊緣輥13’被傾斜成邊緣輥13’ 的寬方向左端是相對於寬方向右端位於上方，則施加於 無縫皮帶14的張力，在寬方向左側的張力是大於寬方 向右側的張力。結果，在無縫皮帶14，施加向寬方向 右側的力而往寬方向右側移動。另一方面，當邊緣幸昆 13’被傾斜成邊緣輥13’的寬方向左端是相對於寬方向右 端位於下方，則施加於無縫皮帶14的張力，在寬方向 左側的張力是小於寬方向右側的張力。如此，以傾斜邊 緣輥13’，可以使無縫皮帶14往寬方向移動。本實施形 態的傳送皮帶機構10，具有用來檢測無縫皮帶14的蛇 行（即無縫皮帶14的寬方向的位置偏離）的圖未顯示 的蛇行檢測感應器，控制器30根據蛇行檢測感應器的 檢測結果，控制促動器15b’，使得邊緣輥13'朝修正蛇 行方向傾斜。 又，上述結構中，邊緣輥13’控制成被傾斜於前後 方向的軸周圍，但本發明並不限定於上述結構。也就是 說，邊緣輥13'也可以是被傾斜於上下方向的軸周圍 (即，促動器15b’將軸承15a'的至少一者往前後方向移 動）的結構。這種狀況，因為在傾斜的邊緣輥13'的軸 201131155 方向會產生大摩擦力，所以以該摩擦力無縫皮帶14會 往寬方向移動。 邊緣輥13'未被傾斜（即邊緣輥13'的回轉軸與寬方 向一致）的狀態下，從邊緣輥13'施加於無縫皮帶14的 摩擦力方向，與前後方向前側一致。在此，當邊緣輥 13 ’被傾斜成邊緣輥13 ’的寬方向左側相對於寬方向右側 是位於前方，則接受在邊緣輥13’的轴方向產生的大摩 擦力，無縫皮帶14往寬方向右側移動。另一方面，當 邊緣輥13’被傾斜成邊緣輥13’的寬方向左側相對於寬方 向右側是位於前後方向的後側，則上述摩擦力方向向寬 方向左側被傾斜，無縫皮帶14往寬方向左側移動。 本實施形態中，為了防止發生於無縫皮帶14的彎 曲等變形，分別以膠接劑貼附保護薄層17於無縫皮帶 14的内周面14i，貼附保護薄層19於外周面14〇。本實 施形態中，保護薄層17、保護薄層19為相同材料，厚 度也相等。又，保護薄層19的寬方向尺寸等於無縫皮 帶14的寬方向尺寸W，且無縫皮帶14的外周面14〇 被保護薄層19被覆約全部周面。 如上所述，本實施形態中，與第一及第二實施形態 不同，於無縫皮帶14的外周面14〇，為了由邊緣輥13' 的接觸所產生的傷害不被形成，而以保護薄層19保護 外周面14〇。因此，防止在無縫皮帶14的外周面14〇 產生的傷害導致無縫皮帶14之彎曲等變形發生。 又，於保護薄層19要求的彎曲剛性，與設於無縫 皮帶14的内周面14i的保護薄層Π所要的是相同的。 201131155 也就是說，無縫皮帶14的彎曲剛性，足夠比保護薄層 19大即可。具體來說，無縫皮帶14對於保護薄層19 的彎曲剛性的比，較佳為10以上，更佳為100以上。

The seamless elastic belt 14 has a longitudinal elastic modulus ratio (£8疋5) of about 115 〇 2 to 2300 for the protective thin layer 17, and a thickness ratio (64) of about 5.5 to 0.75 ' The bending rigidity ratio (Bb/Bs) for the protective thin layer I is about 143 to 971. In the present embodiment, 'the inner circumferential surface 14i of the seamless belt 14 as described above, 201131155 = protection, the driven roller U, the driving roller 12 or the side: the roller 3 seamless belt 14 is not in direct contact, and does not exist on the inner circumferential surface ^ 14^^ harm. Therefore, in the configuration of the present embodiment, the damage of the seamless skin surface is expanded, and the occurrence of the seamless belt 14 is less likely to occur. As a result, in the present embodiment, the edge of the seamless belt 14 is in contact with the protective thin layer (10), and the inner peripheral surface 17e of the protective thin layer 17 is damaged along the ^= direction, so 13 tilting axis ^ * Protecting the damage of 4 layers of 17 layers, it is possible to bend in the protective thin layer 17 single. However, as described above, since the bending rigidity B b of the seamless belt 14 is sufficiently larger than the bending rigidity B s of the protective sheet layer 7 , even if the damage of the protective sheet layer 17 is enlarged, the seamless belt 14 does not bend. . The compression load in the thickness direction of the protective sheet 17 is applied to the portion of the driven roller 11 and the driving roller 12 that protect the layer. Further, with the frictional force acting between the rotating drive roller/two π Η and the + protective thin layer 17, the protective thin layer 17 is applied with a cut-off load along the surface direction thereof. Since the protective layer Η is an elastic body, the portion of the roller that protects the thin layer 17 and the seamless belt 14 ’ operates as a spring. When the = coefficient of the protective thin layer 17 becomes small, the amount of deformation of the protective thin layer 17 that is held between the drum and the seamless belt 14 becomes large, and there is a possibility of occurrence of large vibration in the rotating seamless belt 14. . That is, the protective thin layer 17 preferably has a longitudinal elastic modulus and a transverse elastic modulus 'for a compressive load or a cut-off load applied to the protective thin layer 17, and the protective thin layer 17 can be sufficiently ^201131155 as a rigid body (ie, The vibration of the seamless belt 14 caused by the deformation of the protective sheet 17 or the seamless belt 14 following the action of the driving drum 12 is ignored. In the present embodiment, the longitudinal elastic modulus Es of the protective thin layer 17 is 0.1 to 0.2 GPa, and the transverse elastic modulus Gs of the protective thin layer 17 is 0.035 to 0.07 GPa. The size of Es and Gs is the compression load or the cut-off load applied to the protective sheet 17, and the protective sheet 17 can be sufficiently regarded as the size of the rigid body. Further, in the present embodiment, the ratio (Bb/Bs) of the bending rigidity of the seamless belt loop 4 to the protective sheet layer 17 is 143 to 971, but the present invention is not limited to the above configuration. That is to say, the bending rigidity of the seamless belt 14 can also be sufficiently larger than the protective thin layer 17. Specifically, the bending rigidity ratio of the seamless belt 14 to the protective thin layer 17 may be 10 or more, more preferably 100 or more. Further, in the present embodiment, the protective thin layer 17 has a longitudinal elastic modulus Es of 0.1 to 0.2 GPa and a transverse elastic modulus Gs of 0.035 to 0.07 GPa. However, the present invention is not limited to the above configuration. That is, the longitudinal elastic modulus and the transverse elastic modulus of the protective thin layer 17 may be such that the protective thin layer 17 is sufficiently regarded as the rigid body for the compression load or the cut-off load applied to the protective thin layer 17. Specifically, the longitudinal elastic modulus of the protective thin layer 17 may be 〇. 2 GPa or more, more preferably O. IGPa or more. Further, the transverse elastic modulus of the protective thin layer 17 may be O.OIGPa or more, more preferably 0.02 GPa or more. Next, the mounting steps regarding the protective thin layer 17 to the seamless belt 14 will be explained. The third figure shows a protective thin film 12 201131155 layer π installed in front of the seamless belt 14, and the fourth figure is a part of the developed image to which the protective thin layer == is attached. As shown in the third picture: = 2 attached to the front of the seamless belt 14, protection thin layer I?, long side w, " / « / for coffee ~ employment surface, width (interval between long sides) s: leather knife is slightly larger than The width dimension w of the seamless belt 14 is flat = SI: A, the angle between the long side 17L of the protective sheet 17 and the short side 17S (9 is about 45. Next, a plurality of protective thin layers are used 17, with its longevity f::彖4:f:14e parallel, and the protective thin layer 17 beyond the seamless enamel layer will protect the surface of the thin layer 17: roll (hand r〇ller) and the like, And avoiding the air in between to attach. In addition, the two adjacent protective thin layers: are subsequently cut off from the part/face (4) of the seamless belt ΐ4 。4 (4) (4). Next, The surface of the protective thin = 7 is so good that it is tapped, and indeed the layer na (second image) is in close contact with the seamless belt 14. The glue of the layer 17 is used to complete the protective layer 17 to the seamless belt. Further, the size of the long side 17L of the protective thin layer 17 or the circumference of the number of sheets 14 of the protective thin layer 17 of the stitching belt 14 is appropriately selected. Implementation form Specific embodiment. 201131155 The seamless belt 14 of the present embodiment is a steel strip of martensitic stainless steel having a width of 500 mm, a circumference of 8500 mm, and a thickness of 0.6 mm. Further, the driven roller 11 and the driving roller 12 have a diameter of 550 mm, and the edge The diameter of the roller 13 is 300 mm. Further, the protective sheet 17 has a thickness of about 1 mm, a longitudinal elastic modulus of 0.18 GPa, and a transverse elastic modulus of 0.06 GPa. The seamless belt 14 is wound around the driven roller with a tension of 200 kN. 11. The driving roller 12 and the edge roller 13. Further, on the inner circumferential surface 14i of the seamless belt 14, five parallel-shaped protective thin layers 17 are attached. The conveying belt mechanism 10 of the above structure is surrounded by the seamless belt 14. The speed is 55 m/s to drive. Further, as a comparative example, the protective thin layer 17 is not attached to the seamless belt 14, and the flat belt wound around the structure of the driven roller 11, the driving roller 12, and the edge roller 13 is In the comparative example, the conveying belt mechanism 10 was continuously driven for ten hours, and bending was observed at both end portions in the width direction of the seamless belt 14. The size of the bending (seamless belt 14 width) Both ends of the direction are in the width direction In the embodiment, even if the conveying belt mechanism 10 is continuously driven for one hundred hours, the bending of the seamless belt 14 is not seen. The wind tunnel testing device 1 according to the embodiment corrects the meandering of the seamless belt 14 by inclining the edge roller 13. However, the present invention is not limited to the above configuration. Next, a second embodiment of the present invention will be described instead. The edge roller 13 is inclined by the driven roller 11, so that the meandering of the seamless belt 14 is alleviated. Fig. 5 is a schematic side view showing a wind tunnel test device 14 201131155 according to a second embodiment of the present invention. Further, the second embodiment is not limited to the structure of the first embodiment described above except for the mechanism for reducing the seam of the seamless belt. Therefore, the second embodiment will be described as being different from the first embodiment. Incidentally, elements that are the same or corresponding to the first embodiment are given the same or similar reference numerals, and the detailed description is omitted. "In the present embodiment, as shown in Fig. 5, 'a pair of bearings 18a supporting the driven roller 11 in the width direction (four), and an actuator 18b for connecting at least the bearing 18a Move in the front and rear direction. The two drive actuators 18b' cause one of the bearings 18a to move forward, and/or the other to move, and the driven roller U can be tilted in the horizontal plane. The actuator 8b is controlled by the controller 30. Ke Tianhui needle 攸 澴 U U, can correct the seamless belt 14 to the width of the technology, the driven roller 11 obliquely into the driven roller. The width direction of the left end relative to the width of the right end is located at the rear, the seam belt The tension of 14 'the tension on the left side of the width direction will be small to the right side of the tension. As a result, in the seamless belt weave, the force to the left side in the width direction is applied, and the force is moved to the left side in the width direction. On the other hand, the 2 ray 11 is inclined so that the left end of the width direction of the (four) roller u is located forward with respect to the width ^ right end, and the tension applied to the seamless belt , is greater than the tension of the right side in the width direction. As a result, at ii, the force to the right side in the width direction is applied, and the movement to the width is inclined by the slave material 11, so that the seamless belt is 1 〇 and the right side is moved. The conveyance belt mechanism of the present embodiment detects a meandering detection sensor not shown in the figure of the meandering of the seamless belt 14 (i.e., the positional deviation of the seamless belt 14, ..., 201131155) The controller 30 controls based on the detection result of the meandering detection sensor. The actuator 18b causes the driven roller 11 to incline toward the correction meandering direction. Further, in the present embodiment, the driven roller 11 is inclined to correct the meandering of the seamless belt 14, but the drive roller 12 may be inclined to correct the seamless belt 14 to be meandered. In the present embodiment, as in the first embodiment, there is a mechanism for correcting the meandering of the seamless belt 14, so that the seamless belt 14 may be bent or broken. Thus, in the present embodiment, the protective thin layer 17 is attached to the inner peripheral surface 14i of the seamless belt 14, as in the first embodiment. In the first and second embodiments of the present invention described above, the edge roller 13 (first embodiment) or the driven roller 11 (second embodiment) for preventing the meandering of the seamless belt 14 is separated by a protective film. The layer 17 abuts against the inner peripheral surface i4i of the seamless belt 14. However, the present invention is not limited to the above configuration. Next, a third embodiment of the present invention will be described in which the edge roller abuts against the outer circumferential surface of the seamless belt 14. Figure 6 is a schematic side view of a wind tunnel test apparatus 第三 according to a third embodiment of the present invention. Moreover, the wind tunnel test device quot" is not the same as the first embodiment of the above-described embodiment except for the mechanism for reducing the seamless skin and the meandering, so it is different from the first embodiment. - Heart to explain. It is to be noted that the same or similar reference numerals are given to the elements that are the same or corresponding to the first embodiment, and the detailed description is omitted. In the present embodiment, the meandering edge roller of the seamless belt 14 is corrected, and the lower portion 14b of the seamless belt 14 abuts against the outer peripheral surface 14A, and the uniform tension is applied to the seamless belt 14. Further, the edge roller 13 is disposed such that its axial direction 201131155 is oriented in the width direction. Further, the pair of bearings 15a' supporting the edge of the edge of the fortune 13' are supported at both ends in the width direction, and the actuator 15b' is used to move at least one of the bearings 15a' in the up and down direction. By driving the actuator 15b' to move one of the bearings 15a' up, and/or the other to move downward, the edge roller 13' can be tilted in a plane perpendicular to the front-rear direction. Further, the actuator 15b' is controlled by the controller 30. In the present embodiment, when the edge roller 13' is inclined such that the left end of the edge roller 13' in the width direction is positioned above the right end in the width direction, the tension applied to the seamless belt 14 is greater in the width direction on the left side in the width direction than in the width direction. The tension on the right side. As a result, the seamless belt 14 is applied to the right side in the width direction and moved to the right side in the width direction. On the other hand, when the edge Xingkun 13' is inclined such that the left end of the edge roller 13' in the width direction is located below the right end with respect to the width direction, the tension applied to the seamless belt 14, the tension on the left side in the width direction is smaller than the width direction The tension on the right side. Thus, the seamless belt 14 can be moved in the width direction by the inclined edge roller 13'. The conveying belt mechanism 10 of the present embodiment has a meandering detecting sensor for detecting the meandering of the seamless belt 14 (i.e., the positional deviation of the seamless belt 14 in the width direction), and the controller 30 is based on the meandering detecting sensor. As a result of the detection, the actuator 15b' is controlled such that the edge roller 13' is inclined toward the correction meandering direction. Further, in the above configuration, the edge roller 13' is controlled to be inclined around the axis in the front-rear direction, but the present invention is not limited to the above configuration. That is, the edge roller 13' may be configured to be inclined around the axis in the vertical direction (i.e., the actuator 15b' moves at least one of the bearings 15a' in the front-rear direction). In this case, since a large frictional force is generated in the direction of the axis 201131155 of the inclined edge roller 13', the seamless belt 14 is moved in the width direction by the frictional force. In a state where the edge roller 13' is not inclined (i.e., the rotation axis of the edge roller 13' coincides with the width direction), the frictional force applied from the edge roller 13' to the seamless belt 14 coincides with the front side in the front-rear direction. Here, when the edge roller 13' is inclined such that the left side in the width direction of the edge roller 13' is located forward with respect to the right side in the width direction, the large friction force generated in the axial direction of the edge roller 13' is received, and the seamless belt 14 is widened. Move to the right of the direction. On the other hand, when the edge roller 13' is inclined such that the left side in the width direction of the edge roller 13' is the rear side in the front-rear direction with respect to the right side in the width direction, the above-mentioned frictional force direction is inclined to the left side in the width direction, and the seamless belt 14 is turned toward Move to the left in the width direction. In the present embodiment, in order to prevent deformation such as bending of the seamless belt 14, the protective thin layer 17 is attached to the inner peripheral surface 14i of the seamless belt 14 with a bonding agent, and the protective thin layer 19 is attached to the outer peripheral surface 14 Hey. In the present embodiment, the protective thin layer 17 and the protective thin layer 19 are made of the same material and have the same thickness. Further, the width dimension of the protective sheet 19 is equal to the width dimension W of the seamless belt 14, and the outer peripheral surface 14 of the seamless belt 14 is covered by the protective sheet 19 to the entire circumference. As described above, in the present embodiment, unlike the first and second embodiments, the outer peripheral surface 14 of the seamless belt 14 is not formed to be damaged by the contact of the edge roller 13'. The layer 19 protects the outer peripheral surface 14A. Therefore, the damage generated on the outer peripheral surface 14 of the seamless belt 14 is prevented from causing deformation such as bending of the seamless belt 14 to occur. Further, the bending rigidity required for the protective sheet 19 is the same as that of the protective sheet provided on the inner peripheral surface 14i of the seamless belt 14. 201131155 That is to say, the bending rigidity of the seamless belt 14 is sufficiently larger than the protective thin layer 19. Specifically, the ratio of the bending rigidity of the seamless belt 14 to the protective thin layer 19 is preferably 10 or more, and more preferably 100 or more. The above is illustrative of the embodiments of the invention. The configuration of the embodiment of the present invention is not limited to the above description, and can be arbitrarily changed within the scope of the technical idea expressed by the description of the patent application. For example, in the first and second embodiments of the present invention described above, the automobile C is used as the test body, but the present invention is not limited to the above configuration. That is, a vehicle other than a car (for example, a vehicle that does not use a prime mover or a mock-up model that evaluates the aerodynamic characteristics of the car), an airplane, or a wheel or a suspension unit of the vehicle is used as The conveyor belt mechanism used in the test apparatus of the test body is also included in the conveyor belt mechanism for operating the test equipment according to the embodiment of the present invention.
