As shown in FIG. 2, a longitudinal groove 252 is also present between a left guide protrusion 261 and a right guide protrusion 262 described later.

  Although not necessarily limited to this, in this example, the longitudinal groove portion 252 of the groove 250 is provided as a positioning structure of the second flat plate portion 320 of the leaf spring 300. Positioning protrusions separated from each other on the left and right sides may be provided on the first bottom surface 27 without providing the second bottom surface 28. However, this example is more advantageous in reducing the thickness of the male member 500.

  As briefly illustrated in FIG. 1, the operating body arrangement recess 20 is provided with a guide protrusion 260 that guides introduction of the second flat plate portion 320 of the leaf spring 300 into the longitudinal groove portion 252 which is an example of a positioning structure. . In this example, the guide protrusion 260 is provided separately in the left-right direction, and the guide protrusion 260 includes a left guide protrusion 261 and a right guide protrusion 262. As illustrated in FIG. 2, the guide protrusion 260 is a plate in the process of being guided by the guide surface 2601 that is close to the second bottom surface 28 and being guided by the guide surface 2601 as it approaches the distal end side of the operation body 400. A position restricting wall 2605 that restricts displacement of the second flat plate portion 320 of the spring 300 in the left-right direction is provided. The left guide protrusion 261 has a guide surface 2611 and a position restriction wall 2615. The right guide protrusion 262 includes a guide surface 2621 and a position restriction wall 2625.

  When the operating body 400 is placed in the operating body placement recess 20 of the insertion portion 210 in a state where the leaf spring 300 is housed in the leaf spring housing portion 411 of the operating body 400, the leaf spring 300 is externally provided by the opaque metallic operating body 400. May not be visible. By providing the guide protrusion 260 as in the present example, the leaf spring 300 can be appropriately disposed in the operating body disposition recess 20 even in such a case, and the intended operation of the leaf spring 300 can be ensured more accurately. can do.

  When the guide protrusion 260 that protrudes upward from the bottom surface of the operation body disposition recess 20 is provided, the guide protrusion 260 may interfere with the operation body 400, and the operation body 400 is formed on the bottom surface of the operation body disposition recess 20. Lodging can be inhibited. In this example, as shown in FIG. 5, a guide protrusion accommodating portion 460 that accommodates the guide protrusion 260 is provided on the lower surface of the operation body 400, thereby favorably overturning the operation body 400 on the bottom surface of the operation body disposition recess 20. Can be secured.

  The guide protrusion accommodating portion 460 includes a left guide protrusion accommodating portion 461 that accommodates the left guide protrusion 261 and a right guide protrusion accommodating portion 462 that accommodates the right guide protrusion 262. The left guide protrusion accommodating portion 461 and the right guide protrusion accommodating portion 462 communicate spatially, and further, these communicate spatially with the leaf spring accommodating portion 411. According to this aspect, a T-shaped recess is provided on the lower side of the operation body 400. When the operating body 400 is pushed downward, the left guide protrusion 261 is accommodated by the left guide protrusion accommodating portion 461, and the right guide protrusion 262 is accommodated by the right guide protrusion accommodating portion 462. When the operating body 400 is not pushed downward, the left guide protrusion 261 is not accommodated by the left guide protrusion accommodating portion 461 and the right guide protrusion 262 is not located on the right side from the viewpoint of securing the assembly described with reference to FIG. It is not accommodated by the guide protrusion accommodating portion 462.

  A claw 450 is provided in the middle of the left and right guide protrusion accommodating portions 461 and the right guide protrusion accommodating portion 462. When the operation body 400 is pushed down, the claw 450 can be engaged with the rearmost side surface 25 of the rearmost side of the vertical groove portion 252 of the groove 250 of the operation body disposition recess 20. 3A, the claw 450 has a rear surface 4501 that is substantially perpendicular to the insertion direction, and an inclined surface 4502 that is inclined from the lower end of the claw 450 toward the front end protrusion 430 from the rear fin portion 440. .

  The assembly of the male member 500 will be described with reference to FIG. First, the leaf spring 300 is accommodated in the leaf spring accommodating portion 411 of the operating body 400 in advance, whereby the first flat plate portion 310 of the leaf spring 300 is located between the left inner surface 4115 and the right inner surface 4116 of the leaf spring accommodating portion 411. It will be in the state where it was restricted or pinched by. In some cases, the front end portion of the first flat plate portion 310 of the leaf spring 300 is in contact with the rear inner surface 4112 of the rear wall portion 417 and is regulated in position. Next, as shown in FIG. 6A, the rear fin portion 440 of the operating body 400 is inserted into the rear slot 240. At this time, the tip of the second flat plate portion 320 of the leaf spring 300 contacts the guide surface 2621 of the guide protrusion 260.

  Next, as shown in FIG. 6B, the tip protrusion 430 of the operating body 400 is inserted into the protrusion holding slot 230. In this state, the second flat plate portion 320 of the leaf spring 300 may not be accommodated in the vertical groove portion 252. By pushing down the operating body 400 to the bottom surface side of the operating body disposing recess 20, the second flat plate portion 320 of the leaf spring 300 is guided by the inclined surface 4502 of the claw 450 and the guide surface 2601 of the guide protrusion 260, and It is guided to the second bottom surface 28 of the bottom surface and is received in the longitudinal groove portion 252. As shown in FIG. 6C, the distal end portion of the second flat plate portion 320 of the leaf spring 300 abuts on the guide surface 2601 of the guide projection 260, thereby restricting the rearward displacement of the leaf spring 300. If the guide surface 2601 is not provided, the rearward displacement of the leaf spring 300 is restricted by an arbitrary side surface of the vertical groove portion 252.

  After the male member 500 is assembled, the male member 500 is difficult to disassemble. For example, it is difficult to remove the operation body 400 from the male member main body 200. When the operating body 400 is not pushed down, for example, as shown in FIG. 6C, the end surface of the tip of the second flat plate portion 320 of the leaf spring 300 abuts on the guide surfaces 2601 of the left and right guide protrusions 260, Displacement of the operation body 400 rearward in the insertion direction becomes difficult. At this time, since the rear fin portion 440 is restricted from being displaced upward by the flange portion 220, it is difficult for the distal end portion of the second flat plate portion 320 of the leaf spring 300 to be displaced upward along the guide surface 2601. It is.

  It is difficult to disassemble the male member 500 even when the operating body 400 is pushed down. For example, it is difficult to remove the operation body 400 from the male member main body 200. When the operating body 400 is pushed downward, the claw 450 engages with the rear side surface 25 of the longitudinal groove portion 252 as shown in FIG. At this time, as shown in FIG. 7B, the left guide protrusion 261 is accommodated in the left guide protrusion accommodating portion 461, and similarly, the right guide protrusion 262 is accommodated in the right guide protrusion accommodating portion 462. Even if the body 400 is to be displaced backward, the displacement of the operating body 400 is prevented by contact between the left guide protrusion 261 and the left guide protrusion accommodating portion 461 or contact between the right guide protrusion 262 and the right guide protrusion accommodating portion 462. Thus, once the male member 500 is assembled, it is difficult to return it to the original separated state.

  When the claw 450 and the rear side surface 25 of the vertical groove portion 252 are engaged as shown in FIG. 7A, the guide projection 260 at the rear end portion of the vertical groove portion 252 is shown in FIG. The guide projection accommodating portions 460 on the left and right sides of 450 are accommodated, and interference between the guide projection 260 and the operation body 400 is avoided.

  A connection process between the male member 500 and the female member 600 will be described with reference to FIGS. As shown in FIG. 8, a cutout 630 is provided in the peripheral wall 640 of the female member 600. When the operating body 400 is inserted into the peripheral wall portion 640 of the female member 600, the operating convex portion 410 is received by the notch 630, so the operating convex portion 410 is inserted between the upper wall portion 641 and the lower wall portion 642. Thus, it is not necessary to push down the entire device, and the buckle 100 can be suitably reduced in thickness.

  As shown in FIG. 9, the engaging convex portion 420 is pushed down to the lower wall portion 642 side of the peripheral wall portion 640 by the stop wall 655 of the upper wall portion 641 of the peripheral wall portion 640 of the female member 600. Since the stop wall 655 is provided with the inclined surface 6502, the engaging convex portion 420 is gradually pushed down by the inclined surface 6502 after the engaging convex portion 420 collides with the stop wall 655, that is, smooth insertion is performed. Secured. At this time, the operating body 400 is displaced from the second position as the initial position to the first position as the displacement position.

  When the male member 500 is further advanced from the state shown in FIG. 9 to the back side of the peripheral wall portion 640 of the female member 600, the male member 500 and the female member 600 are locked as shown in FIG. The engaging convex portion 420 is pushed down in the direction of approaching the bottom surface of the operating body arranging concave portion 20 against the elasticity of the leaf spring 300 by the stop wall 655 during the insertion process, but after passing below the stop wall 655. The elastic force of the leaf spring 300 urges the upper side away from the bottom surface of the operating body disposing recess 20 to come into contact with the upper wall 641 of the peripheral wall 640. As a result, the stop wall 655 and the engagement convex portion 420 can be engaged with each other, the stop surface 6501 of the stop wall 655 and the rear surface 4212 of the engagement convex portion 420 are arranged to face each other, and the stop surface 6501 of the stop wall 655 is engaged. The contact of the rear surface 4212 of the mating convex portion 420 prevents the male member 500 from being pulled back from the female member 600.

  As shown in FIGS. 11 and 12, after the male member 500 is inserted into the female member 600, the operating body 400 can pivot about the distal end side of the operating body 400. The operating body 400 is separated from the insertion portion 210 side of the male member main body 200 from the first position shown in FIG. 12 adjacent to the insertion portion 210 side of the male member main body 200 in accordance with the elasticity of the leaf spring 300 than the first position. It is possible to return to the second position shown in FIG.

  The leaf spring 300 is more compressed when shown in FIG. 12 than when shown in FIG. The distance between the first flat plate portion 310 and the second flat plate portion 320 of the leaf spring 300 when the operating body 400 is in the first position is the first flat plate portion 310 of the leaf spring 300 when the operating body 400 is in the second position. And the distance between the second flat plate portions 320 is narrower.

  When the operating body 400 is pushed downward to change from the state shown in FIG. 11A to the state shown in FIG. 12A, the claw 450 provided on the lower surface of the operating body 400 causes the vertical groove portion 252 of the male member main body 200. The rear surface 4501 of the claw 450 comes into contact with the rear side surface 25 of the longitudinal groove portion 252. Therefore, even if the operating body 400 is pushed backward in a state where the operating body 400 is pushed down, the claw 450 comes into contact with the rear side surface 25 of the longitudinal groove portion 252 and further rearward movement is prevented.

  When the operation body 400 is pushed downward to change from the state shown in FIG. 11C to the state shown in FIG. 12C, the engagement convex portion 420 is pushed down and engaged with the stop wall 655. The engaging projection 420 is disengaged from the stop wall 655. When the operating body 400 is pushed backward at the time shown in FIG. 11C, the engagement convex portion 420 can move backward beyond the stop wall 655, unlocking is performed, and the female member 600 is moved from the female member 600 to the male member 500. Can be pulled out and uncoupled.

  In the present embodiment, a portion to be engaged with the stop wall 655 of the female member 600 is provided not on the operation convex portion 410 but on the engaging convex portion 420 positioned below the operation convex portion 410, and the peripheral wall portion of the female member 600 is provided. A notch 630 capable of receiving the operation convex portion 410 is provided at 640. According to this configuration, it is the engaging convex portion 420, not the operating convex portion 410, that is required to advance beyond the stop wall 655 of the peripheral wall portion 640 of the female member 600 to the back side of the peripheral wall portion 64. Therefore, the vertical width of the inlet 620 of the peripheral wall portion 640 of the female member 600 can be secured narrow, and the thinning of the buckle 100 can be effectively promoted.

  Furthermore, in the present embodiment, the operation body 400 can be pivoted around the pivot axis on the distal end side of the operation body 400, and the operation of pulling out the male member 500 from the female member 600 can be facilitated. Furthermore, in this embodiment, the operation body arrangement | positioning recessed part 20 can be provided in the insertion part 210 of the male member 500, and the operation body 400 can be arrange | positioned in the operation body arrangement | positioning recessed part 20, and further thickness reduction can be promoted.

  The first flat plate portion 310 of the leaf spring 300 is accommodated by the leaf spring accommodating portion 411 of the operating body 400, and the second flat plate portion 320 of the leaf spring 300 is positionally regulated by the positioning structure of the insertion portion 210, and finally the vertical groove portion 252. The Thereby, the assembly of the male member 500 can be facilitated, and the positional stability of the leaf spring 300 after the assembly can be ensured.

  Further, in the present embodiment, a guide protrusion 260 for guiding the second flat plate portion 320 of the leaf spring 300 to the vertical groove portion 252 is provided. Even if it is difficult to visually recognize the leaf spring 300 accommodated by the leaf spring accommodating portion 411, the second flat plate portion 320 of the leaf spring 300 can be more reliably guided to the longitudinal groove portion 252.

  In this example, the left engagement protrusion 421 and the right engagement protrusion 422 are provided on the left and right of the operation protrusion 410, but only one of them may be provided. Further, the position at which the stop wall 655 and the engaging projection 420 are provided is arbitrary. For example, the stop wall 655 may be provided at a position away from the inlet 620 of the female member 600, or may be a place other than this.
