The inner circumferential surface 24a of the buckle arm hole 24 of the first and second fingers 22 is formed, and a pair of buckle arm insertion holes SH are described, and the pair of buckles are inserted in the state in which the male member 2 is inserted into the female member 3 The buckle arm holes 24 of the arms 22 are exposed to two cows = two horns, and one of the two sides of the female member 3 passes through the holes of the buckle arms: they are each occupied. Accordingly, the shape of the inner peripheral surface 24a of the buckle arm hole 24 and the shape of the opening and the curved surface of the hole are the same (refer to the first = first figure). In the case of the yoke, the male member 2 and the female member 3 are buckled to form a buckle. Ι ϊΐ ϊΐ 整体 整体 整体 整体 整体 整体 整体 整体 整体 整体 整体 整体 整体 整体 整体 整体 整体 整体 整体 整体 整体 整体 整体 整体 整体 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 The center of the inner portion of the female member 3 is formed with a partition wall extending in the insertion direction. The center of the front side thin guide groove 36 in the left-right direction is connected to the center of the back surface member f. By dividing the wall 38 by this, the internal space S of the two pieces 3 is divided into two chambers at the same time. It is also possible to exert the heart = to prevent the upper wall 31 and the lower wall 32 of the female member 3 from being 2 201200056 μ ^, on the other hand, the insertion side connecting wall 40P, which is inserted opposite to the pair of engaging ends 4 2R, 2L The end portions 3R and 3L are formed with right side and left side fitting recesses 40PR and 40PL which are recessed inwardly in the insertion direction, and are recessed from the end of the insertion side far f wall 40P toward the inner side of the guide surface 4〇1. This concave war is perpendicular to the direction of the two sides, that is, from the side, it is fine: it conforms to the shape of the inlaid cams 21R, 21L, in other words, the outer surfaces of the left recess 4GPR, 4GPL are each The face-shaped end faces 3RE, 3LE which are recessed in the direction of insertion are formed. In this way, the end faces of the engaging end portions 2R, 2 2RS, 2LS and the insertion end portions 3R, 3L are similar, that is, the private octahedron and the fitting recessed portion 4〇PR and the facet of the 槪 are complementary to each other in the second direction. Consistent shape. Therefore, when the male member 2 and the female member 3 are coupled to each other, the 21R is inserted into the right fitting recess 4〇PR β, and the left fitting convex portion is inserted into the left visceral concave portion 4GPL, thereby making the curved contact easy. Chimerism. Thus: 面ί, the outer surface of the insertion side joint wall 40ρ is joined to the outer surface of the base body 21 of the male member 2 to form a smooth surface of the seam. Further, a belt fixing portion 39 for fixing the flat belt of the connecting buckle i is provided at the insertion end of the female member 3, and three bottomed holes are formed in the bottom surface of the belt fixing portion 39 for the buckle. Further, as shown in the seventh diagrams (a) and (b), when one of the male members 2 is paired with D a and the square is inserted into the insertion opening 3P, the outer side of the front end of the buckle arm 22 is first and the 'female structure ^ 3 The guiding surface 40Pa is contacted and guided forward, so that the = end can enter the inside of the female member 3; then, the positive side of the buckle arm 22 is replaced by the positive side of the front side, and the front side is inserted into the groove. At the same time, one of the rear sides of the buckle f 22 is guided to the open port 3D. At this time, since the buckles on the outer sides of the pair of buckles f 22 are formed in a shape that bulges toward the left and right sides, and a pair is inserted; the guide surface forms the base end of the just-and-forward arm 22, , a pair of buckle arms 22 - inserted into the female member 3 13 201200056, the side outer side surface, that is, the thin guide surface · a forced continent to guide the amount of swell outward from the guide surface 40Pa, thus, the arm Carding Qiu =

When the position of the 4GPa is... the buckle arm 22 is forced to phase I; the deflection is made, but once the buckle arm locking portion 22S passes the guide surface a ^ ί, the surface 4〇Pa is released to the buckle arm locking portion 22S. Bet, -U

The ϊ ϊΐ 变形 deformation is followed by the front side insertion groove 36a and the back side side U being guided to gradually progress. Here, since the width of each groove of the inner side guide groove 37 on the front side is gradually narrowed from the ratio of the inserted population 3p (10), the button arm 22 continues to guide the deep inner material ^ and the rear side inner guide groove 37. The pair of buckles are turned to the center portion in the left-right direction, that is, deeper inside than the inside of the female member 3 at a predetermined ratio. According to this configuration, when the buckle arm locking portion passes through the guide surface 4〇Pa, it is applied to the outside of the buckle arm 22. When the fortune! 22 continues to be inserted into the female member 3, the front convex portion now has the back convex portion. 23B arrives at the open port 3d. At this time, the 32S system first expands at the terminal insertion slot 36a of the front side and the card edge It = the end of the guide slot 37 is expanded, which is originally one of the relative inward deflections ΐί i = body The elastic restoring force is opened along the shape of the locking groove and the outside. Then, the front convex portion 23F is engaged with the card. The front convex portion 2 is blocked from being sweated, and it is difficult to insert the back surface convex portion 23B into the bottom edge of the insertion edge 32S. In the eighth figure, the pair of fitting convex pools, the two rivers, and the pair of embedded structures are purely detailed, that is, after the combination of the female members 3, the upper surface of the upper wall 31 is viewed from above. At the time, the conversation of the joint portion is explained by the fact that the buckle arm 22 reads the convex portion 21R and fills the shadow. 201200056 As shown in the eighth (8) and (b), in the present embodiment, when the buckle 1 is viewed from the top surface of the upper wall 31, the engaging portion of the male member 2 and the female member 3 is inserted in the insertion direction. The maximum gap is the interval t1. This interval t1 corresponds to the movement of the front convex portion 23F and the locking groove 36S in the insertion direction of the buckle i in the engaged state, or the clearance of the rear convex portion 23B and the locking edge 32S in the insertion direction. Quantity (loose amount). The eighth diagram (a) shows that the amount of play of the front convex portion 23F and the locking groove 36S in the insertion direction is equal to the interval t1. As for the divisional left and right fitting recesses 40PR, 40PL, the left and right fitting projections 21R, and the section of the melon (i.e., the insertion amount is formed larger than the interval (i.e., the amount of play) t1. On the one hand, from the upper wall 31 The width (end surface width) 4〇PLW of the left-side insertion end portion 3 in the left-right direction is substantially equal to the width (end surface width) 21LW of the left-side engagement end portion 2l in the right side view; similarly, from the upper wall The width direction width 40PRW of the right insertion end portion 3R in the right direction is substantially equal to the surface width 21RW of the right side engagement end portion 2R in a plan view. Further, although not shown, the width in the left-right direction of the left-hand masonry end 3L is substantially equal to the width in the left-right direction of the left-hand articulation 2L from the positive side of the lower wall %; similarly, the right insertion end portion 3R The width in the left-right direction is substantially equal to the width in the left-right direction of the right-hand engaging end portion 2R. The width of the left side end face 21LW is defined by the width of the base end of the left side buckle arm 22, and the width of the right side end face 21 RW is the width of the base end of the right side buckle arm 22 and the width of the right side fitting convex portion. Limited. Further, the end face width 2黯 and the end face width 2A are the same width, so the 'end face width 40PLW and the end face width 4〇PRW are also wide='from positive, to the upper side of the upper wall 31 and the lower wall 32=, : The gap between the 2:/σ insertion direction and the original visible gap is often obscured by the base end of each buckle I 22 and the left and right plate joint projections 21R and melon. As described in detail above, according to the buckle of the present embodiment, the following effects can be obtained: (1) The surface of the fitting convex portion 21R and the surface of the fitting concave portion 4〇pR are fitted by the phase 15 201200056 end edge 2RE, 3RE And the pair of end faces 2R£, 3R£ ϊίΓίίί ' at the same time, the surface of the fitting convex portion 21L and the fitting concave are in the direction of the insertion direction. According to this configuration, the insertion portion of the end portion 2R, 2L is inserted, as viewed from the plane directly above the plane containing the end faces f, and the end portions 3R, 3L are inserted.

2^ 2^^ 2R . 2L Substitute landfill' In other words, from the end face 2RE, 3RE, the top side of the face, the insertion end 3R, 3L of the joint part can be seen through the part Since the end faces are concealed, it is possible to improve the smoothness and the integrated feeling of the entire surface of the male member 2 and the female member 3. (J) The step in which the fitting convex portions 2m and 21L have the insertion direction is larger than the gap between the interconnecting members 3R and 3L and the engaging end portions 2R and 2L. According to this, the area of the front end edge 2RE and the end edge 3RE ^, and the end edge 2LE and the end edge 3LE, when the flat side of the plane of the end face 2RE, 3RE, 3LE is directly above the head IL = the joint portion of the member 3 The overlapping regions are larger than the gap between the j portions 3R, 3L and the engaging end portions 2R, 2L. Therefore, when the joint between the male member 2 and the female member 3 is viewed from the plane of the face 2RE, the face, and the face of the 3LE, the gap between the insertion end portions 3R and 3 is just the edge of the end face that is fitted to each other. The shadow is not worn, so that the male member 2 and the female member 3 can be added to the sense of body and high sense. θ (3) has the end faces 3RE and 3LE of the enemy recesses 40PR, 40PL forming a concave step which is concavely concave in the insertion direction, and the end edges 2RE and 2LE having the fitting projections 2ir and BE are formed in the insertion direction. The convex shape of the pointed protrusion is poor. According to this configuration, when the male member 2 and the female member 3 are fastened, the end faces of the insertion end portions 3R and 3L can be applied by the engagement of the wedge-shaped concave portion and the convex portion difference.

The fitting of the end faces 2RE and 2LE of the connecting portions 2R and 2L is smoother and smoother, and the side faces 3RS and 3LS of the insertion end portions 3R and 3L and the engaging end portions 2R and 2L 201200056 = although each has a step difference. However, the insertion and engagement of the male member 2 and the female member 3 can be smoothly and smoothly performed. (4) The gap between the insertion end portions 3R, 3L and the engaging end portions 2R, 2L is covered by the step difference between the mutually = 4GPR, 4GPL and the fitting convex portions 21R, 21L. Forming a door gap 2LS extending from the base end of the buckle arm 22 to the engaging end portions 2R, 2L, the base end of the insertion end portions 3R, 3L and the connecting end portions 2R, 2L Ϊ j 22糸 to the engaging end portions 2R, 2L The outer side surface 2RS and the outer space of the first one can be completely covered by the step difference, so that the body part 2 and the female member 3 can be combined.
