As a result, the male member 1 and the female member 2 can be rotated in the direction around the insertion center axis x in a state where the head 10 of the male member 1 does not come out in the insertion direction into the hollow leg 21. They are put together and come to be combined.

  Further, in this embodiment, the male member 1 can be biased in such a direction that the lower part of the head 10 of the male member 1 is pressed against the upper part 21g of the inner collar part 21f of the female member 2 against the female member 2. The urging means is provided. In the example shown in the figure, one end of each of the through holes 20a of the female member 2 is integrally connected to the hole edge portion of the hole portion of the through hole 20a and directly above the upper end of the elastic engagement piece 21b. An elastic protruding piece 20b protruding toward the center is provided. A space is formed between the protruding ends 20c of the pair of elastic protruding pieces 20b and 20b so that the tip of the pin member 3 can be accommodated, and the protruding ends 20c of the elastic protruding pieces 20b protrude downward. A protrusion 20d is formed. When the male member 1 head 10 is introduced into the hollow leg 21 of the female member 2, the upper portion of the head 10 of the male member 1 abuts against the protrusion 20d of the elastic protrusion 20b, and this elastic protrusion 20b is The head 10 of the male member 1 is introduced into the hollow leg 21 up to a position where the lower part 10c of the outer collar part 10b is positioned on the upper part 21g of the inner collar part 21f while being bent upward. It has become. That is, in this embodiment, the elastic protruding piece 20b functions as the urging means.

  And in this embodiment, the leg 11 of the male member 1 is engaged with the hollow leg 21 of the female member 2 and the head 10 of the male member 1 in the through hole P1a of the first member P1, The hollow leg 21 is twisted or relatively twisted by a predetermined angle from the state in which the hollow leg 21 of the female member 2 is engaged with the through hole of the second member P2. Cam means for moving the male member 1 in a direction in which the head portion 10 of the male member 1 is drawn is provided.

  In the illustrated example, the lower surface 10c of the outer flange portion 10b of the head portion 10 of the male member 1 has an inclined surface 10e that gradually increases toward the center 10d of the outer flange portion 10b in the direction around the insertion central axis x. They are formed on both sides of the center 10d. Each of the inclined surfaces 10e and 10e is a surface substantially orthogonal to the insertion center axis x, and is formed along a spiral (not shown) that goes around the insertion center axis x. In the illustrated example, the inclined surface 10e constitutes the sliding portion 10f constituting the cam means.

  On the other hand, the upper surface 21g of the inner flange portion 21f of the hollow leg portion 21 of the female member 2 has an inclined surface 21i that gradually increases toward the center 21h of the inner flange portion 21f in the direction around the insertion center axis x. They are formed on both sides of 21h. Each inclined surface 21i is a surface substantially orthogonal to the insertion center axis x, and is formed along a spiral (not shown) around the insertion center axis x. In the illustrated example, the inclined surface 21i constitutes a cam surface 21j constituting the cam means.

  In the illustrated example, the lower portion 10c of the outer flange portion 10b of the head portion 10 of the male member 1 has a valley shape, and the upper portion 21g of the inner flange portion 21f of the hollow leg portion 21 of the female member 2 is complementary to the lower portion 10c. It has a mountain shape that is related. That is, after introducing the head 10 of the male member 1 into the hollow leg portion 21 of the female member 2 as described above, the lower portion 10c of the outer flange portion 10b is positioned on the upper portion 21g of the inner flange portion 21f. Thus, when the male member 1 is twisted by a predetermined angle or relatively twisted, the hollow of the female member 2 having a mountain shape is formed in the lower portion 10c of the outer flange portion 10b of the head portion 10 of the male member 1 having a valley shape. The upper portion 21g of the inner flange portion 21f of the leg portion 21 is accommodated, and the lower portion 10c and the upper portion 21g are combined in a state where the inclined surfaces 10e and 21i are aligned. The male member 1 is slightly moved upward by the sliding contact of the sliding portion 10f with the cam surface 21j in the process of the twisting operation, and the upward bending of the elastic protruding piece 20b occurs. A position where the upper portion 21g of the inner flange portion 21f of the hollow leg portion 21 of the female member 2 having a mountain shape completely fits in the lower portion 10c of the outer flange portion 10b of the head portion 10 of the male member 1 having a valley shape (hereinafter referred to as this position). When the twisting operation is performed until the male member 1 is in the set state), the elastic protruding piece 20b is elastically restored. Thereby, the combined state of the male member 1 and the female member 2 is maintained. In the illustrated example, in the set state, the protrusion 20d of the elastic protruding piece 20b of the female member 2 is accommodated in the engaging recess 10h of the head 10 of the male member 1, and this set state is more stable. Can be maintained.

  By inserting and engaging the leg 11 of the male member 1 into the through hole P1a of the first member P1, from the state where the hollow leg 21 of the female member 2 is inserted and engaged with the through hole P2a of the second member P2, The first member P1 and the second member P2 are connected via the clip. In the illustrated example, the insertion of the hollow leg portion 21 of the female member 2 into the through hole P2a of the second member P2 is permitted by the inward bending of the pair of elastic engagement pieces 21b and 21b. The elastic engagement piece 21b is repelled at the position where the hollow leg portion 21 is completely inserted into the through hole P2a of the member P2, and the second portion between the head 20 of the female member 2 and the protrusion 21c of the elastic engagement piece 21b. The female member 2 is engaged with the second member P2 with the member P2 interposed therebetween. (FIG. 9) On the other hand, the insertion of the leg portion 11 of the male member 1 into the through hole P1a of the first member P1 is permitted by the inward bending of the pair of elastic leg pieces 11a, 11a. The hollow leg 21 of the female member 2 and the elastic leg piece 11a are engaged by the spring of the pair of elastic leg pieces 11a, 11a at the position where the leg part 11 of the male member 1 is completely inserted into the through hole P1a of the member P1. The clip is engaged with the first member P1 with the first member P1 sandwiched between the surface 11d. (FIG. 10) From this connected state (FIG. 12), when the second member P2 is twisted or relatively operated around the insertion center axis x, (FIG. 13) the male member 1 is driven by the cam means. Is moved in a direction in which the head 10 of the male member 1 is pulled into the hollow leg 21 of the female member 2. In the illustrated example, even if the second member P2 is twisted in either the forward or reverse direction around the insertion center axis x from the set state (FIG. 14), the hollow leg portion 21 of the female member 2 having a mountain shape is formed. The sliding surface 10f of the lower portion 10c of the outer flange portion 10b of the head portion 10 of the male member 1 is guided to the cam surface 21j (inclined surface 21i) of the upper portion 21g of the inner flange portion 21f of the male member 1 in the direction of ascending the mountain. 1 is moved a little in the direction of entering the hollow leg 21 as a whole. (FIG. 15) At this time, the elastic protrusion 20b of the female member 2 is elastically deformed so that the protrusion 20d is pulled out from the engaging recess 10h of the head 10 of the male member 1. By the movement of the male member 1, the engaging position of the leg portion 11 of the male member 1 with respect to the first member P1 approaches the second member P2, and thereby the first member P1 and the second member P2 are brought into close contact with each other. .

  The pin member 3 has a head 32 formed at one end of the shaft body 31, and the other end of the shaft body 31 serves as the tip 30 of the pin member 3. The shaft body 31 is configured to have a thickness substantially equal to the distance between the inner surfaces of the pair of elastic leg pieces 11a and 11a constituting the leg portion 11 of the male member 1. The pin member 3 has its distal end 30 side inserted into the female member 2 through the through hole 20a of the head 20 of the female member 2, and the side portion on the distal end 30 side is a pair of elastic protruding pieces 20b of the female member 2. , 20b are connected to one protruding end 20c via a breakable portion 33 so that the central axis of the shaft body 31 is integrated with the female member 2 so as to be substantially along the insertion central axis x. In the illustrated example, the pin member 3 is moved to the insertion center axis x from the state in which the leg portion 11 of the male member 1 is inserted and engaged with the through hole P1a of the first member P1 using the head 32 of the pin member 3. When pushed in the direction, the breakable portion 33 is broken so that the pin member 3 is separated from the female member 2 and pushed into the leg portion 11 of the male member 1 through the through hole 10a of the head 10 of the male member 1. It has become. By pushing the pin member 3, the pair of elastic leg pieces 11a, 11a constituting the leg portion 11 of the male member 1 is made rigid, and the engagement state of the male member 1 with the first member P1 becomes strong. (FIG. 11) The head 32 of the pin member 3 has a size that enters the through hole 20a of the head 20 of the female member 2, but does not enter the through hole 10a of the head 10 of the male member 1. . The protruding end 20c of the elastic projecting piece 20b connected by the breakable portion 33 in the pushing process hits the head 32 of the pin member 3, and the pushing of the pin member 3 after the contact is made by the elastic projecting piece. A pinned member 32a is formed which is allowed by elastic deformation of 20b, and receives protrusion from above at the protruding end 20c of the elastic protruding piece 20b due to the elastic protrusion 20b at the end of pushing. The state where 3 is pushed in is also stably maintained. In the illustrated example, the twisting or relative twisting operation of the second member P2 causes the head 32 of the pin member 3 pushed in as described above to the small protrusion 10g of the male member 1. It is regulated at the position where it hits. (Fig. 15)

  The above-described imparting of the property to the portion to be provided with the elastic deformation property in the clip can be easily ensured by using the clip as a synthetic resin molded product.
