  The portion near the end 42a of the second handle 42 has a large window portion 26 as in the case of the first handle 16, and the thin portion between the window portion 26 and the end portion 42a is a cylindrical thin portion. A shaft portion 28 is formed. As shown in FIGS. 2 and 5, when the second puller 42 is tilted to the front side of the body 14, the surface located on the opposite side of the body 14 is the surface 42 c, and the surface 42 c side is the first puller 16. Connected in layers. The surface 42c of the first handle 16 is a portion close to the end portion 42b opposite to the end portion 42a and faces the protrusion receiving portion 32 of the socket member 30 in a state of being overlapped with the first handle 16. The plug protrusion 44 is integrally provided at the position.

  The plug protrusion 44 is a cylinder protruding substantially perpendicularly from the surface 42c, and the height from the surface 42c is from the end face 32b of the protrusion receiving portion 32 of the socket member 30 when it is superimposed on the first handle 16.

The depth of the recess 48 is a depth that allows a slight margin when the contact protrusion 40 of the first handle 16 is inserted when the recess 48 is overlaid on the first handle 16. The bottom portion and the inner peripheral surface of the recess 48 are smoothly continuous. Both end portions 48b in the longitudinal direction of the concave portion 48 reach the vicinity of the side edge portions in the width direction of the surface 42c, become shallower as they approach the both end portions 48b, and reach the surface 42c.

  The body 14 and the handle attachment portion 18 of the second slide fastener slider 11 have the same structure as the first slide fastener slider 10.

  Next, a manufacturing method of the first slide fastener slider 10 will be described. The first handle 16 of the slider 10 for the first slide fastener is formed by first die-casting the handle body 19 and made of a hard metal such as zinc alloy or aluminum alloy. A separate socket member 30 is attached to the pulling body 19 integrally formed by die casting by caulking to form the first pulling handle 16.

  As shown in FIG. 8, the pulling body 19 is provided with a mounting surface 50, which is a circular flat surface having substantially the same size as the socket member 30, in the vicinity of the end portion 16 b on the surface 16 c. The attachment surface 50 is integrally provided with five claw portions 52 along a concentric circle having a diameter smaller than that of the attachment surface 50. The claw portion 52 is a plate body that protrudes substantially perpendicular to the mounting surface 50 and has a thickness in the diameter direction. The width along the circumferential direction gradually decreases upward, and the tip 52a is sharp. . In addition, although the number of the nail | claw parts 52 of a present Example is five, the number of the nail | claw parts 52 is not limited to this Example.

  The socket member 30 is attached by inserting the claw portion 52 into the curved outer peripheral portion 34b from the opening 38 on the back side of the socket member 30 and pressurizing in a direction approaching each other. As a result, the claw portion 52 is plastically deformed and crimped radially outward along the inner side of the curved outer peripheral portion 34b of the socket member 30, and the socket member 30 is fixed to the mounting surface 50 as shown in FIGS. Is done. The socket member 30 is attached to form the first handle 16, and the first handle 16 is attached to the handle attachment portion 18 of the body 14 by a predetermined method to form the first slide fastener slider 10.

  Next, a method for manufacturing the second slide fastener slider 11 will be described. The second handle 42 of the second slide fastener slider 11 is also formed by die casting in the same manner as the handle main body 19 and is made of a hard metal such as a zinc alloy or an aluminum alloy. The plug protrusion 44 is also integrally formed. Then, similarly to the first puller 16, the second puller 42 is attached to the puller attachment portion 18 of the body 14 by a predetermined method, and the second slide fastener slider 11 is obtained.

  Next, the engaging operation of the first handle 16 and the second handle 42 will be described. As shown in FIG. 5, the first puller 16 and the second puller 42 are aligned in the longitudinal direction, with the end 16a aligned with the end 42a and the end 16b aligned with the end 42b. The surface 16 c of the handle 16 and the surface 42 c of the second handle 42 face each other, and the plug projection 44 of the second handle 42 is inserted into the projection receiving portion 32 of the socket member 30 of the first handle 16. The head 44b of the plug projection 44 is larger than the inner diameter of the end face portion 32b of the projection receiving portion 32 and does not pass through it. However, when pressed with a strong force, the projection receiving portion 32 is elastically deformed outward and the slit 36 is pressed. Is opened, the inner diameter of the end surface portion 32b is increased, and the head portion 44b can pass therethrough. After the head 44b passes, the elastic deformation of the projection receiving part 32 is restored, the end face 32b abuts on the neck 44a of the plug projection 44, and the head 44b cannot pass. Thereby, the plug protrusion 44 is locked inside the protrusion receiving part 32, and the first puller 16 and the second puller 42 are engaged. The small protrusion 46 of the second puller 42 abuts in the vicinity of the end 16 b lower than the socket member 30 of the first puller 16, and the abutment protrusion 40 of the first puller 16 is the recess 48 of the second puller 42. Will not interfere with engagement.

  When the engagement between the first puller 16 and the second puller 42 is released, the first puller 16 and the second puller 42 are easily separated by following the reverse of the above-described steps.
