Further, the third pressing portion 103 is deformed into a shape in which the engaging piece 93 is inclined downward toward the front end side of the main body 20. Thereby, the third pressing portion 103 is deformed so as to press the flange 80A of the cover member 50 from above, and is deformed so as to block the entrance of the fitting groove 90. Further, the third pressing portion 103 is such that the upper and lower dimensions of the entrance of the fitting groove 90 are smaller than the thickness of the upper and lower sides of the flange 80A of the cover member 50, thereby blocking the entrance of the fitting groove 90.

Further, as shown in FIG. 3, the third pressing portion 103 is formed in a substantially triangular shape in plan view, and is formed at the boundary between the upper surface of the upper surface of the flap 21 and the third pressing portion 103 on the main body 20. 3 The ridge line portion 103a of the starting point of the downward inclination of the pressing portion 103. Further, the ridge line portions 103a of the left and right third pressing portions 103 are intersected at an angle α of 90 to 110 degrees with respect to the extension line of each ridge portion 103a, and are gradually separated as they are directed toward the front of the main body 20. Thereby, the third pressing portion 103 is formed such that the width dimension thereof in the left-right direction gradually increases toward the front of the main body 20.

Next, the procedure for attaching the tab 15 to the slider 10 for the slide fastener will be described with reference to Figs. 10 to 13 .

First, as shown in FIG. 10, since the shaft portion 15a of the pull-tab 15 is pressed into the insertion gap S from the rear to the front, the opening and closing member 60 is slid to the front, and the shaft portion 15a of the pull-tab 15 enters the cover member 50. As shown in FIG. 11, the opening and closing member 60 slides to the rear, and the shaft portion 15a of the pull tab 15 enters the valley portion 63 between the first and second lock portions 61, 62 of the closing member 60.

Then, as shown in FIG. 12, since the shaft portion 15a of the pull tab 15 is inserted into the gap S and pushed forward, the opening and closing member 60 slides to the front, and the shaft portion 15a of the pull tab 15 lifts the lock member 40 upward. The square portion is pushed up into the handle accommodating portion 56 of the cover member 50, and as shown in FIG. 13, the opening and closing member 60 is slid to the rear, and the shaft portion 15a of the pull tab 15 is received in the movable recess 44 of the lock member 40. .

As described above, according to the slider 10 for a slide fastener of the present embodiment, the cover member 50 is attached to the fitting groove 90 of the upper blade 21 by the flange 80A, and the side panel 52 of the cover member 50 is provided. The first compression is pressed against the column portion 31 The first pressing portion 101 that is pressed by the recessed portion 31c, the second pressing portion 102 that presses the raised portion 93a of the engaging piece 93 of the upper blade 21 with respect to the second pressing recessed portion 81a of the first flange 81, And the third pressing portion 103 which is pressed against the front end portion of the engaging piece 93 of the upper blade 21 by the inlet of the fitting groove 90 is fixed to the upper blade 21, so that the cover member 50 can be lifted. The strength is fixed so that the falling of the cover member 50 can be prevented.
