PROBLEM TO BE SOLVED: To increase the strength of a slider shell, the ease with which a pull is gripped, and the smoothness of operations. SOLUTION: A projecting surface 12 which projects from the surface of a slider shell 1 is provided around the bases of the pair of pull mounting poles 11 provided on the top surface of the upper wing plate 6 of the slider shell 1, to reinforce the upper wing plate 6 and the mounting poles 11. A pull 2 pivotally attached between the mounting poles 11 is made to abut to the projecting surface 12 as it turns about a pivot 21, and a recessed surface 23 which can accommodate the projecting surface 12 is formed, with each side of the handle 20 of the pull 2 thickly formed to facilitate gripping, allowing a smooth slider operation even if the user wears gloves during the winter. |
