PURPOSE:To facilitate assembly and to improve strength by composing a handle of a lock part for relative rotation prevention which engages a handle shaft having a lock and a notch part in the external circumferential surface, and a handle-side member which has a relative extraction preventing means. CONSTITUTION:In a handle 140, an axially prismatic hollow part 140a and a cap hole are formed. An intermediate member 440 has a serrated part 440a corresponding to the serrated part 230 of a handle shaft 230, a shoulder part 440b corresponding a notch groove part 230b, shoulder parts 440c and 440d for limiting the axial motion of the intermediate member 440, a projection part 440e atop, and a slit 440f for allowing the intermediate member 440 to flex in a radius direction. A cap 340 has an opening part 340a wherein the projection part 440e is fitted. Consequently, the product is strong and easy to attach and detach. |
