Claims

[Claims for Utility Model Registration] 1. A hollow shaft made of synthetic resin with a flat surface formed on a part of the outer peripheral surface of the tip and a gear at the rear end; a metal hollow screw that is fitted into the hollow screw and has a threaded portion and a flat surface on its outer circumferential surface; a pointer that is non-rotatably attached to the hollow screw; and a pointer fixing nut that is screwed onto the hollow screw. A pointer mounting structure for watches, etc., consisting of and . 2. In claim 1 of the utility model registration claim, the hollow shaft consists of a front hollow shaft having a flat surface on a part of the outer peripheral surface of the tip, and a rear hollow shaft connected to this. A pointer mounting structure for watches, etc. that has a gear at the rear end of the shaft. 3. A pointer mounting structure for a watch, etc., in which the gear is connected to a hollow shaft via a slip mechanism, as set forth in claim 1 or 2 of the utility model registration claim. 4. A pointer mounting structure for a watch, etc., in which a small protrusion for preventing a hollow screw from coming off is provided on a flat surface of a hollow shaft, as set forth in claim 1 or 2 of the utility model registration claim.
