Claims

[Scope of Claim for Utility Model Registration] (1) In a shaft regulating member that regulates the axial position by engaging with a slit groove provided on the outer peripheral surface of the shaft, a center that functions as a shaft insertion guide. A shaft characterized in that the outlet end of the hole forming part is configured to be elastically deformable in the radial direction, and the outlet end is provided with a plurality of engaging protrusions along the circumferential direction that can engage with the slit groove. Regulation material for use. (2) The shaft regulating member according to claim 1, wherein an outer circumferential portion is formed outside the central hole forming portion via a ring-shaped groove. (3) The shaft regulating member according to claim 1 or 2, wherein the outer circumferential portion functions as a pulley, gear, or other rotational force transmitting means. (4) Utility model registration claims 1 to 3, in which the outlet end of the central hole forming portion is split along the axial direction or formed into a comb-like shape to facilitate diameter expansion and/or diameter reduction. The shaft regulating member described in any one of the preceding paragraphs. (5) Any shaft having a polygonal cross-sectional shape, an elliptical cross-sectional shape, or a notched surface where a part of the circular cross-sectional shape is cut along the axial direction so that the center hole forming part corresponds to the shape of the shaft-side insertion part. The shaft regulating member according to any one of claims 1 to 4, which is configured so as to be rotatable integrally with the shaft by forming a shaft. (5) Utility model registration claim 1, wherein the center hole forming part is formed to have a circular cross-sectional shape corresponding to the shape of the shaft side insertion part, so that it can rotate freely with respect to the shaft. The shaft regulating member according to any one of paragraphs 1 to 4.
