Title:
SHAFT HOLE STRUCTURE FOR RESIN ROTATION TRANSMISSION MEMBER
Document Type and Number:
WIPO Patent Application WO/2018/116927
Kind Code:
A1
Abstract:
Provided is a shaft hole structure for a resin rotation transmission member, the structure being capable of preventing occurrences of collision noise and occurrences of rotation transmission errors caused by a fitting portion rattling against a rotation transmission shaft. A shaft-side flat face extending along the axial direction is formed on the rotation transmission shaft on a shaft end fitted in a shaft hole (4) of a resin rotation transmission member (1). A hole-side flat face (13) is formed on the shaft hole (4) of the resin rotation transmission member (1) to face the shaft-side flat face of the rotation transmission shaft. The hole-side flat face (13) is formed so that a linear projection (17) that is deformed by the shaft end extends along the fitting direction for the shaft end when the shaft end is fitted into the shaft hole (4). The projection height of the distal end of the linear projection (17) on the side where the shaft end is inserted into the shaft hole (4) increases gradually along the fitting direction for the shaft. In addition, the deformed linear projection (17) partially fills the space between the hole-side flat face (13) and the shaft-side flat face.
