Japanese Patent JP2019165555
Kind Code:
A
Abstract:
To provide a gear unit capable of obtaining good assembling performance while preventing generation of abnormal noise caused by clearance between a shaft and a gear member.SOLUTION: A gear unit comprises: a shaft 16; a gear member 18 rotatably supported by the shaft 16; and a regulating structure 42 for regulating relative displacement of the gear member 18 and the shaft 16 in a radial direction. The regulating structure 42 is constituted by a single elastic member 44 arranged in an elastically deformed state between the gear member 18 and the shaft 16. Compared with a case where the restriction structure 42 is composed of a plurality of members, the number of components of the gear unit 10 can be reduced. Thus, man-hours required for assembling the gear unit 10 can be reduced, and good assembling performance can be obtained.SELECTED DRAWING: Figure 5
