Title:
FRICTION DRIVE MECHANISM AND GEARED MOTOR
Document Type and Number:
Japanese Patent JP2021081024
Kind Code:
A
Abstract:
To provide a friction drive mechanism capable of suppressing variation of frictional force acting between a plate-like member and a gear member, even when a flat surface for stopping rotation of the plate-like member to a rotating shaft, is formed on the rotating shaft.SOLUTION: In a friction drive mechanism 17, a rotating shaft 12 is provided with an insertion portion 12b inserted to a gear member 14 and a plate-like member 15, and a planar supporting surface 12e orthogonal to an axial direction of the rotating shaft 12, and an outer peripheral face of the insertion portion 12b is provided with a flat surface 12d for stopping rotation of the plate-like member 15 to the rotating shaft 12. At least at a part on which the flat surface 12d is formed in a circumferential direction of the rotating shaft 12, a recessed portion 12f recessed toward a Z1 direction side, is formed on the supporting surface 12e with which the plate-like member 15 is kept into contact with a prescribed pressure, and a side face of the recessed portion 12f is disposed on the same plane as the flat surface 12d.SELECTED DRAWING: Figure 4
