Title:
ELASTIC BODY AND CLUTCH DEVICE HAVING THE ELASTIC BODY
Document Type and Number:
Japanese Patent JP2019113132
Kind Code:
A
Abstract:
To provide an elastic body capable of elastically supporting an enclosure while preventing the enclosure from inclining with respect to a body of rotation and providing a clutch device capable of locally changing the locus gap between an outer race and an inner race by applying a radial load while restricting or preventing the outer race from inclining with respect to an inner shaft and downsizing in the axial direction.SOLUTION: An elastic body 25 integrally comprises: a cylindrical part 41 externally fitted to an inner cylinder 31 of the outer race 21; and a plurality of projections 42 spaced in a circumferential direction Y and protruding from the cylindrical part 41 toward the outside in a radial direction Z. Each protrusion 42 has a cantilever shape extending along the circumferential direction Y and is bent so as to be convex outward in the radial direction Z. Each projection 42 is in sliding contact with the inner periphery of a cylindrical body 34 of an inner race 34 and includes: an outer end edge 42a extending along the axial direction X; and a tip edge 42b located inside in the radial direction Z with respect to the outer edge 42a and outside in the radial direction Z with respect to the cylindrical body 41.SELECTED DRAWING: Figure 4B
