Claims

[Claims for Utility Model Registration] 1. A play that is attached to two members having inclined chamfered portions having the same angle and in contact with groove surfaces formed in a tapered shape so as to prevent both members from playing in the longitudinal direction. What is claimed is: 1. A rigid elastic ring for preventing backlash, characterized in that an appropriate length of the inner diameter portion of the ring up to the end face serving as the abutment is chamfered. 2. In a rigid elastic ring for preventing backlash, which is attached to a groove surface formed in a tapered shape with two members having inclined chamfered portions having the same angle, in contact with each other so as to prevent backlash in the longitudinal direction of both members. A rigid elastic ring for preventing backlash, characterized in that among the end faces of the abutment part of the ring, at least the boundary between the inner diameter part and the end face is rounded. 3. In a rattling prevention rigid elastic ring that is attached to a groove surface formed in a tapered shape by facing two members having inclined chamfered portions having the same angle, in contact with each other so as to prevent rattling in the longitudinal direction of both members. A rigid elastic ring for preventing backlash, characterized in that a chamfer in the thickness direction is provided in addition to the upper and lower chamfers on the opposing end faces of the abutment part of the ring. 4. In a rattling prevention rigid elastic ring that is attached to a groove surface formed in a tapered shape by facing two members having inclined chamfered portions having the same angle, in contact with each other so as to prevent rattling in the longitudinal direction of both members. A rigid elastic ring for preventing backlash, characterized in that the abutment parts of the rings are widened in the tangential direction. 5. The rattling-preventing rigid elastic ring according to claim 4, wherein the top portion of the end face of the abutment portion of the ring is cut horizontally.
