Abstract
A tolerance ring that has a ring shape approximately circling along a predetermined direction includes a plurality of projections, wherein the curvature radiuses of end portions in a circling direction are smaller than the curvature radius of a portion other than the end portions in the circling direction.
Claims7
A tolerance ring comprising:
- a ring shape approximately circling along a predetermined direction;
- and
- a plurality of projections, wherein
- curvature radiuses of end portions in a circling direction are smaller than a curvature radius of a portion other than the end portions in the circling direction,
- the curvature radiuses of end portions are adapted to be equal to a curvature radius of a coupling section connecting different parts,
- a curvature radius of the portion other than the end portions in the circling direction is larger than the curvature radius of the coupling section, and
- the tolerance ring is adapted to be inserted into the coupling section and adapted to deform when inserted into the coupling section.

A combination of a tolerance ring and a coupling section, comprising:
- the tolerance ring being inserted into the coupling section connecting different parts, the tolerance ring comprising:
- a ring shape approximately circling along a predetermined direction;
- and
- a plurality of projections, wherein
- curvature radiuses of end portions in a circling direction are smaller than a curvature radius of a portion other than the end portions in the circling direction,
- the curvature radiuses of end portions are substantially equal to a curvature radius of the coupling section, and
- a curvature radius of the portion other than the end portions in the circling direction is larger than the curvature radius of the coupling section, and
- the tolerance ring deforms when inserted into the coupling section.
