Abstract
A shock absorbing member includes a first elastic body and a second elastic body at least partially overlapping the first elastic body in a rotational direction of a first member and the second member. An elasticity of the first elastic body is different from an elasticity of the second elastic body.
Claims24
In a shock absorber for mounting between a first frame member and a second frame member of a bicycle, wherein the shock absorber includes a first member adapted to couple to the first frame member, a second member adapted to couple to the second frame member, and a coupling mechanism coupling the first member with the second member so that the first member rotates relative to the second member around a rotational axis or an axle, a shock absorbing member for placement between the first member and the second member so that the shock absorbing member expands and contracts in response to relative rotation of the first member and the second member, wherein the shock absorbing member comprises:
- a first elastic body adapted to be positioned between a first protrusion on said first member and a second protrusion on said second member;
- a second elastic body at least partially overlapping the first elastic body when viewed in a rotational direction of the first member and the second member and adapted to be positioned adjacent to said first elastic body between said first elastic body and said first protrusion;
- and
- wherein an elasticity of the first elastic body is different from an elasticity of the second elastic body.

- a first elastic body adapted to be positioned between a first protrusion on said first member and a second protrusion on said second member;
- a second elastic body at least partially overlapping the first elastic body when viewed in a rotational direction of the first member and the second member and substantially perpendicular to a rotational axis of an axle, said second elastic body adapted to be positioned adjacent to said first elastic body lined up with said first elastic body;
- and
- wherein an elasticity of the first elastic body is different from an elasticity of the second elastic body.
