Shock absorber loaded in inner cavity of tire enclosed by tire for two-wheeler and rim
First Claim
1. A shock absorber for a two-wheeler which is loaded in the inner cavity of a tire enclosed by a tire for a two-wheeler and a rim, contacts substantially with the entire inner surface of a tire and is compressed at the same time, is circular in the tire circumferential direction and has closed cells;
- said shock absorber for a two-wheeler comprising an expanded rubber containing at least 5 parts by weight of an organic polymer having a softening point of above 40°
C., based on 100 parts by weight of a rubber and 0.1 to 10 parts by weight of a proton acid and/or a phenol derivative based on 100 parts by weight of said rubber.

Abstract
The present invention provides a shock absorber loaded in the inner cavity of a tire enclosed by a tire for a two-wheeler and a rim, which exhibits suitable hardness when starting running and is excellent in cushioning property, both when starting running and during running, due to decrease in hardness as the temperature increases while running. Specifically, the present invention relates to a shock absorber which is loaded in the inner cavity of a tire enclosed by a tire for a two-wheeler and a rim and contacts substantially with the entire inner surface of a tire to be compressed, is circular in the tire circumferential direction and has closed cells; the shock absorber comprising an expanded rubber composition containing at least 5 parts by weight of an organic polymer having a softening point of at least 40° C., based on 100 parts by weight of a rubber component.
