To provide a roller 1 capable of improving comfortableness in riding while providing a striking noise reducing function, allowing parts to be manufactured with relatively low precision, increased productivity and a reduced cost.

The roller comprises a roller part 7 formed with a circular installation groove in a rotation surface 7a, and a shock absorbing ring 8 engaged upon installation with the installation groove of the roller part 7. The shock absorbing ring 8 comprises a part to be compressed by receiving load when rotated (compressed part) 8a that is contained in the installation groove of the roller part 7. At the part 8a, the rotary surface 7a of the roller part 7 gets in contact with a counter member 9.
