Abstract
A roller of a track-type traveling vehicle which can increase the life of a bearing supporting a roller shell is provided. The roller includes: a shaft having a cylindrical outer circumferential surface; a roller shell arranged to surround a portion of the outer circumferential surface of the shaft in a circumferential direction, and having a cylindrical inner circumferential surface which faces the outer circumferential surface, and an annular end surface; a collar fixed to the shaft and having an annular facing surface which faces the end surface; a radial sliding bearing arranged between the outer circumferential surface and the inner circumferential surface; and a thrust sliding bearing arranged between the end surface and the facing surface and provided separately from the radial sliding bearing. The roller is provided with an anti-rotation structure which prevents relative rotation of the thrust sliding bearing with respect to the roller shell.
