Roller device and roller shell for track-type work vehicle
Roller shell has a first cylindrical part and a second cylindrical part. An outer diameter of the first cylindrical part is larger than an outer diameter of the second cylindrical part, and an inner diameter of the first cylindrical part is smaller than an inner diameter of the second cylindrical part. The first cylindrical part fits to a small-diameter bushing part, and the second cylindrical part fits to a large-diameter bushing part. The second cylindrical part has a slit which extends through an outer circumferential surface and an inner circumferential surface and is open at an end surface. The roller shell engages with a step part. An engaging member fits to a groove and engages with the slit. A retainer is formed to have an annular shape and is detachably attached to bushing to hold an end surface of the roller shell.
