Claims

[Scope of utility model registration request]

A roller and a driven wheel are fitted around the roller shaft so as to be relatively rotatable, and cut surfaces are formed at both ends of the roller shaft, the phases of which are mutually displaced in the circumferential direction.
Brackets with roller shaft locking grooves are provided on the inner surfaces of the pair of left and right support frames, and
A driving body with which the passive wheel body interlocks is disposed on one support frame, and the locking groove of one bracket is formed so that the lowermost receiving part is slightly wider than the diameter of the roller shaft, and the lowermost part of the locking groove is formed to have a width slightly wider than the diameter of the roller shaft. A roller conveyor characterized in that an inward protrusion is provided, and a locking groove of the other bracket is formed to have a width narrower than a roller shaft diameter.
