Abstract
A motorized conveyor roller prevents slip between a power transmission mechanism in a roller tube and the roller tube due to aging. The power transmission mechanism includes a first closed-bottom cylindrical member fit over a second closed-bottom cylindrical member and a bolt for axially pressing the members against one another. The first member receives torque from a motor and a double-sided tape is laid on an outer surface of the first member. Facing surfaces of the first and second members are tapered, and the circumferential wall with the double-sided tape is expandable diametrically. The bolt diametrically expands the circumferential wall pressed by the tapered surface. Thus, an adhesive force of the double-sided tape sandwiched between the circumferential wall and the roller tube is exerted to adhere the outer surface of the first member to an inner surface of a roller tube.
