Abstract
A roller device includes a roller main body, a shaft member, flanges, a position restricting member, a plate-shaped member, a biasing member, and a securing member. The shaft member is inserted into the roller main body and the flanges in contact with both ends of the roller main body. The position restricting member is secured to the shaft member at an end portion side of the shaft member with respect to the flange. The position restricting member restricts an axial position of the flange. Movement of the plate-shaped member toward the end portion side in an axial direction is restricted by the position restricting member. The biasing member biases the flange toward a center side in the axial direction. The securing member is disposed at the end portion side of the shaft member with respect to the plate-shaped member. The securing member engages the position restricting member.
