A motor may include an urging member which is mounted on a fixed body for urging the bearing, and a pair of engaging grooves formed on the fixed body. The urging member may includes a pair of hook parts which are bent from respective tip ends of a pair of side plate parts. When the urging member is mounted on the fixed body, a pair of the hook parts are inserted from open ends and engaged with a pair of the engaging grooves and, when an outward force is applied to the urging member, the hook parts abut with an opposite inner wall of the engaging grooves located on a tip end side in the axial line direction of the motor to prevent the hook parts from being disengaged from the engaging grooves.
