MOTOR WITH DECELERATION MECHANISM
A worm wheel housing portion 19 of a gear case 16 has a bottomed cylindrical shape having a bottom wall portion 19a and a cylindrical wall portion 19b, and a bottom cover 35 is assembled at an opening portion of the worm wheel housing portion 19 so as to seal the opening portion. Among a plurality of latching structures for assembling them, as a latching structure other than those on a worm housing portion 17 side, a groove 44 is formed to a latching claw 38b extending along the cylindrical wall portion 19b from an outer circumferential portion of the bottom cover 35, and a projecting piece 47 engaged with the groove 44 is provided on an outer wall surface of the cylindrical wall portion 19. Wall portions 53 and 54 covering side surfaces a and tip face of the latching claw 38b are provided on the outer wall surface of the cylindrical wall portion 19b, so that breakage of the latching claw 38b or release of the engagement of the latching claw 38 to be caused, for example, when an object hits the latching claw 38b can be prevented.
