速機構付モータの組付け構造。 A large diameter worm gear integrally attached to the tip of the motor shaft protruding from the opening edge of the motor yoke is meshed with a worm wheel housed inside a casing that is integrally attached to the opening edge side of the motor yoke. In a motor with a worm reduction mechanism configured by integrally interposing a motor frame provided with a brush holder for a brush that comes into sliding contact with a commutator between an opening edge of the motor yoke and a casing, the motor shaft is connected to the motor shaft. The bearing is freely rotatably inserted into the motor frame at a position on the casing side and at an intermediate position between the motor yoke opening edge and the worm gear attachment part, while a through hole is formed in the motor frame to allow the worm gear and the bearing to pass through. ,
A bearing holding part is formed at the tip to fit and hold the outer peripheral surface of the bearing so as to restrict movement in the axial direction of the bearing that has passed through the through hole, and a plurality of protruding pieces having elasticity in the radial direction are attached to the worm gear side. The bearing is supported by the casing via the bearing holder by fitting the outer circumferential surface of the bearing holding part into contact with the inner circumferential surface of a support hole formed in the casing. An assembly structure for a motor with a worm reduction mechanism.
