Abstract: The motor with deceleration mechanism includes: a motor shaft (11), which is accommodated in a motor case (21) and in which an axial end portion (11a) is formed into a spherical shape; a worm, arranged on the motor shaft (11); a worm wheel, accommodated in a gear frame and engaging with the worm; a radial bearing (41), rotatably supporting the motor shaft (11); and a first thrust bearing (42), which is disposed inside the motor case (21), and in which a shaft facing surface (42s) facing the axial end portion (11a) of the motor shaft (11) and a counter shaft facing surface (42c) on the opposite side are respectively formed spherically; an average sliding radius between the first thrust bearing (42) and the motor case (21) is larger than an average sliding radius between the first thrust bearing (42) and the motor shaft (11).

Abstract: A replay plate 44 is set to have a vertically and horizontally symmetrical shape when a worm wheel 33 is viewed from its axial direction; the worm wheel 33 is provided with an accommodating concave portion 33g in which the relay plate 44 is housed so as to be recessed in the axial direction; and a part of a non-slidably contacting surface in a slidably contacting surface 44a of the relay plate 44, i.e., a non-slidably contacting surface S is covered with first and second fixing parts 35a, 35b that are provided around the accommodating concave portion 33g and protrude in a direction intersecting with an axial direction of the worm wheel 33, the non-slidably contacting surface being a surface with which the contact plate is not slidably contacted.
