PROBLEM TO BE SOLVED: To efficiently transmit the rotating force of a rotary shaft to a worm shaft.SOLUTION: In a motor 10 with a reduction gear, a ball bearing 122 is fixed to a worm shaft 62, and a load transmission member 124 fixed to a gear housing 52 is adjacent to the other side in a first direction with respect to the ball bearing 122 and disposed in contact with the ball bearing 122. Due to this, when thrust load to the other side in the first direction is applied to the worm shaft 62, thrust load is transmitted to the gear housing 52 via the ball bearing 122 and load transmission member 124. By virtue of this, thrust load is restricted from being input to the rotation shaft 32 of a motor body 12. Accordingly, since the rotary shaft 32 and worm shaft 62 arranged on the same axis are restricted from being displaced such that they are bent into an approximately V-shape having a coupling device 90 as its initial point, rotating force of the rotary shaft 32 can efficiently be transmitted to the worm shaft 62.SELECTED DRAWING: Figure 1 |
