<P>PROBLEM TO BE SOLVED: To provide a motor capable of suppressing noise due to undesired play of a worm shaft. <P>SOLUTION: A joint 16 is provided to a rotary shaft 8 rotatably in one body, and a connection hole 28 into which a connection projection part 15a provided to a worm shaft 15 is inserted while having clearances C1, C2 in a peripheral direction and a radial direction is formed in the joint 16. A peripheral buffer part 31 and a radial buffer part 32 are interposed in the clearance C1 in the peripheral direction and the clearance C2 in the radial direction between the connection hole 28 and connection projection part 15a respectively. The connection hole 28 and connection projection part 15a being configured to abut against each other in the peripheral direction while compressing and deforming the peripheral buffer part 31 in the peripheral direction in a state in which the rotary shaft 8 and joint 16 rotate. <P>COPYRIGHT: (C)2013,JPO&INPIT |
