摘要： A reduction-transmission mechanism includes: an input member formed of an external gear that makes circular motion with an eccentric amount; a rotation force applying member formed of an internal gear that is in mesh with the input member; and output members that receive and output rotation force applied to the input member by the rotation force applying member, and that are passed through the respective pin insertion holes. Each of the output members is provided with a needle roller bearing at a portion that is able to contact an inner periphery, which defines a corresponding one of the through-holes, and the input member has third oil supply passages that extend from the center hole to the pin insertion holes, and lubricating oil is supplied to the needle roller bearings through the third oil supply passages by centrifugal force generated in accordance with rotation of the motor shaft.
