PROBLEM TO BE SOLVED: To provide a worm reducer which enables improvement of assemblability and inhibits increase of the number of components.SOLUTION: A worm reducer 15 includes a biasing member 60 which biases a second end part 18b of a worm shaft 18 in a direction such that the second end part 18b approaches a worm wheel 19. A guide member 50 for guiding movement of the second end part 18b is held in a holding hole 44 of a housing 17. The holding hole 44 has an opening 44a at one end 171 of the housing 17. The guide member 50 includes: a ring part 51 which is fitted in the holding hole 44 and guides movement of the second end part 18b; and a closing part 52 which closes one end 511 of the ring part 51 and closes an opening 44a of the holding hole 44.SELECTED DRAWING: Figure 2 |
