Abstract
In a worm reduction gear, a second bearing that supports a second end of a worm shaft and a guide member are housed in a holding hole in a housing. A bias member biases the second end of the worm shaft toward the worm wheel (in a second direction). The guide member is elastically fitted in the holding hole in the housing to guide movement of the second end via the second bearing. A slit is fanned in the guide member. Stress is relieved which is exerted on the guide member when the guide member is elastically fitted in the holding hole.
