摘要： In a worm reduction gear, a second bearing (34) that supports a second end of a worm shaft (18) and a guide member (50q, 50s, 50t, 50) are housed in a holding hole (44) in a housing (17). A bias member (60) biases the second end of the worm shaft toward the worm wheel (19) 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 (53) is formed 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.

摘要： A pair of wedge-shaped pieces (24, 24) are provided in an annular space (34) that is defined between an inner circumferential surface of a holding recess portion (21) and an outer circumferential surface of a bearing holder (22) in two position that are symmetrical with each other with respect to a meshing portion between a worm wheel (13) and worm teeth (17) and an imaginary plane ± that contains a center axis of a worm (14) in such a way as to fill the annular space (34). Then, an elastic force is imparted to both the wedge-shaped pieces (24, 24) in a direction in which the pair of wedge-shaped pieces move away from the meshing portion in relation to a circumferential direction. According to the above, in a worm reduction gear including a biasing device that elastically biases the worm teeth towards the worm wheel, a distal end portion of the worm is prevented from being displaced in a direction that is at right angles to the biasing direction.

摘要： There is provided a method of assembling a worm reducer, which includes causing a worm wheel to be rotatably supported in a wheel accommodation part, externally fitting a pair of bearings at tip-side and base-side positions of a worm, inserting the worm into a worm accommodation part from an opening side thereof at a state where the worm is offset outward in a radial direction of the worm wheel with respect to a center axis of the worm accommodation part, causing the bearing which is externally fitted to a leading side in an insertion direction of the worm to pass an outer diameter-side of a part of an outer peripheral edge of the worm wheel, which protrudes most into the worm accommodation part, causing the worm teeth to mesh with the worm wheel, and further inserting the worm to a predetermined position in the worm accommodation part.

摘要： A slide member (26) is externally fitted to an outer peripheral surface of an outer ring (20) configuring a tip side bearing (9a) for supporting a tip portion of a worm shaft (6a) so as to be displaceable in an axial direction. A first inclined cylindrical face portion (32) which is an inclined surface disposed on an outer peripheral surface of the slide member (26), and a second inclined cylindrical face portion (30) which is an inclined surface disposed on an inner peripheral surface of a guide member (28) internally fitted and fixed to a holding hole (10a) of a housing (3a) are fitted to each other so as to be slidable in an inclined direction of the respective inclined cylindrical face portions (32, 30). An elastic ring (29) which biases a bearing holding member (26) against to one side in the axial direction is disposed. This realizes a structure which can shorten an axial dimension of a tip side portion of the worm shaft in an electric power steering device including biasing means for minimizing backlash in a meshing portion of a worm reduction gear.
