摘要： An electric power steering device includes a power transmission joint (21) which coaxially couples an output shaft of a steering assist electric motor to an input shaft of a speed reduction mechanism for power transmission. The power transmission joint (21) includes first and second engagement members (41, 42) and an elastic member (43) disposed between the first and second engagement members (41, 42). The elastic member (43) includes an annular main body (44) and a plurality of engagement arms (45) provided at a predetermined interval circumferentially of the main body (44). The engagement arms (45) are engaged with engagement projections (55, 56) of the first and second engagement members (41, 42) circumferentially (X1) of the main body (44). Power transmission faces (46, 460) of the engagement arms (45) include power transmission faces (460) each having a relatively great interference (d1) and power transmission faces (46) each having a relatively small interference (d2).

摘要： An electric power steering device (1) is provided which transmits output rotation of an electric motor for generating a steering assist force (16) to a steering mechanism (64) via a driving gear (22) and a driven gear (21). A housing (8) has a support hole (28) for supporting one end portion (23) of a shaft (20) co-rotatable with the driving gear (22) via a bearing (26) in such a manner as to permit the one end portion (23) to be offset toward the driven gear (21) radially of the driving gear (22). A biasing member (33) which biases the driving gear (22) toward the driven gear (21) includes an arcuate main portion (47) fitted around an outer peripheral surface (58) of an outer ring (36) of the bearing (26) and opposed to an inner peripheral surface (42) of the support hole (28). A pair of movement restriction portions (50, 51) which restrict circumferential movement of the main portion (47) are respectively provided at a pair of arc ends (48, 49) of the main portion (47). A resilient tongue (52) which biases the driving gear (22) toward the driven gear (21) via the bearing (26) is provided only on one of the movement restriction portions (50).

摘要： In an electric power steering system, a second bevel gear is allowed to move toward a first bevel gear and is biased by a biasing member toward the first bevel gear thereby to be moved toward the first bevel gear as following the wearing away of these bevel gears. In an electric power steering system, a support shaft formed with the first bevel gear at its distal end is rotatably supported by a retaining member, which is mounted to a support-shaft housing as allowed to move axially of the support shaft. The retaining member is adjusted for its position relative to the support-shaft housing with respect to the axial direction of the support shaft by means of a retaining member adjuster. The first bevel gear is moved toward the second bevel gear as following the wearing away of these bevel gears. In an electric power steering system, the support shaft formed with the first bevel gear at its distal end is allowed to move toward the second bevel gear and is biased by the biasing member toward the second bevel gear, so that the first bevel gear is moved toward the second bevel gear according to the wearing away of these bevel gears.

摘要： A motor-driven type power steering apparatus includes: a drive gear connected to an output shaft of a motor; a driven gear in mesh with the drive gear, which is connected to a steering unit; a bearing for supporting one end of the drive gear; a support portion in which the bearing is disposed; and a curved leaf spring which has a length larger than a peripheral length of the bearing and fitted between the bearing and the support portion in a resiliently deformed state. The curved leaf spring urges the bearing so that a distance between an axis of the driven gear and an axis of the drive gear decreases.
