Abstract:
1. An output power transmission device that transmits rotation of a rotary shaft having a worm section on an outer periphery thereof to an output shaft through a wheel gear meshing with the worm section, the output power transmission device comprising: a transmission member made of metal and attached to the wheel gear in an axial direction of the wheel gear such that the transmission member directly engages with the wheel gear in a rotation direction and in the axial direction for transmitting rotation of the wheel gear to the output shaft, the transmission member being attached to the output shaft to be rotatable integrally with the output shaft; a restriction section provided at a position where the restriction section sandwiches the transmission member with the wheel gear in the axial direction for restricting movement of the transmission member in a direction opposite from the wheel gear side; and a pressing member provided in one of the wheel gear and the transmission member to press the transmission member by an elastic force of the pressing member against either one of the wheel gear and the restriction section in the axial direction, the pressing member having an elastic claw section that is formed in the one of the wheel gear and the transmission member and that presses another one of the wheel gear and the transmission member in the axial direction, wherein the transmission member has a structure pressing against the restriction section in the axial direction by an elastic force of the elastic claw section.
