Abstract: A housing includes a support surface that supports an axial force of a worm wheel. Ribs are arranged radially inward of a peripheral wall of one end of the housing and at least partially overlaps with the worm wheel in the axial direction of the rotatable member. Ribs contact a bracket and support the support surface of the gear housing relative to the bracket in the axial direction of the worm wheel when the axial force of the worm wheel is applied to the ribs.

Abstract: A housing is held by a bracket of a vehicle seat and receives a worm wheel and a threaded shaft. The shaft is driven linearly through the worm wheel. One end of the housing contacts the bracket and includes a receiving recess, which is recessed in the axial direction of the worm wheel. A sensor unit is installed in the recess of the one end of the housing and includes a support wall, which supports the housing relative to the bracket in the axial direction of the worm wheel.

Abstract: An assembled part for being placed on a conveyor frame having a pair of guides along a direction of conveyance, being located between an upstream delivery member and a downstream positioning member and being conveyed and guided through the movement of them as one body, which includes a main body, a pair of guided portions facing the guides, a delivered portion facing the delivery member, a positioned portion facing the positioning member.

Abstract: In an electric motor having a rotation detection sensor, a pair of engagement recesses are provided on an axial end surface of a resin cylindrical body of a commutator. A permanent magnet is held around a rotary shaft of the motor with its one axial end surface being in abutment with the axial end surface of the cylindrical body. A pair of engagement recesses is provided on the other axial end surface of the magnet. A resin busing having a cylindrical part and a disk part is fitted on the rotary shaft at the side of the other axial end surface of the magnet. A pair of engagement protrusions is formed on the cylindrical part to be engaged with the engagement recesses of the cylindrical body, thereby restricting a relative movement between the bushing and the cylindrical body. Further, a pair of engagement protrusions is formed on the disk part to be engaged with the engagement recesses of the magnet, thereby restricting a relative movement between the bushing and the magnet.
