Abstract: The present invention relates to a door module capable of raising and lowering a window glass with few components in number. The door module has a window motor, a power transmission arm, a guide rail, and a carrier. The power transmission arm is operably coupled to the window motor. The carrier is supported by the guide rail so as to be movable along the longitudinal direction of the guide rail. The carrier has a receiving rail engaged with an engaging projection of the power transmission arm so that the carrier is moved along the longitudinal direction of the guide rail in accordance with the rotation of the power transmission arm. The carrier also has protrusions engaged with the guide rail so as to restrain the carrier from moving relative to the guide rail along a direction that intersects the longitudinal direction of the guide rail.

Abstract: A terminal for supplying power to a motor portion is inserted in a housing formed by molding resin, and both ends of the terminal are exposed from the housing. When the housing is molded, an insulation member such as first and second plates contacts a die for forming the housing, and the terminal is engaged with the insulation member before the housing is molded, so that an attachment position of the terminal is set relative to the die through the insulation member. The insulation member is inserted in the housing together with the terminal by pouring melted resin in the die. Thus, the housing in which the terminal is inserted can be readily molded, and it can prevent liquid from being introduced to the terminal in the housing.

Abstract: A bearing device for use with of a motor, includes a worm-like thread, which is threaded to a rotor shaft, and which engages a worm wheel. The rotor shaft is supported by a pair of radial bearings. When the rotor shaft is not caused to bend, a third radial bearing is spaced away from the outer peripheral surface of the rotor shaft. When the rotor shaft is caused to bend under the counter force generated by the worm wheel, the rotor shaft is supported by the third radial bearing along the bend direction.

Abstract: An electric rotating machine has a wire connector to external wires. The wire connector has a connection box formed in the housing of the electric rotating machine and including an opening used to pour a filler into the connection box; a plurality of terminal fittings each connected at one end to the internal circuit of the electric rotating machine, the other end of each of the terminal fittings extending into the connection box through the wall thereof and being connected to the respective one of the external wires; and a waterproofing and insulating filler poured into and solidified in the connection box through the opening, each of the terminal fittings having wider side faces parallel to the direction of flow of the poured filler.
