Abstract: A control circuit board is received in a circuit board receiving case without being directly joined to the circuit board receiving case and has a circuit board side connector. The circuit board side connector is installed to a main body side connector of a gear housing in an installation direction parallel to a rotatable shaft of the motor main body to supply electric power to the motor main body through the main body side connector. A pin main body of a fixing pin is received into a fixing through hole of the control circuit board through a pin receiving through hole of the gear housing in a direction perpendicular to the installation direction of the circuit board side connector.

Abstract: An electronic control unit is received in an electronic control unit receiving portion of a gear housing of a motor, and a support plate is press fitted into a couple of plate receiving holes, which penetrate through opposite walls, respectively, of the gear housing in a direction perpendicular to an axial direction of the motor at an open end of the gear housing. A yoke housing of a motor unit is secured to the support plate with screws while a brush holder is clamped between a flange of the yoke housing and the support plate.

Abstract: A door closer includes a latch that engages with a striker and first and second ratchets that engage with the latch. When the latch receives the striker and rotates from an initial position to a fully latched position, the door is moved to a fully closed position. When the ratchets disengage from the latch, the latch returns from the fully latched position to the initial position. The striker thus disengages from the latch, and the door moves from the fully closed position to a released position. After the ratchets disengage from the latch, each ratchet is held at a position at which the ratchet cannot engage with the latch unless the door is located at a predetermined position separate from the released position in a door opening direction.

Abstract: A door closing system for locking and unlocking a door using a single actuator has a motor, a latch to be engaged with a door striker and a driving cam for driving the latch. An output shaft of the motor is disposed in parallel with a shaft which rotatably holds the latch and the driving cam, thereby reducing an installment space of the latch and the driving cam. Further, the actuator has plural reduction gears rotated by the motor, and a pattern is disposed on a surface of one of the reduction gears. First to third contacts are disposed to slide on the pattern, thereby producing detection signals of a rotation position of the reduction gear. An operation state of the door closing system is detected according to the detected rotation position of the reduction gear. Thus, the door closing system can be controlled accurately with a single detection sensor.
