  • Patent number: 8561773
    Abstract: A drive device is provided with a housing 11 and an electromagnetic clutch mechanism 14 accommodated in the housing. The electromagnetic clutch mechanism 14 is provided with an armature 41 rotatably supported in the housing 11, a rotor 42 arranged to face the armature 41 and rotatably supported in the housing 11, and a coil 46. An annular magnet 44 is fixed on the outer circumference surface of the rotor 42. A sensor 15 arranged inside the housing 11 detects a polarity change of the magnet 44 in association with rotation of the rotor 42. The magnet 44 is provided with an annular wall portion 44b extending toward the armature 41 beyond a surface on which the armature 41 is in contact with the rotor 42 with respect to the axial direction. The annular wall portion 44b is spaced radially outward from the armature 41. The annular wall portion 44b prevents abrasion powder produced on actuation of the electromagnetic clutch mechanism 14 from being scattered.

  • Publication number: 20120198770
    Abstract: When a worm wheel rotates relative to an object pinching detection plate due to pinching of a foreign object, protruding pieces respectively formed on opposed surfaces of the worm wheel and the object pinching detection plate engage with each other. Through the engagement, the object pinching detection plate axially moves. At this time, the object pinching detection plate axially moves without rotation, and hence the object pinching detection plate is brought into contact with a movable piece of an object pinching detection switch without rotation. Therefore, wear due to rotation does not occur when the object pinching detection plate and the object pinching detection switch are brought into contact with each other. Thus, deterioration in object pinching detection accuracy due to the wear is prevented.

  • Publication number: 20120192491
    Abstract: A position detection unit includes a rotational member rotatable by a rotational drive force of an output shaft, an operation lever configured to avoid engaging with the rotational member when an open/close position of a window glass is situated out of an insensitive area, and engage with the rotational member when the open/close position of the window glass is situated within the insensitive area, the operation lever being rotated by the rotational drive force of the output shaft transmitted via the rotational member when the operation lever engages with the rotational member, and an insensitive area detection switch for performing a switching operation based on a rotational operation of the operation lever. It is detected whether or not an open/close position of the window glass is situated within the insensitive area based on the rotational operation of the operation lever, and accordingly detection accuracy is enhanced.

  • Patent number: 7934737
    Abstract: A step device for a vehicle including a movable step arranged in a doorway opened and closed by a door is disclosed. The step device includes a drive unit, an open/close mechanism, a projection/retraction mechanism, and a plate cam. The open/close mechanism opens or closes the slide door. The projection/retraction mechanism moves a movable step. The plate cam is rotated by the open/close mechanism and engaged with a bushing arranged on the projection/retraction mechanism to enable or disable power transmission between the open/close mechanism and the projection/retraction mechanism. The plate cam includes a first recess and a second recess. The first recess pushes the bushing during rotation of the plate cam when the slide door is in a range of a predetermined open/close position to enable or disable power transmission between the open/close mechanism and the projection/retraction mechanism.
