Patent ID: 8826592

Claim:
A window regulator device, comprising: a power source; an output shaft connected to the power source and rotatable by a force generated by the power source; a drive force transmission mechanism for transmitting the force to a window glass of a vehicle so as to open and close the window glass; and an object pinching detection unit for detecting whether or not a foreign object is pinched between the window glass and a window frame, a position detection unit for detecting a position of the window glass relative to the window frame, wherein the object pinching detection unit comprises: an input-side rotational member rotatable by the force of the power source; an output-side rotational member coupled to the output shaft so that the output-side rotational member is integrally rotatable with the output shaft and axially movable relative to the output shaft, the output-side rotational member arranged coaxially with the input-side rotational member so as to face the input-side rotational member; an elastic member interposed between the input-side rotational member and the output-side rotational member so as to transmit a rotational drive force of the input-side rotational member to the output-side rotational member when the input-side rotational member rotates in one rotational direction; a cam formed respectively on opposed surfaces of the input-side rotational member and the output-side rotational member so that, when the input-side rotational member rotates in the one rotational direction relative to the output-side rotational member, the output-side rotational member is axially moved by said cams; and an object pinching detection switch for performing a switching operation based on the axial movement of the output-side rotational member, and wherein the position detection unit comprises: an insensitive area detection switch which detects whether or not the position of the window glass is in an insensitive area which is immediately before the window glass is closed; a reverse operation area detection switch which detects whether or not the position of the window lass is in a predetermined reverse operation area; and an operation lever which is rotatably supported by the output shaft, and wherein the insensitive area detection switch and the reverse operation area detection switch are switched by the rotation of the operation lever.
