Patent ID: 8726573

Claim:
A window regulator device, comprising: a power source; an output shaft connected to the power source and rotatable by a force that is generated by the power source; a drive force transmission mechanism for transmitting a rotational drive force of the output shaft to a window glass of a vehicle so as to open and close the window glass by the rotational drive force of the output shaft; and a position detection unit that detects whether or not an a position of the window glass is situated within a specific positional area, wherein the position detection unit comprises: a rotational member rotatable by the rotational drive force of the output shaft; an operation lever which does not engage with the rotational member when the window glass is situated out of the specific positional area and engages with the rotational member when the window glass is situated within the specific positional 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 a specific positional area detection switch for performing a switching operation based on a position of the operation lever.
