A power window device in which a drive pulley around which a wire to open and close a window is wound is disposed within a case of a power window drive section and a wire guide for guiding the wire is mounted on the case. The wire guide is composed of a first wire guide for guiding one end of the wire and a second wire guide for guiding the other end of the wire. The second wire guide is removably coupled to the first wire guide. A wire guide angle theta 0 between the wire guides can be changed merely by exchanging the second wire guide. Even when a different wire guide angle is required, the size of the component to be replaced can be reduced, as can the cost to manufacture.
