Abstract:
A wiper device for wiping a window supported by a support, the wiper device being located between the window and the support, wherein the window opens and closes an opening in the support, the device comprising:an actuator attached to the support, wherein the actuator has an output shaft and a first coupler member attached to the output shaft, and the actuator pivots the first coupler member in a first angle range; a power transmission unit, the power transmission unit including a shaft holder attached to the window, a pivot shaft supported by the shaft holder and a second coupler member attached to the pivot shaft, wherein, when the window is closed, the second coupler member is coupled to the firs coupler member to transmit rotation of the output shaft to the pivot shaft; a wiper arm attached to the pivot shaft, wherein, when the actuator is activated with the second coupler member coupled to the first coupler member, the wiper arm pivots in an angle range corresponding to the first angle range; and a positioning mechanism, wherein, when the wiper device is installed, the positioning mechanism provisionally fixes the position of the power transmission unit relative to the actuator such that the axis of the pivot shaft is aligned with the axis of the output shaft, wherein the positioning mechanism is located between the first coupler member and the shaft holder to connect the shaft holder to the first coupler member.
