  • Wiper device for cleaning roof-light window, cab, and construction machine
    Patent number: 8806699
    Abstract: A roof-light window wiper device includes a wiper motor having an output shaft; a wiper link coupled to the output shaft, and having an extension extending in a direction crossing the output shaft of the wiper motor, and a drive shaft extending in a direction crossing the extension, and a wiper connected to the drive shaft. The drive shaft and the output shaft extend at the side of the wiper motor relative to the wiper link. The wiper is connected to the drive shaft at the side of the wiper motor relative to the wiper link. Thus, there can be provided a roof-light window wiper device that can have the pressure of the wiper against the surface of a roof-light window increased by decreasing the depression angle of the wiper, and a cab and a construction machine including the roof-light window wiper device.
