  • Publication number: 20170254135
    Abstract: A vehicle door glass lifting device includes a lifting and lowering mechanism by which a door glass is lifted or lowered relative to a window frame of a vehicle door, a contact sensor that is arranged on a top end surface of the door glass and extended along a longitudinal direction of the top end surface of the door glass, and a control part that controls the lifting and lowering mechanism. The contact sensor can detect a contact state including a contact length with a contact object. The control part determines whether or not the contact object is a foreign object based on the contact state detected by the contact sensor, and the control part lowers the door glass when the contact object is determined as the foreign object.
