Abstract
A motor bracket to which a wiper motor is fixed, and a DR side pivot holder are coupled together by means of a DR side pipe frame inclined to a plane perpendicular in the axial direction of an output shaft of a wiper motor, and the motor bracket and an AS side pivot holder are coupled together by means of an AS side pipe frame inclined to the plane perpendicular in the axial direction of the output shaft. An output arm is fixed to the output shaft of the wiper motor, and the output arm is disposed between the DR side pipe frame and the AS side pipe frame, and between the connecting rod for coupling a DR side lever and an AS side lever, and the motor bracket.
Claims2
A wiper apparatus for vehicle having a first pivot shaft mounting a first wiper arm, and a second pivot shaft mounting a second wiper arm, the apparatus comprising:
- a first pivot holder for supporting the first pivot shaft oscillatably, the first pivot holder having a first mounting leg which is fixed to a car body panel;
- a second pivot holder for supporting the second pivot shaft oscillatably, the second pivot holder having a second mounting leg which is fixed to the car body panel;
- an elongated motor bracket defining opposite ends disposed between the first pivot holder and the second pivot holder, the motor bracket having one end provided with an insertion pin that is inserted into a support hole of the car body panel to fix the motor bracket to the car body panel such that the motor bracket is inclined with respect to an axis of the support hole toward the first pivot holder;
- a wiper motor having an output shaft mounting an output arm, being fixed to the motor bracket;
- a drive rod for coupling a first lever fixed on the first pivot shaft and the output arm;
- a connecting rod for coupling the first lever and a second lever fixed on the second pivot shaft;
- a first frame, formed separately from the motor bracket and the first pivot holder, disposed at an inclination to a plane perpendicular in the axial direction of the output shaft, having one end fixed to the other end of the motor bracket, and having the other end fixed to the first pivot holder;
- and
- a second frame, formed separately from the motor bracket and the second pivot holder, disposed at an inclination to a plane perpendicular in the axial direction of the output shaft, having one end fixed to an intermediate portion of the motor bracket, and having the other end fixed to the second pivot holder,
- wherein the output arm is disposed between the first frame and the second frame, and between the motor bracket and the connecting rod, at least one of the first pivot shaft and the second pivot shaft is inclined to the output shaft, and the connecting rod is bent in a V-form, and a nearly intermediate portion of the connecting rod is bent away from the motor bracket.
