    Abstract: A vehicle wiper device includes: a wiper motor; a control unit that drives the wiper motor to be reciprocally rotated and controls a rotation speed of the wiper motor; and a wiper reciprocally rotating to wipe a wiped surface of a vehicle with a blade rubber, in which a tilt direction of a lip part of the blade rubber changes when a rotation direction is reversed. The control unit accelerates a rotation speed of the wiper motor, in a first acceleration section, from 0 to a first speed which is a low speed at a first average acceleration, and to rapidly accelerate the rotation speed of the motor, in a first half of a second acceleration section, to reach a speed which is higher than the first speed and ½ times of a second speed at an average acceleration which is twice or more of the first average acceleration.
