Abstract
A vehicle wiper device moves a wiper back and forth between a bottom reversing position and a top reversing position. A drive source rotates an output shaft back and forth about a first axis within a rotational angle range of less than 360°. A link mechanism includes a wiper joint coupled to the wiper. The link mechanism rotates the wiper joint back and forth around a second axis within a rotational angle range that is smaller than the rotational angle range of the output shaft. The link mechanism is configured so that torque of the wiper joint is greater when the wiper is at the bottom reversing position than when the wiper is at the top reversing position.
