Abstract

A wiper of a vehicle wiper device moves between a first position, which is a stop position, and a second position. A first pivot member is pivoted back and forth about a first axis by a drive force of a drive source. A second pivot member is pivotal about a second axis. A coupling pivot member is coupled to the first pivot member pivotally about a third axis and the second pivot member pivotally about a fourth axis. The wiper is coupled to and pivoted integrally with the coupling pivot member. A third position is located between the first position and the second position. A line extending through the third axis and the fourth axis is parallel to a line extending through the first axis and the second axis when the wiper is in a first movable range between the first position and the third position.

Dependent claims

A vehicle wiper device comprising:

a wiper that moves between a first position, which is a stop position, and a second position, which is an upper reversing position, to wipe a wiping surface;
a drive source;
a first pivot member pivoted back and forth about a first axis, which is an axis of an output shaft of the drive source, by a drive force of the drive source to move the wiper, wherein the first axis is arranged at a fixed position relative to a vehicle body;
a second pivot member pivotal about a second axis, wherein the second axis is arranged at a position differing from the first axis that is a fixed position relative to the vehicle body;
and
a coupling pivot member coupled to the first pivot member pivotally about a third axis and coupled to the second pivot member pivotally about a fourth axis, wherein the wiper is coupled to the coupling pivot member to pivot integrally with the coupling pivot member and to extend from the coupling pivot member toward an opposite side of the first pivot member and the second pivot member, wherein
a third position is located between the first position and the second position in a direction in which the wiper moves from the first position toward the second position, and a first movable range is formed between the first position and the third position,
a second movable range is formed between the third position and the second position,
the first movable range is smaller than the second movable range,
a line extending through the third axis and the fourth axis is parallel to a line extending through the first axis and the second axis when the wiper is in a predetermined position of the first movable range,
the line extending through the third axis and the fourth axis intersects with the first axis when the wiper is in a predetermined position of the second movable range,
the wiper is one of two wipers,
the two wipers respectively include basal ends located at two ends in a vehicle widthwise direction,
the two wipers swing back and forth in opposite directions to perform opposing wiping,
the drive source is one of two drive sources, and
the two drive sources are respectively arranged in the two wipers.
