Abstract
A vehicle wiper device includes a first driving lever, a second driving lever, a first driven lever, a second driven lever, a first wiper arm, a first wiper blade, a second wiper arm, and a second wiper blade. The first driving lever is pivoted by a driving force of a first drive source. The second driving lever is pivoted by a driving force of a second drive source. A pivoting speed of the second wiper blade from a lower reversal position is set to be greater than a pivoting speed of the first wiper blade from a lower reversal position.
Claims6
A vehicle wiper device, comprising:
- a first driving lever having a proximal end that is pivotal about a first axis located at a fixed position in relation to a vehicle body, the first driving lever being pivoted by a driving force of a first drive source;
- a second driving lever having a proximal end that is pivotal about a second axis located at a fixed position in relation to the vehicle body, the second driving lever being pivoted by a driving force of a second drive source;
- a first driven lever having a proximal end connected to the first driving lever and pivotal about a third axis, the third axis being located at a distal side of the first driving lever;
- a second driven lever having a proximal end and a distal end, the proximal end being connected to the first driven lever and pivotal about a fourth axis, the fourth axis being located at a distal side of the first driven lever, the distal end being connected to the second driving lever and pivotal about a fifth axis, and the fifth axis being located at a distal side of the second driving lever;
- a first wiper arm provided so as to operate integrally with the second driven lever;
- a first wiper blade connected to a distal end of the first wiper arm and reciprocally wiping a wiped surface between upper and lower reversal positions;
- a second wiper arm;
- and
- a second wiper blade connected to a distal end of the second wiper arm and reciprocally wiping the wiped surface between upper and lower reversal positions,
- wherein a pivoting speed of the second wiper blade from the lower reversal position is set to be greater than a pivoting speed of the first wiper blade from the lower reversal position.
