Wiper device

A wiper device, wiping a wiping surface through a swing movement of a swing shaft, the wiper device comprising:

• a wiper arm, wherein a proximal end side is fixed to the swing shaft, and a blade installation part is provided on a distal end side;
• a wiper blade, having a blade rubber sliding on and contacting the wiping surface, and installed to the blade installation part;
• and
• an inclination mechanism, provided at the wiper arm or the wiper blade, and at least inclining the wiper blade with respect to the wiping surface so that a center of the blade installation part is disposed forward in a wiping direction with respect to a center of the blade rubber,
• wherein the inclination mechanism is provided at the wiper blade,
• the inclination mechanism comprises:
• a clip member, installed to the blade installation part;
• and
• a support member, having a linking pin rotatably linked to the clip member, and supporting the blade rubber, and
• the linking pin is inclinable in the wiping direction with respect to the clip member,
• wherein the clip member comprises:
• a first abutting part extending in a longitudinal direction of the wiper blade;
• and
• a pair of sidewall parts integrally provided with the clip member,
• the support member has a second abutting part extending in the longitudinal direction of the wiper blade and abutted against by the first abutting part,
• the first abutting part is connected with a first inclination surface and a second inclination surface provided on outer sides of the pair of sidewall parts,
• the first inclination surface is provided on a side of the wiping surface of the clip member, and
• the second inclination surface is disposed on a side opposite to the wiping surface of the clip member,
• wherein the clip member has an engagement concave part engaged with the linking pin,
• the engagement concave part has a groove part formed in a U shape,
• the groove part includes an opening part guiding engagement of the linking pin to the engagement concave part,
• a pin support part supporting a longitudinal direction central part of the linking pin is provided at a longitudinal direction central part of the engagement concave part, and
• on two sides of the pin support part in a longitudinal direction of the engagement concave part, taper parts whose gaps with the linking pin gradually increase as a distance from the pin support part increases are formed.
