A wiper apparatus is provided with: a wiper arm () which is swung about a rotation shaft (); and a wiper motor () for generating drive power to be transmitted to the rotation shaft (), the wiper apparatus is provided with a power transmission mechanism () for transmitting the drive power from the rotation shaft () to the wiper arm (), the power transmission mechanism () is provided with: a link member () fixed to the rotation shaft (); and a support shaft () fixed at a position on the link member (), which deviates from the rotation shaft (), and configured to support the wiper arm (), a coupling section between the support shaft () and the wiper arm () is positioned in front of the front end of the front glass (), and at least one part of the wiper motor () is located within the projection region of the front glass (), thereby suppressing the increase in the number of parts.

Wiper apparatus

A wiper bladelinked to a wiper armhas a blade rubberand a rubber holderwith a U-shaped section, wherein the rubber holderis formed shorter in axial length than the blade rubberand surrounds an intermediate portion of the blade rubber. Both end portions in a longitudinal direction of the rubber holderare provided with a pair of holding portionsand, wherein the holding portionhas a holding clawengaged with a stopper portionprovided in a holding grooveof the blade rubberand the holding portionhas a holding clawengaged slidably with the holding grooveof the blade rubberand the rubber holderis linked to the blade rubberby two position of these holding portionsand

Wiper blade

A connection member that includes right and left side walls; a shaft support portion that is swingably fitted onto a support shaft that is provided at the blade main body; upper and lower pieces that are formed so as to be continuous from the shaft support portion; and projections that come into sliding contact with inner side surfaces at the opening are formed on outer side surfaces of the right and left side walls, wherein: the shaft support portion and the upper piece are integrally formed so as to bridge the right and left side walls, the lower piece is formed so as to be separated from the right and left side walls by a groove, and outward projection amounts of the projections are larger at the lower piece than at the upper piece.

Connection member in wiper blade

A wiper bladecomprises a rubber holderattached to a tip of a wiper armand a blade rubbersupported by the rubber holder. The rubber holderis formed into a U-shaped cross section, and an intermediate portion of the blade rubberis covered with the rubber holder. Also, both sides of the rubber holderare provided with coversin a longitudinal direction in series. Each of the coverbecomes rotatable to the rubber holderin a direction perpendicular to a front windshield glass, and exposed portions from the rubber holderof the blade rubberare covered with these coversin an elastically deformable state.

Windshield wiper

A wiper apparatus including right and left hand pivot shafts and a wiper motor are incorporated into an integrated modular type holder member. A mounting section having a generally trapezoidal configuration is formed on a pivot holder to extend therefrom outwardly with respect to one of the pivot shafts. The wiper apparatus includes a trapezoidal insertion hole on a vehicle body side. The mounting section is inserted into the insertion hole loosely in a tilted posture when the pivot holder takes a mounting posture, and for mounting the wiper apparatus, using, as a lever, a supporting portion formed on the vehicle body side, the mounting section is pressed against an upper edge of the insertion hole having a smaller dimension.
