Wiper for use in a vehicle

A wiper apparatus for use in a vehicle for wiping a windshield glass comprising:

• a holder fixed to a baseplate of a vehicle body;
• an inner bearing rotatably supported in said holder so as to rotate relative to the vehicle body about an axis of said inner bearing;
• a pivot shaft rotatably supported in said inner bearing and inclined relative to said axis, said pivot shaft reciprocatively rotating a wiper arm fixed to said pivot shaft;
• and
• a rotating means comprising a lever crank means coupled to a driving means, for reciprocatively rotating said inner bearing in a direction opposite to the direction of reciprocating rotation of said pivot shaft with said pivot shaft, said lever crank means comprising a first driving apparatus having a pivot shaft driving member for transforming a rocking movement from said driving means into rotational movement for transmission to said pivot shaft, second driving apparatus having an inner bearing driving member for transforming a rocking movement from said driving means into rotational movement for transmission to said inner bearing, and an inversion means for rotating said inner bearing in a direction opposite to the rotational direction of said pivot shaft, whereby the driving force is transmitted from said driving means into driving forces for both the first and second driving apparatuses respectively;
• wherein the inclination of said pivot shaft relative to said axis of said inner bearing is set so that an attack angle of a wiper blade, carried by said wiper arm, with respect to a surface of the windshield glass which is wiped by said blade, is at an angle within a range of .+-.5 degrees.

• an inner bearing rotatably supported in said holder so as to rotate relative to the vehicle body about the axis of said inner bearing, the inclination of said pivot shaft relative to the axis of said inner bearing being set so that an attack angle of the wiper blade with respect to the glass surface which is wiped by said blade, at tilting angle within a range of .+-.5 degrees;
• a pivot shaft for reciprocatively pivoting a wiper arm fixed thereto by reciprocatively rotating about the axis of said pivot shaft;
• and
• a rotating means comprising a lever crank means coupled to a driving means, and recprocatively rotate said inner bearing in a same direction as the direction of the reciprocative rotation of said pivot shaft with said pivot shaft, said lever crank means comprising a first driving apparatus having a pivot shaft driving member for transforming the rocking movement from said driving means into rotational movement for transmission to said pivot shaft, second driving apparatus having an inner bearing driving member for transforming the rocking movement from said driving means into rotational movement for transmission to said inner bearing and a same direction rotating member for rotating said inner bearing in the same direction as the rotational direction of said pivot shaft, and the driving force being transmitted from said driving means into driving forces for both said first and second driving apparatuses respectively.
