Claims

[Claims for Utility Model Registration] (1) A link connecting rod that reciprocates as the wiper motor rotates is connected to one end of the crank arm via a ball joint, and is supported by a pivot retainer and swings the wiper arm back and forth. A serration shaft provided on the pivot is fitted to the other end of the crank arm, and its tip is crimped and fixed, so that the reciprocating movement of the link connecting rod is transferred to the reciprocating rotation of the pivot via the crank arm. In a vehicle wiper device that converts motion into dynamic motion,
A wiper device for a vehicle, characterized in that a boss portion is formed by drawing on a portion of the crank arm into which the serration shaft portion of the pivot is fitted, and the serration shaft portion and the boss portion are crimped and fixed. Pivot-crank arm connection structure. (2) Utility model registration claim No. (1) characterized in that a serration is formed on the inner circumferential surface of the boss portion to form a pair with the serration shaft portion of the pivot.
Pivot-crank arm connection structure of the wiper device for a vehicle as described in . (3) The pivot-crank arm connection of the wiper device for a vehicle according to claim 1 or 2, wherein the crank arm is provided with a rib portion on its outer periphery. structure.
