An elongated frame in which the pair of pivot holders are connected to each other and the drive source is fixed;
A vehicle wiper device comprising:
The frame is provided on the outer peripheral surface thereof with a frame side fitting portion which is convex or concave in a direction perpendicular to the longitudinal direction of the frame so as to be continuous along the longitudinal direction.
The said drive source has a drive source side fitting part fitted with the said frame side fitting part, The wiper apparatus for vehicles characterized by the above-mentioned.

  Here, for example, in order to fix a drive source (motor) to a frame, a fastening hole may be provided to the frame, and by inserting and fastening a fastening member such as a bolt into the fastening hole. It is known to fix the drive source to the frame. In such a configuration, the relative position in the longitudinal direction between the drive source and the frame is determined when the fastening holes are provided in the frame, so the versatility of the frame itself is low, and the mountability to the vehicle may be affected. There is.

  Therefore, by adopting the configuration of the above-mentioned Supplementary Note 1, the position of the drive source in the longitudinal direction of the frame can be easily adjusted by relatively sliding the frame and the drive source in the longitudinal direction of the frame. This can improve the mountability to a vehicle.
