Claim:
A wiper device comprising: first and second pivot shafts, each having a distal end to which a wiper arm is fixed; first and second pivot holders fixed to a vehicle body, which pivotally support the first and second pivot shafts and include first and second attachment shafts, respectively; a hollow frame formed by a hollow member, which couples the pivot holders to each other; a drive source fixed to the hollow frame; a link rod which transmits drive force of the drive source to the first and second pivot shafts; wherein the hollow frame includes first and second coupling-fixing portions, a drive source fixing portion and first and second crank portions; the drive source fixing portion is arranged between the first and second coupling-fixing portions and fixed with the drive source; the first and second attachment shafts are respectively crimped and fixed to the coupling-fixing portions in a state inserted into the corresponding coupling-fixing portions along axes of the coupling-fixing portions, and the axes of the first and second coupling-fixing portions lie along a straight line; and the hollow frame is bent so as to arrange the drive source fixing portion spaced apart from the first and second pivot holders in a direction extending from the distal ends towards basal ends of the pivot shafts; the first crank portion, which is bent to be crank-shaped and extends between the drive source fixing portion and the first pivot holder; the second crank portion, which is bent to be crank-shaped and extends between the drive source fixing portion and the second pivot holder; and the first crank portion includes first and second bent sections respectively bent about bending axes, which are not parallel to each other; and the second crank portion includes third and fourth bent sections respectively bent about bending axes, which are not parallel to each other.
