PURPOSE:To allow a wiper blade to be stopped at an optional position by constituting a drive motor feed switch with a terminal deenergizing the wiper blade immediately before it reaches a lower reverse position and a terminal deenergizing it immediately before the operation of a connection means becomes possible. CONSTITUTION:When a connection means 13 is rotatably fitted to a crank shaft 10 on a crank arm 6 rotated by a motor 8 of a wiper device through a drive shaft 7, a rance 15 of the connection means 13 is moved, and a lug 18 on the rance 15 is coupled with a stopper piece 20 provided on the end of a wiper link rod 5, the relative rotation of an eccentric bush 11 against the rod 5 is blocked. In this case, the motor 8 is energized through a switch 28, which is constituted with a switch operation section 29 switching to the high speed, low speed, and stop, a stop position selection operation section 30 setting a stop at the upper and lower reverse positions, and cam plates 31, 32 interlocked with the motor 8. |
