An intermittent driving apparatus for a rotary window cleaner comprises a first wiper (2) which is connected to a rotating shaft (10) of a first motor (8) and is rotatably disposed on a front window (1), a second wiper (3) which is connected to a rotating shaft (11) of a second motor (9) and is rotatably disposed on a front window (1) adjacently to the first wiper (2), and an electronic control circuit having brush boards (18, 20) of two motors connected to each other so that the second motor (9) is rotated at a predetermined time after the first motor (8) is rotated. The electronic control circuit includes a signal generating circuit (30) for repeatedly sending signals to the brush board (18) of the first motor (8) at fixed time intervals, and a brake mechanism for stopping the two wipers at the start position for a predetermined time every one rotation.
