Abstract
Herein disclosed is a wiper which can selectively assume a "semi-concealed mode" and a "full-concealed mode". The wiper comprises an output gear housed in a case, an output shaft having one end to which a motor arm is secured, a wiper arm assembly including a connecting rod which is pivotally connected to the motor arm, a first mechanism for transmitting rotation of the output gear to the output shaft, a bushing rotatably housed in the case and having an eccentric bore through which the output shaft is rotatably passed, a second mechanism for locking the bushing to one of the case and the output gear while changing relative angular positioning between the bushing and the output gear, and a push button arranged on the case and actuating the second mechanism when manipulated.
