Claim:
A wiper assembly including a shaft which is connected to a driving motor via a linkage and rotated by the driving motor, an arm head including a shaft hole into which the shaft is inserted, and an arm having one end combined with the arm head by a rotating shaft and rotatable about the rotating shaft and the other end combined with a wiper blade which wipes a window of a vehicle, the wiper assembly comprising: a locking member which is supported by the arm head and movable between a locking location where the locking member is locked in the shaft so that the shaft cannot be separated from the shaft hole of the arm head and an unlocking location where the locking member is unlocked, from the shaft so that the shaft can be separated from the shaft hole of the arm head; and a locking member moving unit which moves in response to a rotation of the arm so as to move the locking member between the locking location and the unlocking location, wherein: the locking member moving unit includes protrusions included in the locking member, pulling portions included in the arm, and a spring which biases the locking member so that the locking member is placed in the locking location; as the arm is pivoted about the rotating shaft such as to be distant from the window of the vehicle, the pulling portions of the arm catch and pull the protrusions of the locking member so that the locking member is placed from the locking location into the unlocking location; and as the arm is pivoted about the rotating shaft such as to be closer to the window of the vehicle, the locking member slides such as to be placed from the unlocking location into the locking location.
