摘要：In a key cylinder (10) a stopper plate (34) is pressed into an imposing hole (32)
of a rotor (28), latching to a body (12) and also intruding into engagement grooves (54) of a second sleeve (52). When an authentic key is inserted into the rotor (28) and rotated, a first sleeve (44) is not rotated, and a second sleeve (52) is rotated through the stopper plate (34). When a false key is inserted into the rotor (28) the first sleeve (44) rotates and the second sleeve (52) is slid to the rear by slide bars (50), therefore the stopper plate (34) separates from the engagement grooves (54), and the second sleeve (52) is not rotated. The stopper plate (34) has the function of being able to stop the movement of the rotor (28) in the forward-rearward direction, and also the function of making the second sleeve (52) rotatable by the rotation of the rotor (28), and so the construction of the key cylinder is simplified.
