PROBLEM TO BE SOLVED: To provide a cylinder lock which is prevented from erroneous directional connection between an internal cylinder lock mechanism and an output shaft when assembled together. SOLUTION: The invention is applicable to the cylinder lock, according to which the internal cylinder 14 is installed in a front external cylinder, a connection shaft 33 transmits rotational torque of the internal cylinder 14, and the output shaft 36 is installed in a rear external cylinder portion 13 to transmit rotational torque via a joint block 38 to a joint cam 39, based on the rotational torque transmitted via the connection shaft 33 from the internal cylinder 14. A shaft hole 32b is formed in the rear of the internal cylinder 14, and has almost the same shape as that of a front end of the connection shaft 33, into which the connection shaft 33 is inserted. A shaft hole 36a is formed in the front of the output shaft 36, and has almost the same shape as that of the other end of the connection shaft 33, into which the connection shaft 33 is inserted. The shapes of the shaft hole 32b and the shaft hole 36a are non-point-symmetrical about the rotation axis of the internal cylinder 14 and the output shaft 36. COPYRIGHT: (C)2009,JPO&INPIT
