Title:
Cylinder lock
Document Type and Number:
Japanese Patent JP6000169
Kind Code:
B2
Abstract:
In a cylinder lock in which a pivot member is pivoted in response to pivoting by a legitimate mechanical key inserted into a key hole, a first rotor (20) is linked to an outer cylinder (15) relatively non-pivotably but movably along an insertion direction (18) of a mechanical key (11), and a second rotor (22) abuts against the first rotor (20) from a side opposite to a rotor-receiving part (19) provided on one of a housing (14) and the outer cylinder (15) and is linked to a pivot member (21) relatively non-pivotably but movably along the insertion direction (18), and during pivoting of the outer cylinder (15) in response to an unauthorized pivoting operation of an inner cylinder (13), the first rotor (20) and the second rotor (22) move so as to detach from the rotor-receiving part (19) due to a cam mechanism provided between the first rotor (20) and the housing (14), thereby releasing engagement of the inner cylinder (13) with the second rotor (22) linked to the pivot member (21) relatively non-pivotably. This enables theft resistance to be obtained with a simple and small-sized structure.
