<p>PROBLEM TO BE SOLVED: To provide a portable lock key capable of locking/unlocking only to rotate a grip member in either of the right or left direction even when phases are not matched between an inner engaging body and an outer engaging body, for example.SOLUTION: A portable lock key comprises: a key body supported to be rotatable in a right and left direction at a predetermined position to a grip member and having an inner engaging body at a key shaft rear end part; and a trigger member provided to be movable in a shaft direction toward the key shaft rear end part at a front side from the inner engaging body, whose protruding outer end part is urged by spring force of a return spring packaged inside the grip member to be protruded by a predetermined amount from an apical surface of the grip member, and having an outer engaging body at a fitting insertion inner end part positioned in the grip member. When the grip member is held and the key body is inserted into a keyhole, the apical surface of the trigger member is retreated against the spring force of the return spring while being in contact with a periphery of the keyhole, and the grip member, the trigger member, and the key body are integrally coupled to be rotated interlocking with each other on a condition that the outer engaging body and the inner engaging body are engaged with each other in a clutch state.</p> |
