<p>PROBLEM TO BE SOLVED: To provide a lock device which can be easily picked up even when it has dropped.SOLUTION: A lock device includes: a key 10 having a key head 11 and an insertion part 12; and a key head cover 20 for covering the key head 11. A breakthrough 24 allowing a finger to be inserted is formed in the key head cover 20. The key head cover 20 is configured so as to form a clearance S allowing a finger to approach between an arbitrary smooth surface G and a formation portion when the key head cover 20 is placed on the arbitrary smooth surface G. It is preferable that the lock device is provided with: a case body 21 which stores the key head 11 of the key 10 in its tip 211 and has a breakthrough 24 formed in its base end part 212; and a projection 25 which is formed on each of the surface and the rear face of the case body 21, and in which a crown 25a is positioned on the base end part 212 side more than the center of gravity of the whole device.</p> |
