PROBLEM TO BE SOLVED: To provide a lock device capable of exerting waterproof performance over a long period of time. SOLUTION: This lock device comprises: a locking body 4 which releases the locked state of restraining the movement of a locking object 3 by connecting an attachment/detachment connecting end 1 to a lock body 2, by disconnecting the connecting end 1; a locking portion 6 which is arranged in the lock body 2, and which maintains the locked state by locking a portion 5 to-be-locked of the locking body 4; and an elastic seal body 8 for sealing a locking-body inserting hole 7 which allows the insertion of the portion 5 of the locking body 4. The elastic seal body 8 is fixed to either of the lock body 2 and the locking body 4; and a seal-body fitting recess 9, which is externally fitted to the elastic seal body 8 in the locked state so as to cover a peripheral edge of the elastic seal body 8, and which applies a predetermined sealing pressure to the elastic seal body 8, is formed in the other one of the lock body 2 and the locking body 4.
