To provide a latch device imparted with hobby sense and unexpectedness and also excellent in operational feeling.

A handlebar 3 is disposed at a normal position and a lock case 4 is disposed above or below the handlebar 3. Meanwhile, a drive arm 7 and a driven arm 15 which are of same length are attached to a rotary shaft of the handlebar and to a retractor shaft of the lock case, respectively. On the other hand, a connection rod 16 parallel to a free side edge 2 of a door is guided so as to be vertically movable, to an opposite side of the free side edge of the door with respect to the handlebar 3 and the lock case 4. The free ends of the drive arm 7 and the driven arm 16 are link-coupled with the upper and lower ends of the connection rod 16, respectively, in a positional relationship that makes the drive arm parallel to the driven arm.
