Next, the operation of the gate lock configured as described above will be described. The fact that the handle shaft 2a of the operation handle 2 and the shaft portion 5a of the latch 5 are on the same axis center (see FIG. 1) is similar to a conventional gate lock, and is easy for a person who is used to the conventional gate lock to operate. There is no sense of incongruity. When the horizontal operation handle 2 is rotated downward by a substantially predetermined amount, the rotation amount is expanded by the group of speed-increasing gears (gears 28, 32, 33, 34), and the latches engaged with the catches 6 are provided. The lever 5b of No. 5 separates from the receiving plate 6 and stands up.
