して、駆動板９を図示左方に変位している。 The driving plate 9 is engaged with a guide hole 8 formed in the side plate 1 and is freely displaceable in the left and right directions in the drawing.
In the illustrated position, the first bent part 9a engages with the arm 7a, the second bent part 9b has an opening in which the bolt rod 4 is loosely fitted, and , the drive plate 9 has a third bent portion 9c.
is formed, and the bent portion 9c is located close to the front plate 2 in the illustrated locked position, and a spring 12 is disposed between the bent portion 9c and the support member 5, and the drive The plate 9 is displaced to the left in the figure.

な解錠状態になる。 Since it basically has this configuration,
When the hub 7 is rotated in the direction of the arrow A in FIG. 2 by an external operation, the arm 7a of the hub 7 displaces the first bent portion 9a of the drive plate 9 to the right in the diagram.
The driving plate 9 is displaced in the direction of the arrow B, and at the same time, the spring 6 is compressed by the second bent portion 9b, and the spring 12 is compressed by the third bent portion 9c.
As the drive plate 9 moves to the right, the bolt 3 is inserted into the opening 2a of the front plate 2, resulting in an unlocked state as shown in the second figure.
なお図示符号１４は、このときボルト３の後退
量に規制するストツパである。 Note that the reference numeral 14 in the figure is a stopper that restricts the amount of retraction of the bolt 3 at this time.
