[0056] The coil spring 101 is disposed between the button body 100 and the spring disposing portion 35 of the front cover 30, thereby biasing the button body 100 upward (in the direction in which the tongue body 80 is pulled out).

[0057] Then, the connecting pin 61 is inserted into the locking hole 122 to connect the operating piece 60 and the button body 100, and the engaging portion 36 of the front cover 30 is engaged with the engaged portion 43 of the back cover 40, thereby completing the buckle device 10.

[0058] The function and operation of the buckle device 10 of this embodiment will be described below.

[0059] As shown in FIGS. 2 and 18, the engaging portion 84A of the right tongue body 81A and the engaging portion 84B of the left tongue body 81B are engaged and integrated to form a single tongue body 80.

[0060] The integrated tongue portions 85A, 85B are inserted into the opening of the tongue-mounted body 50. When the tongue portions 85A, 85B come into contact with the pair of abutment pieces 53, 53, the operating piece locking portions 56 located below the shaft 54 ​​of the pair of abutment pieces 53, 53 move away from each other against the biasing force of the coil spring 57.

[0061] When the operating piece locking portion 56 moves away, the lock between the operating piece 60 and the pair of contact pieces 53, 53 is released. When the lock between the operating piece 60 and the pair of contact pieces 53, 53 is released, the operating piece 60 moves upward due to the biasing force of the coil spring 63. Accordingly, the biasing force of the coil spring 101 is also applied, and the button body 100 also moves upward.

[0062] At this time, as shown in Figures 1 and 19, the second display section 112, which was visible through the display window 33, moves upward and is hidden by the bottom wall 32 of the bottomed recess 31, and the first display section 113 moves from the bottom and becomes visible through the display window 33.

[0063] Furthermore, the tongue locking portion 55 and the locking portion 88 of the tongue body 80 are locked by the pair of contact pieces 53, 53.

[0064] When releasing the engagement between the buckle body 20 and the tongue body 80, the button body 100 is moved downward, causing the operating piece 60 to move downward against the biasing force of the coil spring 63, and the biasing force of the coil spring 57 brings the operating piece locking portions 56 of the pair of abutment pieces 53, 53 closer together, thereby locking the operating piece 60 with the pair of abutment pieces 53, 53, and returning to the state shown in Figure 18 in which the engagement between the tongue locking portion 55 and the locking portion 88 of the tongue body 80 is released.

[0065] At this time, the first display section 113, which was visible through the display window 33, moves downward and is hidden by the bottom wall 32 of the bottomed recess 31, and the second display section 112 moves from the upper side and becomes visible through the display window 33.
