The second member leg piece convex portion 37 is fitted into the positioning groove portion 26 of the first member groove portion 25.

  According to this configuration, in the second coupling member 30, the second member groove portion 36 is fitted into the main body protrusion 16, and the second member leg piece convex portion 37 is inserted inside the coupling port 13. That is, since the second coupling member 30 is fitted to the main body coupling portion 11 by fitting two opposite directions, the direction X in which the first member 20 is coupled to the coupling port 13 and the front and back surfaces (front and rear) ) In the direction intersecting with the main body coupling portion 11 is maintained. Therefore, the coupling state between the buckle body 10 and the second coupling member 30 can be made firm.

The second member leg piece recess 40 fits into the first member protrusion 28 of the first member groove 25.

  According to this configuration, since the width of the first member groove portion 25 is narrowed by the first member protrusion 28, there is no space for a finger or the like to be sandwiched. Therefore, it is safe when the second coupling member 30 and the first coupling member 20 are coupled.

  According to this embodiment, the main body coupling portion 11 of the buckle main body 10 has a substantially disk shape, and the main body outer peripheral surface 15 is curved from the coupling port 13 to the main body protrusion 16. According to this configuration, when the first coupling member 20 is coupled to the main body coupling portion 11, the edge of the open end 38 of the second member groove portion 36 (the second member inner peripheral surface 35) is curved in the main body coupling portion 11. The main body protrusion 16 of the main body coupling portion 11 is guided and received in the second member groove portion 36 while contacting the outer peripheral surface 15 and sliding. Therefore, the buckle body 10 and the second coupling member 30 can be easily coupled.
