Next, a method for assembling the guide member 4 into the case member 3 will be described with reference to FIGS. 1 to 3. The method is such that the space between the locking portions 3k, 3k of the case member 3 is slightly widened, and the elastic member 5 is projected rearward on the standing surface 4b of the guide member 4. As it is, the protrusions 4e, 4e of the guide member 4 are positioned on the engaging portions 3k, 3k by inserting the protruding surface 4b into the opening S of the case member 3, and subsequently, the engaging portion 3k. , 3k are bent so that the distance between them is narrowed, and the protrusions 4e, 4e may be inserted into the openings 3m, 3m of the locking portions 3k, 3k. In this state, the rear end of the elastic body 5 contacts the inner surface of the back plate 3g in the case member 3 to urge the guide member 4 forward, and the front end of the guide member 4 moves. The push button portion 4 is placed in the opening 3b of the case member 3. The insertion position of the tongue 10 is a position along the front surface of the guide member 4 from the opening S at the side end of the case member 3.

Subsequently, a state in which the tongue 10 is inserted into and engaged with the buckle body 2 will be described with reference to FIG. When the tongue 10 is inserted along the front surface of the guide member 4 through the opening S at the side end portion of the case member 3, the tongue 10 is moved forward when the upper and lower end surfaces of the tongue 10 are inserted into the case member 3. It is inserted while being restricted by the stepped portions 3c, 3c of No. 3. If this insertion is continued, first, the tip of this tongue 10 contacts the slope of the projection 4f of the guide member 4 to push down this guide member 4, and if this insertion is continued, the tongue 10 is formed. The projection 4f drops into the opening 10b that is open, and the guide member 4 is pushed back forward by the elastic body 5. In this state, the further movement of the tongue 10 in the insertion direction is restricted because the projections 10c, 10c of the tongue 10 contact at the inlet of the case member 3. In this state, the movement of the guide member 4 in the vertical direction is restricted by the upper and lower two convex protrusions 3h, 3h of the case member 3, and the rear end ( The movement of the case member 3 in the direction of the back plate portion 3g) is restricted so as to contact the protrusions 3h, 3h. For this reason, the locked state is not unlocked only by moving the tongue 10.

The locked state can be released by pushing the push button 4c backward as shown in FIG. That is, when the guide member 4 is retracted rearward (in the direction of the back plate portion 3g of the case member 3) by this operation, the protrusion 4f of the guide member 4 engaged in the opening portion 10b of the tongue 10 is opened. The tongue 10 can be pulled out by detaching from the inside of 10b to the rear.

It should be noted that the orientation such as the front-back direction calculated in the above description is based on the assumption that the push button 4c is directed to the front.
