 An example of a conventional buckle is shown in FIGS. This buckle is composed of a belt 40 having a large number of irregularities 41 regularly arranged on the back surface, and a buckle body 11 having a buckle device 33 for locking the rear end portion 10b of the belt 40 at an arbitrary position. Buckles are used. In such a buckle, a plate-like body 35 is projected on either the left side or the right side of the buckle body 11 having the buckle device 33 with the protruding piece 23 projected in the central portion, and the belt attachment frame is attached to this. 36 is formed, and the rear end portion 10b of the belt 40 is attached to the belt attachment frame 36 to form a buckle. In the figure, reference numerals 21 and 22 denote knobs, and 40c denotes an attachment portion for attaching the belt 40 via attachment means such as sewing of the belt 40 to the attachment frame 36.

The buckle device 33 used here is composed of a belt 40 and a buckle body 11, as shown in cross-sectional views in FIGS. 6 and 7, and the buckle body 11 is provided with a projecting piece 23. And a backing plate 30 and a spring 25. As shown in the figure, the buckle main body 11 is provided with a belt insertion port 12 penetrating the belt 11 on the left and right sides toward the front side, and a groove 13 is provided in the longitudinal direction on the back surface of the belt insertion port 12 and a belt is formed on the groove bottom 13a. A protrusion piece through hole 15 communicating with the insertion port 12 is provided. The operating rod 20 is formed to be longer than the longitudinal length of the buckle main body 11, and is provided with a protruding piece 23 that can protrude from the protruding piece through hole 15 into the belt insertion opening 12 on the front side. Then, by fitting the operating rod 20 into the groove 13 of the buckle body 11 so as to be operable in the front and back directions, the protruding piece 23 is fitted in the protruding piece through hole 15 and fixed to the back surface of the buckling body 11. A spring 25 is interposed between the backing plate 30 and the operating rod 20 so that the tip of the projecting piece 23 is constantly elastically projected into the belt insertion opening 12.

In this buckle, the front end portion 40 a of the belt 40 is inserted into the belt insertion opening 12 of the buckle, and is passed through the buckle. When the locking unevenness 32 of the belt 40 reaches an appropriate position, the protruding piece 23 of the buckle device 33 engages with the locking unevenness 32 of the belt 40 to lock and fix the belt 40.

[Problems to be solved by the device]

 In such a conventional buckle, since the attachment frame 36 for attaching the rear end portion 40b of the belt 40 projects substantially parallel to the buckle body 11, when the rear end portion 10b of the belt 40 is attached, The thickness of the belt 40 is generated when the belt 40 is attached, and the belt 40 bulges. In this state, the tip portion 10b of the belt 40 inserted through the buckle overlaps with the belt 40 of the attachment portion at the exit portion of the buckle and floats up. When the belt 40 bulges in this manner, the buckle has an inclined shape, which is not only unattractive in appearance but also causes a problem that the protruding piece 23 easily comes off.

Further, since the conventional buckling device 33 is located at the center of the buckle, it means that the belt 40 is squeezed at the center, so that the buckle is not of the type adapted to the usage convention.

The present invention solves the above problems, and an object of the present invention is to provide a belt bag formed so that the belt does not float up at the belt outlet when the belt tip is inserted into a buckle. .

[Means for Solving the Problems]

 The buckle for a belt according to the present invention is a buckle body including a belt having locking and recessing protrusions arranged in parallel on the back surface, and a buckle device for attaching the rear end of the belt and engaging with the locking and recessing protrusions. In the belt buckle consisting of the and, a buckle device with a protruding piece for locking the belt interlocking with the pressure plate is attached to the root of the buckle body, and the rear end of the belt is attached. The mounting part to be attached should be projected, the mounting part should be slanted downward from the root part, and it should be tapered, and a support rod for mounting the rear end part of the belt should be provided at the tip part. Is characterized by.

According to the present invention, the belt mounting portion of the buckle body is slanted downwardly and is tapered, and the belt rear end portion is attached to the belt mounting portion, so that the belt tip portion is inserted into the buckle. However, the front end of the belt does not float up at the rear end of the attached belt.

Further, since the buckle body is fitted with the buckle device having the protruding piece, when the belt tip is inserted, the buckling body is attached to the engaging concave and convex portions by the elastic pressure of the protruding piece. Since it is locked by locking, the arbitrary position can be freely selected and the protruding piece does not come off. To release the lock, the buckle device of the base body may be operated to release it. When the belt floats up, the attachment part bulges out and the belt is not in good working condition.
