[Problems to be solved by the device]

 However, in the shoulder band attachment described in Japanese Utility Model Laid-Open No. 6-19539, the upper part of the rocking attachment member to which the connecting ring connected to the shoulder band is attached is the upper side of the attachment plate member and the lid member. It projects from the opening formed in the section. Therefore, when the user carries the device on his / her back and attaches it, a part of the swing mounting member is pressed against the peripheral wall that forms a boundary with the opening, so that the peripheral wall and the swing mounting member are greatly consumed and the useful life is increased. Has the drawback of being shorter. Also, when the backpack is carried on the back, the rocking attachment member is pulled in the front direction of the backpack surface of the backpack so that a part of the rocking attachment member is pressed into contact with a part of the upper side of the lid member that is opened. Therefore, there is an unfavorable problem that those parts are also consumed.

Further, in the shoulder strap attachment described in Japanese Utility Model Publication No. 3-55293, the slider is normally in the locked state, and the slider does not move unless the slider is released, so that the operation is troublesome. In addition, since the locking position is limited to the position of the preformed kerf, there is a problem in compatibility with the physique of the user. Further, in the present invention, since the main body is attached to the back side of the back plate such as the school bag, the back plate such as the school bag is provided with a fastening hole for mounting the back strap mounting device and a slider. A window hole must be provided to move the belt to the left and right, which complicates the manufacturing process of the backpack belt.

The present invention has been made in view of the above circumstances. The swing mounting member can swing freely in the left-right direction, and wear of the mounting board member, the lid member, and the swing mounting member is reduced. The purpose of the present invention is to provide a shoulder band attachment for a shoulder bag that has a long service life.

[Effect of the invention]

 As described above in detail with reference to the embodiments, according to the present invention, the pair of sliders connected to the left and right holder bands are provided with a pair of sliders. Since these shoulder bands are biased toward the side, the possibility that each of these shoulder bands will be excessively pushed to the left and right and will be in a biased state will be completely eliminated. Further, since the pair of sliders can freely slide in the left-right direction, it is necessary to adjust the position of each slider one by one when extra force is applied to each shoulder band in the left-right direction. Since it can be received with moderate elasticity, not only when carrying a new shoulder bag, but also when carrying it, this carrying state is kept extremely stable, which results in In addition, it is easy to carry on your back.

Further, in the present invention, each slider is mounted on the front surface of the mounting board member, and a part of each swinging mounting member is assembled to the lid member without protruding to the outside. Since it is housed inside, the pressure contact with the peripheral wall portion of the mounting board member is eliminated even when the swing mounting member swings to the left and right, respectively, and each swing mounting member and peripheral wall portion are Wear is avoided. Further, since each swing mounting member is formed in a plate shape parallel to the inner surface of the mounting board member, each slider is pulled in the front direction, and accordingly, each swing mounting member is attached to the inner surface of the mounting board member. Even when abutting against, the applied force is dispersed without concentrating on one point, and therefore, the consumption of each swing mounting member and the mounting board member is much reduced as compared with the prior art.

Furthermore, when a moving groove is formed on the mounting board member, the design of the moving groove itself and the design of each slider formed so as to slide along the moving groove are unfavorable. This is favorable and has the effect of improving the designability as a shoulder band attachment.

Further, the attachment of the shoulder bag to the back plate is made stronger by holding the back plate with a holding member. Further, in the shoulder band attachment according to the present invention, the mechanism for sliding each slider is entirely housed inside the attachment plate member assembled with the lid member, so that the back plate corresponds to each fixing hole. It suffices to provide a hole through which each fastening member penetrates, and the problem in the shoulder bag manufacturing process can be solved.
