The partition bar 4c connecting d 'is traversed. A first slit 42 through which the belt passes is defined between the partition bar 4c and the upper wall 4a, and a second slit 44 through which the belt passes is defined between the partition bar 4c and the lower wall 4b. Lower wall 4
A flexible first pad 20 made of rubber or sponge forming a part of the shoulder pad is attached to the outer surface of the pad b.

The second belt loop 6 has the same structure as the first belt loop 2 as shown in FIG. The outer surface of the lower wall 6b of the second belt loop 6 is also provided with a flexible second pad 22 made of rubber or sponge which forms a part of the shoulder pad. The third belt loop is shown in FIG.
As can be seen from (a), except that the length is shorter than the first belt loop 4 and the second belt loop 6 and has no partition bar and pad, it has the same structure as the first belt loop 2 and the second belt loop. It is a box-shaped hollow body.

Returning to FIG. 3 (a), the belt 2 extends through the belt length adjusting mechanism 12 to
And passes through the third belt loop 8. Next, the second belt 6
After passing through the slit 64, it is rewound by the partition bar 6c, passes through the first slit 62 defined between the partition bar 6c and the upper wall 6a, and heads toward the third belt loop 8. Next, the belt 2 that has passed through the third belt loop 8 returns to the first belt loop 2, and after passing through the second slit 44 again,
It is rewound by the partition rod 4c and passes through the first slit 42 toward the third belt loop 8. Next, the belt 2 passes through the third belt loop 8 and returns to the second belt loop 6. The belt 2 extends through the second slit 62 of the second belt loop 6 and is connected to the eggplant ring 16 at the second end 2Y. Here, it should be noted that since the belt 2 reciprocates once and half through the first belt loop 4 and the second belt loop 6, the belt 2 is tripled between the first belt loop 4 and the second belt loop 6. Is that the belt portions 2a, 2b, and 2c that overlap each other exist.

In order to pull out the belt 2 shown in FIG. 3A, the third belt loop 8 may be pulled upward. Alternatively, the first belt loop 4 and / or the second belt loop 6 may be pulled upward. By pulling up the first and second belt loops while approaching them, the belt can be more smoothly pulled out. By this operation, tension is applied to the belt, and the belt ends 2X and 2Y are fixed to the bag (not shown) via the rings 14 and 16, so that the belt tension is reduced by the partition rod 4c of the first belt loop 4.
And acts on the partition bar 6c of the second belt threader 6 as shown in FIG.
The first belt loop 4 and the second belt loop 6 are moved toward the third belt loop 8 as shown in FIG. At the same time, the uppermost belt portion 2c is pulled out of the second belt loop 6, and the lowermost belt portion 2a is pulled out of the first belt loop 4.

Further, when the third belt loop 8 is lifted upward, the first belt loop 4 and the second belt loop 6 are brought into the third belt loop.
The uppermost portion 2c of the belt is in the second position until it contacts the belt loop 8.
The belt is pulled out from the belt loop 6, and the lowermost portion 2 a of the belt is pulled out from the first belt loop 4. Then, as shown in FIG. 3 (c), the first belt loop 4 and the second belt loop 6
Once in contact with the belt loop 8, the belt will not be drawn any further. In this state, the pads 20 and 22 of the first and second belt loops 4 and 6 come into contact to form an integral shoulder pad.

It should be noted here that the belts 2a, 2b, and 2 which have been folded three times in the state of FIG.
3c is shortened as shown in FIG. 3 (c), so that most of the triple folded belts 2a, 2b, and 2c are pulled out of the first and second belt loops 4, 6. It has been. That is, it is possible to draw out the belt 2 having a length close to about three times the length of the shortened state of the belt 2. The change of the belt from FIG. 3A to FIG. 3C is performed instantaneously and smoothly. Therefore, for example, when the user holding the handle of the bag wants to use the shoulder belt, the belt 2 can be instantaneously used as the shoulder belt by pulling up the belt 2 from the bag body.

To return the belt 2 once pulled out as shown in FIG. 3 (c) to a shortened state as shown in FIG. 3 (a), the first and second belt loops 4, 6 are grasped. FIG.
