[0010]

However, the conventional dust bag holder has the following drawbacks because the belt stopper 2 is adhesively fixed to the belt base end portion.

(I) Since the bonding step is required at the stage of manufacturing the holder, the manufacturing cost becomes high.

(Ii) If either one of the belt 1 and the stopper 2 is damaged, the whole must be replaced, which is economically wasteful.

(Iii) The belt 1 has a winding tendency during repeated use, and the restoring force to the single winding state decreases.

In this case, since the belt stopper 2 is adhesively fixed to the belt 1, only the belt 1 cannot be turned over and reused. For this reason, the life is short, and economical waste is large in this respect as well, and in the case of a plastic holder, there is a problem in terms of plastic pollution.

Therefore, according to the present invention, a belt stopper for a dust bag holder, which can reduce the cost by omitting the bonding step at the manufacturing stage, has no economical waste, and can further improve the life of the belt. A tool and trash bag holder is provided.

The belt stopper according to any one of claims 1 to 3, wherein the base end portion of the belt is engageable with the first protrusion in a disengageable manner, and the tip end portion is engageable with the second protrusion. Second engaging holes for engaging are provided respectively.

[0019]

According to the above construction, since the belt and the belt stopper are detachably coupled with each other through the engaging holes and the protrusions, this coupling operation can be easily performed by the user. Therefore, these bonding steps at the manufacturing stage are unnecessary.

If one of the belt and the stop is damaged, only this one member can be replaced.

When the belt has a winding tendency, only the belt can be turned over and reused. Therefore, it can be used semipermanently until the original life of the belt.

According to the second aspect of the present invention, the guide portion causes the proximal end portion of the belt to be in close contact with the inner surface of the outer wall of the stopper, and the close contact between the belt and the stopper surely holds the engaging action. Therefore, even though it is detachable, the coupling state between the belt stopper and the belt becomes stable.

In addition, in the double winding state, the guide portion secures a gap between the belts, and the frictional resistance between the belts is reduced. Therefore, the operation of restoring to the single winding state (expansion of the belt) is performed reliably and smoothly.
