2. Description of the Related Art A hose with a mouthpiece obtained by an assembling machine is
As shown in FIG. 3, the insertion portion 91a of the base 91 is inserted into the opening 90a of the cylindrical tube 90, and the peripheral wall of the opening 90a is covered with a collar 92 for preventing the insertion portion 91a from coming off. When this hose with a mouthpiece is adopted for a fuel hose, for example, the collar 92 is covered with the front end of a protector 93 coaxial with the tube 90, thereby preventing damage due to interference with other structures in a vehicle, for example. At the same time, the collar 92 is prevented from coming off, and further the insertion portion 91a is further prevented from coming off.

Conventionally, as a method of covering the front end of the protector 93 on the collar 92 of the hose with a mouthpiece, as shown in FIG. 4, an operator attaches the rear end of the protector 93 to the tube 90 of the hose with a mouthpiece. By pressing along the direction of the arrow, the front end of the protector 93 is attached to the collar 92.

[0004]

However, the protector 9
No. 3 is given only an inner diameter slightly larger than the outer diameter of the tube 90. Therefore, the protector 93 is attached to the tube 9
It is possible to slide relatively smoothly with respect to 0, but it is difficult to slide with respect to the collar 92 unless the diameter is expanded.

Therefore, if the operator manually wears the protector 93 as in the conventional method, the protector 93 must be expanded in diameter by the pressing force of the operator, which requires labor and workability. It wasn't enough. In addition, protector 9 manually
If 3 is put on, the relative position with respect to the collar 92 is likely to be displaced and the product is likely to be varied. The present invention has been made in view of the above-mentioned conventional circumstances, and an object of the present invention is to provide a protector mounting device that is less likely to cause variations in products under suitable workability.

[0006]

The protector mounting device of the present invention uses a hose with a cap in which an insertion portion of a cap is inserted into an opening of a cylindrical tube and a collar is mounted on a peripheral wall of the opening. A protector mounting device for mounting a front end of a protector coaxial with a tube on the collar, the protector holding member for slidably holding the protector, and an inside of the protector from an opening at a rear end of the protector. The front end of the protector is attached to the collar by pressing the rear end toward the collar while expanding the diameter of the protector with air interposed between the peripheral surface and the outer peripheral surface of the tube. And a diameter-expanding pressing member for allowing the diameter to be increased.

[0007]

In the protector mounting device of the present invention, the diameter expansion pressing member expands the diameter of the protector by interposing air between the inner peripheral surface of the protector and the outer peripheral surface of the tube through the opening at the rear end of the protector. To do. Then, in this state, the diametrical expansion pressing member presses the rear end portion of the protector to the collar side. At this time, since the protector is expanded by the pressure of air and the protector holding member slidably holds the protector, the movement of the protector with respect to the collar is comparatively smooth. Therefore, the protector is attached to the collar in the expanded state, and labor is not required. Further, if the protector is positioned with respect to the collar, the relative position with respect to the collar will not be displaced, and the front end portion of the protector will be accurately attached to the collar.
