2. Description of the Related Art A hose clip C shown in FIG. 5 is formed by forming a steel plate in an annular shape and forming a knob A composed of a plurality of projecting pieces at an end thereof. As a result, it is elastically deformed so as to expand the diameter. The hose clip C is attached to a position of a predetermined length L from the end of the hose H, and after fitting the hose H to the connection portion J of the structure B as shown in FIG. By re-attaching from the initial position shown by, to a position corresponding to the outer periphery of the connecting portion shown by the solid line in the figure, the hose H functions as a stopper.

If the length L for determining the initial mounting position is too large, the distance becomes useless for the operation of moving the hose clip to the outer periphery of the connecting portion. Since the clip C becomes an obstacle and the hose H cannot be fitted to the connection portion J, it is necessary to accurately manage the hose H.

As an apparatus for attaching a hose clip of this type to a hose, for example, a device for holding a hose clip supplied to a predetermined position in a state where the diameter of the hose clip is expanded and a hose clip inserted through the hose clip are provided. There is a device provided with a guide which is pressed by the guide. The guide is elastically held and is retracted by pushing the hose. Then, the sensor detects that the guide has moved by a predetermined amount, and at this point, by releasing the grip of the hose clip, the hose clip is mounted at a position of a predetermined length from the end of the hose. Yes (Tokuhei 1-
No. 13983).

[0005]

However, in the conventional hose clip mounting device as described above, the hose is pushed in against the elastic body holding the guide, so that the hose is inserted into the hose in the axial direction. A compressive force will be applied, and the mounting position of the hose clip may vary due to the resilience of the elastic body and the elasticity of the hose itself.In addition, if the hand is carelessly released from the hose during the operation, Since there is a possibility that the hose may fly out due to the repulsive force of the elastic body, an improvement capable of coping with these problems has been desired.

Conventionally, since a considerable amount of force is required to fit the hose to the connecting portion after the hose clip is attached, lubricating oil is applied to the end of the hose to lubricate the inner surface and then fit. At this time, it is necessary to prevent lubricating oil from adhering to the outer periphery of the hose so that the hose clip to be remounted and the hose are in good contact with each other. Since it has to be paid, improvement in workability has been desired.

[0007]
