## Abstract

A fueling apparatus 1 including: a fueling pipe 4 accommodated in a housing main body 2 having a fueling mechanism, one end of the fueling pipe 4 being connected to the fueling mechanism; an elbow 5 connected to another end of the fueling pipe 4; a fueling hose 10, one end of which being connected to a fueling nozzle 11 with vapor recovering function, and in which a vapor passage 10c and a fuel oil passage 10d are separately disposed from each other; and a separable joint 9 for communicating the fuel oil passage 10d of the fueling hose 10 and inside of the elbow 5 with each other, and for communicating the vapor passage 10c of the fueling hose 10 and a vapor pipe 4 connected to the vapor recovery mechanism with each other.

## Claims

### Claim 1

A fueling apparatus comprising:
a fueling pipe accommodated in a housing main body having a fueling mechanism, one end of the fueling pipe being connected to the fueling mechanism;
an elbow connected to another end of the fueling pipe;
a fueling hose, one end of which being connected to a fueling nozzle with vapor recovering function, and in which a vapor passage and a fuel oil passage are separately disposed from each other; and
a separable joint for communicating the fuel oil passage of the fueling hose and inside of the elbow with each other, and for communicating the vapor passage of the fueling hose and a vapor pipe connected to the vapor recovery mechanism with each other.

### Claim 2 (depends on 1)

The fueling apparatus as claimed in claim 1, wherein a safety pipe joint is mounted between the fuel oil passage of the fueling hose and the elbow.

### Claim 3 (depends on 2)

The fueling apparatus as claimed in claim 2, wherein the vapor pipe connected to the vapor passage of the separable joint has a notch for breaking the vapor pipe when the safety pipe joint releases connection between the elbow and the separable joint.

### Claim 4 (depends on 2)

The fueling apparatus as claimed in claim 2, wherein the vapor pipe connected to the vapor passage of the separable joint has a connecting portion for dividing the vapor pipe into two parts when the safety pipe joint releases connection between the elbow and the separable joint.
