## Abstract

An object is to provide a hose joint that is easy to use, without sacrificing workability. A hose joint includes a nipple body and a cap nut. The cap nut has a cylindrical barrel part and a nut part. The nut part has at least one width-across-flats part. A circumscribed circle of an outer periphery of the width-across-flats part has a diameter larger than the diameter of the cylindrical barrel part, and an inscribed circle of the outer periphery of the width-across-flats part has a diameter smaller than the diameter of the cylindrical barrel part.

## Claims

### Claim 1

A hose joint comprising a nipple body and a cap nut, wherein
the cap nut has a cylindrical barrel part and a nut part,
the nut part has at least one width-across-flats part, and
a circumscribed circle of an outer periphery of the one width-across-flats part has a diameter larger than a diameter of the cylindrical barrel part, and an inscribed circle of the outer periphery of the width-across-flats part has a diameter smaller than a diameter of the cylindrical barrel part.

### Claim 2 (depends on 1)

The hose joint according to claim 1, wherein
the nipple body has at least one nipple body width-across-flats part, and
width of the one nipple body width-across-flats part is equal to or larger than the diameter of the cylindrical barrel part of the cap nut.

### Claim 3 (depends on 1)

The hose joint according to claim 1, wherein the width-across-flats part is shaped in a regular polygon width-across-flats part.

### Claim 4 (depends on 3)

The hose joint according to claim 3, wherein the regular polygon width-across-flats part has a chamfered shape.

### Claim 5 (depends on 2)

The hose joint according to claim 2, wherein the width-across-flats part is shaped in a regular polygon width-across-flats part.
