## Abstract

A liquid ejecting head includes: a first component including a housing portion provided so as to extend in a second direction intersecting a first direction; a second component; a screw that is inserted into a fixing hole extending through the first component and the second component in the first direction and fastens the first component and the second component; and a metal nut that is inserted into the housing portion in the second direction and is coupled to the screw.

## Claims

### Claim 1

A liquid ejecting head comprising:
a first component including a housing portion provided so as to extend in a second direction intersecting a first direction;
a second component;
a screw that is inserted into a fixing hole extending through the first component and the second component in the first direction and fastens the first component and the second component; and
a metal nut that is inserted into the housing portion in the second direction and is coupled to the screw.

### Claim 2 (depends on 1)

The liquid ejecting head according to claim 1, wherein the nut is press-fitted into the housing portion.

### Claim 3 (depends on 1)

The liquid ejecting head according to claim 1, wherein
the housing portion has a first surface that defines an end portion of the housing portion in the second direction, and
a screw hole provided in the nut and the fixing hole are aligned with each other when viewed in the first direction in a state where the nut is in contact with the first surface.

### Claim 4 (depends on 1)

The liquid ejecting head according to claim 1, wherein
the housing portion has a second surface for defining a position in the first direction of the nut housed in the housing portion.

### Claim 5 (depends on 2)

The liquid ejecting head according to claim 2, wherein
the housing portion has a first surface that defines an end portion of the housing portion in the second direction, and
the first surface is provided with an opening communicating with an outside of the housing portion.

### Claim 6 (depends on 2)

The liquid ejecting head according to claim 2, wherein
the nut is provided with a screw groove extending in the second direction.

### Claim 7 (depends on 2)

The liquid ejecting head according to claim 2, wherein
a groove extending in the second direction and communicating with the screw hole of the nut housed in the housing portion is provided in a wall surface of the housing portion.

### Claim 8 (depends on 1)

A liquid ejecting apparatus comprising:
the liquid ejecting head according to claim 1; and
a liquid container that stores liquid to be supplied to the liquid ejecting head.
