## Abstract

A nut member, which is used for an aiming mechanism of a lamp configured by an aiming screw 120 that is supported in a lamp body 101 so as to turn on its own axis and a nut member 1 that is supported in a bracket 109 of a reflector, includes a fitting portion 3 which is to be fitted in a fitting hole 110 provided in the bracket 109, and an internal thread portion 2 which is to be screwed on to an external thread portion 121 of the aiming screw 120, and an introducing portion 4 which guides the aiming screw 120, wherein the fitting portion 3 and the internal thread portion 2 are formed in different axial positions on the nut member 1.

## Claims

### Claim 1

A nut member comprising:
a fitting portion which is to be fitted in a fitting hole provided in a target member; and
an internal thread portion which is to be screwed on to an external thread portion of a screw by an insertion of the screw,
wherein the fitting portion and the internal thread portion are formed in different axial positions on the nut member.

### Claim 2 (depends on 1)

The nut member according to claim 1, wherein the fitting portion has a fitting groove that fits in the fitting hole, and a cavity is provided on an inner side of a groove bottom surface of the fitting groove.

### Claim 3 (depends on 1)

The nut member according to claim 1, wherein an introducing portion having an inverse cone surface is provided at an end portion of the internal thread portion from which the screw is inserted to guide a distal end of the screw.

### Claim 4 (depends on 1)

The nut member according to claim 1, wherein the screw is an aiming screw that is supported on a fixed member of a lamp so as to turn on its own axis, and the nut member is an aiming nut that is supported on a tilting member such as a reflector or the like of the lamp.
