## Abstract

At a present buckle device, lateral slits are formed in lateral portions of a slider of a buckle switch. A tab is formed at a portion, which is further toward a device upper side than the lateral slit, of a lateral portion that is at a device left side. A portion, which is further toward a device lower side than the lateral slit, at the lateral portion is an elastic portion, and a magnet is held thereat. Therefore, even if the tab receives pushing force from an ejector and is deformed, deformation arising at the elastic portion can be suppressed, and holding of the magnet can be stabilized.

## Claims

### Claim 1

A buckle device comprising:
a buckle main body configured such that a tongue provided at a webbing of a seatbelt device is inserted into an inner side of the buckle main body and is held at a predetermined position at the inner side of the buckle main body; and
a moving body detecting unit that has a moving body that can move due to movement of the tongue inserted into the buckle main body, the moving body detecting unit detecting whether or not the tongue is inserted to the predetermined position in the buckle main body on the basis of a result of detection of the moving body;
wherein the moving body detecting unit includes a holding unit which is movable with respect to the buckle main body, the holding unit including
a holding portion at which the moving body is held, and
a pressure receiving portion that is pushed directly or indirectly by the tongue inserted into the buckle main body,
the holding portion and the pressure receiving portion being formed at the holding unit, and
wherein the holding unit, the holding portion, and the pressure receiving portion move with respect to the buckle main body, together with the moving body which is held at the holding portion, due to the pressure receiving portion being pushed, and
wherein the pressure receiving portion and the holding portion are separated such that deformation of the holding portion due to the pushing force applied directly or indirectly to the pressure receiving portion is suppressed.

### Claim 2 (depends on 1)

The buckle device of claim 1, wherein a limiting portion is provided at the holding portion to face the moving body, the limiting portion limiting movement of the moving body toward an outer side of the holding portion.

### Claim 3 (depends on 2)

The buckle device of claim 2, wherein a slit is provided between a pressure receiving portion disposed location at which the pressure receiving portion is disposed at the holding unit and a holding portion disposed location at which the holding portion is disposed at the holding unit.

### Claim 4 (depends on 3)

The buckle device of claim 3, wherein the moving body detecting unit is provided with a housing at whose inner side the holding unit is disposed, and that has a portion facing the pressure receiving portion disposed location and the holding portion disposed location at the holding unit in a state in which the holding unit is disposed at the inner side of the housing.

### Claim 5 (depends on 1)

The buckle device of claim 1, wherein a slit is provided between a pressure receiving portion disposed location at which the pressure receiving portion is disposed at the holding unit and a holding portion disposed location at which the holding portion is disposed at the holding unit.

### Claim 6 (depends on 5)

The buckle device of claim 5, wherein the moving body detecting unit is provided with a housing at whose inner side the holding unit is disposed, and that has a portion facing the pressure receiving portion disposed location and the holding portion disposed location at the holding unit in a state in which the holding unit is disposed at the inner side of the housing.

### Claim 7 (depends on 1)

The buckle device of claim 1, wherein the holding unit slide-moves with respect to the buckle main body due to the pressure receiving portion being pushed.

### Claim 8 (depends on 1)

The buckle device of claim 1, wherein the holding portion and the pressure receiving portion formed as one piece with the holding unit, but are spaced apart from one another.
