## Abstract

A stopper device for vehicle includes a movable member, a swing lever capable of swinging in the direction in which the movable member is locked, a solenoid coupled to the swing lever, and a pushing member that pushes the swing lever in the unlocking direction relative to the movable member. The solenoid includes a plunger coupled to the swing lever, and a magnetizing coil to drive the plunger.

## Claims

### Claim 1

A stopper device for vehicle comprising:
a movable member rotatable together with a steering wheel;
a swing lever capable of swinging in a direction in which the movable member is locked;
a solenoid that comprises a plunger coupled to the swing lever and a magnetizing coil to drive the plunger, and that moves the plunger backwardly by magnetization of the magnetizing coil to cause the swing lever to swing in the locking direction;
a first pushing member that pushes the swing lever in n unlocking direction relative to the movable member; and
a second pushing member that pushes the plunger n a forward-movement direction,
wherein, with the magnetizing coil not being magnetized, when either one of the first pushing member or the second pushing member becomes malfunction, the wring lever is capable of swinging in the unlocking direction.

### Claim 2 (depends on 1)

The stopper device for vehicle according claim 1, wherein the magnetizing coil comprises a first coil and a second coil that form a tandem system.

### Claim 3 (depends on 1)

The stopper device for vehicle according to claim 1, further comprising a position detecting unit that detects a slide position of the plunger.

### Claim 4 (depends on 1)

The stopper device for vehicle according to claim 1, wherein the solenoid is a pull-type solenoid that moves the plunger backwardly by magnetization of the magnetizing coil.

### Claim 5 (depends on 1)

The stopper device for vehicle according to claim 1, wherein said stopper device is built in a steering device for vehicle that has a steering unit at which a turning operation of the steering wheel is input and a turning unit that turns turning wheels, the steering unit and the turning unit being mechanically separated from each other,
wherein the swing lever is a component capable of restricting a rotational range of the movable member by being latched with the movable member.

### Claim 6 (depends on 2)

The stopper device for vehicle according to claim 2, further comprising a position detecting unit that detects a slide position of the plunger.

### Claim 7 (depends on 2)

The stopper device for vehicle according to claim 2, wherein the solenoid is a pull-type solenoid that moves the plunger backwardly by magnetization of the magnetizing coil.

### Claim 8 (depends on 2)

The stopper device for vehicle according to claim 2, wherein said stopper device is built in a steering device for vehicle that has a steering unit at which a turning operation of the steering wheel is input and a turning unit that turns turning wheels, the steering unit and the turning unit being mechanically separated from each other,
wherein the swing lever is a component capable of restricting a rotational range of the movable member by being latched with the movable member.

### Claim 9 (depends on 3)

The stopper device for vehicle according to claim 3, wherein the solenoid is a pull-type solenoid that moves the plunger backwardly by magnetization of the magnetizing coil.

### Claim 10 (depends on 3)

The stopper device for vehicle according to claim 3, wherein said stopper device is built in a steering device for vehicle that has a steering unit at which a turning operation of the steering wheel is input and a turning unit that turns turning wheels, the steering unit and the turning unit being mechanically separated from each other,
wherein the swing lever is a component capable of restricting a rotational range of the movable member by being latched with the movable member.

### Claim 11 (depends on 4)

The stopper device for vehicle according to claim 4, wherein said stopper device is built in a steering device for vehicle that has a steering unit at which a turning operation of the steering wheel is input and a turning unit that turns turning wheels, the steering unit and the turning unit being mechanically separated from each other,
wherein the swing lever is a component capable of restricting a rotational range of the movable member by being latched with the movable member.
