## Abstract

A linear sensor apparatus for a vehicle includes a housing which includes an accommodation space therein, a mobile member which is provided in the accommodation space and has at least a part that extends from the housing outward to be connected to a predetermined driving system of the vehicle and linearly moves between a first area and a second area according to driving of the driving system, a magnet member provided in the mobile member, and an output unit which outputs an OFF value when the magnet member is located in the first area and outputs an ON value when the magnet member is located in the second area.

## Claims

### Claim 1

A linear sensor apparatus for a vehicle, comprising:
a housing which comprises an accommodation space therein and has an upper housing and a lower housing;
a mobile member which is provided in the accommodation space and extends from the housing outward, and linearly moves between a first area and a second area;
a magnet member provided in the mobile member; and
an output unit which outputs an OFF value when the magnet member is located in the first area and outputs an ON value when the magnet member is located in the second area,
wherein the lower housing includes a through hole formed in a longitudinal direction of the housing so that the mobile member moves along the through hole in the longitudinal direction, and
wherein the mobile member comprises:
an accommodation portion provided in the accommodation space, in which the magnet member is provided; and
an extending portion which is connected to the accommodation portion and extends from the accommodation space outward toward the through hole so that the extending portion passes through the through hole.

### Claim 2 (depends on 1)

The linear sensor apparatus of claim 1, wherein the accommodation portion comprises an accommodation groove having a shape corresponding to the magnet member, into which the magnet member is mounted.

### Claim 3 (depends on 1)

The linear sensor apparatus of claim 1, wherein a width of the accommodation portion is greater than a width of the through hole, and wherein a width of the extending portion is smaller than the through hole.

### Claim 4 (depends on 1)

The linear sensor apparatus of claim 1, wherein the magnet member comprises protruding portions which protrude from both sides of the mobile member, and
wherein the housing comprises switch units which are in contact with the protruding portions and generate an electrical signal while the magnet member is located in the second area and transmit the electrical signal to the output unit.

### Claim 5 (depends on 4)

The linear sensor apparatus of claim 4, wherein the switch units are formed to be long in a longitudinal direction of the second area.

### Claim 6

A linear sensor apparatus for a vehicle, comprising:
a housing which comprises an accommodation space therein and has an upper housing and a lower housing;
a mobile member which is provided in the accommodation space and extends from the housing outward, and linearly moves;
a magnet member provided in the mobile member; and
an output unit which outputs a value corresponding to a position of the magnet member;
wherein the lower housing includes a through hole formed in a longitudinal direction of the housing so that the mobile member moves along the through hole in the longitudinal direction, and
wherein the mobile member comprises:
an accommodation portion provided in the accommodation space, in which the magnet member is provided; and
an extending portion which is connected to the accommodation portion and extends from the accommodation space outward toward the through hole so that the extending portion passes through the through hole.
