## Abstract

A linear motion mechanism includes a base portion; a guide member attached to the base portion; and a slider provided to slide along an axial direction of the guide member. The guide member is fastened to the base portion by a guide fastening member in a specified fastening direction substantially orthogonal to the axial direction, and is pressed by a guide pressing member in an orthogonal direction substantially orthogonal to both the axial direction and the fastening direction.

## Claims

### Claim 1

A linear motion mechanism, comprising:
a base portion;
a guide member attached to the base portion; and
a slider provided to slide along an axial direction of the guide member,
wherein the guide member is fastened to the base portion by a guide fastening member in a specified fastening direction substantially orthogonal to the axial direction, and is pressed by a guide pressing member in an orthogonal direction substantially orthogonal to both the axial direction and the fastening direction.

### Claim 2 (depends on 1)

The mechanism of claim 1, wherein the slider includes a plurality of members fastened together by a slider fastening member in the fastening direction, the slider being pressed by a slider pressing member in the orthogonal direction.

### Claim 3 (depends on 1)

The mechanism of claim 1, wherein the guide member includes a plurality of members fastened together by the guide fastening member in the fastening direction, the guide member being pressed by the guide pressing member in the orthogonal direction.

### Claim 4 (depends on 2)

The mechanism of claim 2, wherein the guide pressing member and the slider pressing member are configured to press one of the members fastened together by the guide fastening member and the slider fastening member toward a pressed surface formed in the other member.

### Claim 5 (depends on 1)

The mechanism of claim 1, wherein the guide member is provided to extend along a vertical direction.

### Claim 6 (depends on 1)

The mechanism of claim 1, wherein the guide member is provided so extend along a horizontal direction.

### Claim 7 (depends on 1)

The mechanism of claim 1, wherein the base portion is a wall surface.

### Claim 8 (depends on 1)

A robot comprising the linear motion mechanism of claim 1.

### Claim 9 (depends on 8)

The robot of claim 8, further comprising a housing formed into a substantially tubular shape, the guide member including at least one pair of guide members arranged on an inner circumferential surface of the housing serving as the base portion.

### Claim 10 (depends on 9)

The robot of claim 9, wherein the guide member includes two pairs of guide members opposingly arranged on the inner circumferential surface of the housing.
