## Abstract

This panel (1) has a panel body (10) and a leg (20) that supports the panel body (10). The leg (20) has a shaft (22) that is inserted into the panel body (10), and a leg body (21) to which the shaft (22) is fixed and that is disposed outside of the panel body (10). The leg body (21) is provided with a first rotation stopper (31) that is in direct contact with at least either one of the front face (10A) and the back face (10B) of a panel face of the panel body (10) and that stops rotation of the panel body (10) in one direction around the shaft (22), and a second rotation stopper (32) that is configured to stop the rotation of the panel body (10) in the direction opposite to the one direction.

## Claims

### Claim 1

A panel comprising:
a panel body; and
a leg which supports the panel body,
wherein the leg includes:
a shaft inserted into the panel body; and
a leg body to which the shaft is fixed and which is disposed outside the panel body, and
the leg body is provided with:
a first rotation stopper which is configured to come into contact with either one of opposing panel surfaces of the panel body and stop rotation of the panel body in one direction around the shaft; and
a second rotation stopper which is configured to come into contact with either one of the opposing panel surfaces of the panel body and stop rotation of the panel body in a direction opposite to the one direction.

### Claim 2 (depends on 1)

The panel according to claim 1, wherein the first rotation stopper and the second rotation stopper are configured to come into contact with a peripheral edge of the panel body.

### Claim 3 (depends on 2)

The panel according to claim 2, wherein the first rotation stopper and the second rotation stopper extend substantially parallel to opposing surfaces of the peripheral edge and are connected to each other at a connection portion substantially parallel to an end surface of the peripheral edge.

### Claim 4 (depends on 3)

The panel according to claim 3, wherein the first rotation stopper and the second rotation stopper stand upward in a same direction from the connection portion and form an engagement recess having the connection portion as a bottom surface.

### Claim 5 (depends on 4)

The panel according to claim 4 further comprising:
a recess-shaped cover which covers the peripheral edge of the panel body; and
a connecting portion which connects the cover to the engagement recess.

### Claim 6 (depends on 1)

The panel according to claim 1,
wherein the leg is each one of a pair of legs that are provided with an interval therebetween in a width direction of the panel body, and
the first rotation stopper and the second rotation stopper of each one of the pair of legs extend in directions to face each other.
