## Abstract

For mounting on a wheel nut or similar a rotation indicator device includes a body of one piece construction having an annular portion to releasably fit in non-rotatable manner onto the nut and having an end wall portion provided with an indicator. The indicator is provided within the periphery of the device, at a position which, in use, overlies the nut to which it is fitted, by having at least one opening in the end wall portion with free edges configured as the indicator (e.g. pointer with tip). The one piece device may also include side walling of part annular configuration extending between the annular portion and the end wall portion with the free edges being where the side walling is not connected to the end portion. A support post may then extend between the annular portion and the end wall portion at a location remote from the side walling.

## Claims

### Claim at position 1

1-11. (canceled)

### Claim 12

A rotation indicator device comprising:
an annular portion;
an end wall portion; and
a side wall of part-annular configuration extending between part of said annular portion and said end wall portion;
wherein said end wall portion has a free edge where said end wall portion is not connected to said side wall; and
wherein said free edge defines an indicator.

### Claim 13 (depends on 12)

A device according to claim 12 wherein the free edge comprises converging oblique portions.

### Claim 14 (depends on 12)

A device according to claim 12, wherein the side wall extends substantially halfway around the body.

### Claim 15 (depends on 13)

A device according to claim 13, further comprising:
a support post extending between the annular portion and the end wall portion at a location remote from the side wall.

### Claim 16 (depends on 15)

A device according to claim 15,
wherein ends of each of the converging oblique portions define a tip; and
wherein the support post is located to support the tip.

### Claim 17 (depends on 12)

A device according to claim 12,
wherein a liftable tab is integrally formed in the end wall portion.

### Claim 18 (depends on 17)

A device according to claim 17, wherein the tab is hingedly connected to the end wall portion.

### Claim 19 (depends on 12)

A device according to claim 12, wherein the annular portion comprises spaced internal grooves.

### Claim 20 (depends on 12)

A device according to claim 12, wherein the device is of one piece construction.

### Claim 21 (depends on 12)

A device according to claim 12, wherein said annular portion is configured to enable the device to be releasably fitted in a non-rotatable manner onto a nut or onto a head of a bolt.

### Claim 22 (depends on 21)

A device according to claim 21, wherein, in use, said indicator is at a position overlying the nut or head of the bolt.

### Claim 23 (depends on 19)

A device according to claim 19, wherein said internal grooves enable the device to be fitted in a non-rotatable manner onto a nut or onto the head of a bolt in any one of a plurality of selected positions.
