## Abstract

A knuckle guard of the embodiment includes a guard member disposed in front of a grip of a handle of a vehicle, a connecting member connected to the guard member, and a detachment structure provided in an attachment part between the guard member and the connecting member and configured to detach the guard member forward from the connecting member when a load exceeding a set value is applied to the guard member from behind, in which the detachment structure is provided in an inner portion in a vehicle width direction of the guard member.

## Claims

### Claim 1

A knuckle guard comprising:
a guard member disposed in front of a grip of a handle of a straddle-type vehicle;
a connecting member connected to the guard member; and
a detachment structure provided in between the guard member and the connecting member and detaches the guard member forward from the connecting member when a load exceeding a set value is applied to the guard member from behind, wherein
the detachment structure is provided in an inner portion in a vehicle width direction of the guard member, wherein
the detachment structure includes:
an elastic protruding part which protrudes rearward from the guard member and is elastically deformable;
a protruding part holding hole provided in the connecting member for attachment of the elastic protruding part; and
a protruding part detaching hole continuous with the protruding part holding hole for detachment of the elastic protruding part, and
the protruding part holding hole is provided on a rearward side of the protruding part detaching hole, wherein
the protruding part detaching hole is arranged on an outside of the protruding part holding hole in the vehicle width direction.

### Claim 2 (depends on 1)

The knuckle guard according to claim 1, wherein
the connecting member includes an attachment surface inclined inward in the vehicle width direction and rearward with respect to a front of the vehicle when viewed from above,
the protruding part holding hole and the protruding part detaching hole are provided on the attachment surface, and
the elastic protruding part is held by the protruding part holding hole from a front of the attachment surface.

### Claim 3 (depends on 1)

The knuckle guard according to claim 1, wherein
the protruding part holding hole and the protruding part detaching hole have a continuous shape,
the protruding part detaching hole is larger than the protruding part holding hole, and
the protruding part holding hole is continuous with the protruding part detaching hole via a narrow-constricted part which is smaller than the protruding part holding hole.

### Claim 4 (depends on 1)

The knuckle guard according to claims 1, wherein the detachment structure further includes a fastening member which fastens together the guard member and the connecting member by elastically deforming the elastic protruding part.
