Abstract

The wheel holding member for a vehicle has a rod-like shape, and includes: a thread portion, which is formed on an end portion on a proximal end side, and has a male thread threadedly engageable with a hub bolt hole formed in a wheel hub; a holding portion, which protrudes toward a distal end side with respect to the thread portion, and has no thread on an outer periphery thereof; and a tool insertion hole, which is exposed from an end surface on the proximal end side, and to which a tool for rotating the wheel holding member is insertable. A bottom surface of the tool insertion hole is located on the distal end side with respect to an end of the thread portion on the distal end side.

First claim

What is claimed is:

1. A wheel holding member for a vehicle, which has a rod shape,
and is to be removably mounted to a wheel hub, the wheel holding member being configured to hold a wheel under a state in which the holding member is mounted to the wheel hub, the wheel holding member comprising:
a thread portion, which is formed on one end portion in an axial direction, and has a male thread formed on an outer peripheral surface thereof, the male thread being threadedly engageable with a hub bolt hole formed in the wheel hub; and
a first portion, which extends toward a side opposite to the one end portion of the thread portion, and is insertable through a hub-bolt insertion hole formed in the wheel,
wherein at least the thread portion has a tool insertion hole, which is opened at an end surface of the one end portion, and into which a tool for rotating the wheel holding member is insertable, and
wherein the tool insertion hole is formed such that a bottom surface of the tool insertion hole is located on an outer side in a vehicle width direction with respect to a surface of the wheel hub in which the hub bolt hole is formed under a state in which the thread portion is threadedly engaged with the hub bolt hole.

2. The wheel holding member for a vehicle according to claim 1 , wherein the bottom surface of the tool insertion hole is located on the side opposite to the one end portion with respect to a boundary between the thread portion and the first portion.

3. The wheel holding member for a vehicle according to claim 1 , wherein the first portion has a portion having an outer diameter larger than an outer diameter of the thread portion.

4. The wheel holding member for a vehicle according to claim 1 , further comprising a second portion, which is formed on the side opposite to the one end portion with respect to the first portion, and has a non-circular shape in cross section taken along a plane orthogonal to the axial direction.

5. The wheel holding member for a vehicle according to claim 4 , wherein the second portion has a substantially “I” shape in cross section.

6. The wheel holding member for a vehicle according to claim 4 , wherein the second portion has a tapered shape that becomes thinner toward an end portion on the side opposite to the one end portion.

7. The wheel holding member for a vehicle according to claim 1 , further comprising a tool portion, which is formed on the end portion on the side opposite to the one end portion, is insertable into the tool insertion hole, and is capable of rotating the wheel holding member under a state in which the tool portion is inserted into the tool insertion hole.

8. The wheel holding member for a vehicle according to claim 7 ,
wherein the tool insertion hole is a hole having a hexagonal cross section, and
wherein the tool portion is a rod-shaped portion having a hexagonal cross section.
