Claims

1. A vehicle wheel driving apparatus arranging structure, comprising: a road wheel;a road wheel supporting member;a suspension member that comprises a plurality of support joints, and connects the road wheel supporting member to a vehicle body to thereby rotatably support the road wheel; anda motor that is connected to the road wheel supporting member and rotates a road wheel side of the road wheel supporting member, whereina center of gravity of the motor is disposed higher than a center of the road wheel, andat least one of the support joints is disposed higher than the center of the road wheel so as to be connected to a motor housing of the motor.

2. The vehicle wheel driving apparatus arranging structure according to claim 1, wherein the support joint disposed higher than the center of the road wheel is disposed above or in the vicinity of a rotational shaft of the motor.

3. The vehicle wheel driving apparatus arranging structure according to claim 1, wherein the support joint disposed higher than the center of the road wheel is mounted on the motor housing via a bracket or directly.

4. The vehicle wheel driving apparatus arranging structure according to claim 1, wherein the support joint is provided on at least one of: an end of an arm disposed so as to be inclined relative to a longitudinal direction of the vehicle body;an end of an arm that holds the road wheel relative to a displacement in a longitudinal direction of the vehicle body; andan end of a suspension constituent member that holds the road wheel relative to the displacement in the longitudinal direction of the vehicle body.

5. The vehicle wheel driving apparatus arranging structure according to claim 1, wherein at least one of the plurality of support joints is disposed lower than the center of the road wheel, and thus disposed support joint is provided on at least one of: an end of an arm disposed so as to be inclined relative to a longitudinal direction of the vehicle body;an end of an arm that holds the road wheel relative to a displacement in a longitudinal direction of the vehicle body; andan end of a suspension constituent member that holds the road wheel relative to the displacement in the longitudinal direction of the vehicle body.
