Wheel reaction force detecting apparatus

A wheel reaction force detecting apparatus comprising:

• a mount fixed to a suspension device;
• a hub to which a wheel is fixed, the hub being rotatably supported around an axle of the wheel with respect to the mount;
• a sensing unit including a cylinder, the cylinder being disposed inside the hub and substantially coaxial with the axle, the cylinder having a first end fixed to the mount and a second end connected to the hub with a hub bearing disposed between the cylinder and the hub in a radial direction;
• and
• a component force detector to detect a component force on the wheel, the component force detector being disposed on the cylinder in the sensing unit,
• wherein the hub bearing includes an inner race connected to the sensing unit and an outer race being in contact with the hub, and a position of the outer race is adjustable in an axial direction of the axle with respect to the inner race, and
• wherein the hub includes an annular outer cylinder, the annular outer cylinder comprising:
• an annular step portion in an outer end in the radial direction, the step portion being cut inward in a vehicle width direction and including a threaded portion;
• a receiving recession in an inner end in the radial direction for accommodating the inner race and the outer race of the hub bearing;
• and
• a bearing pushing member attached to the threaded portion of the step portion so as to be movable in the vehicle width direction.
