To provide wheel structure in which a cooling capability in the periphery of an in-wheel motor can be improved.SOLUTION: Wheel structure 1 comprises: a wheel in which a groove section 112a extending in a radial direction is formed; a wheel cover 12 which can rotate around a shaft of a rotary shaft O with respect to the wheel and in which a groove section 12a extending in the radial direction is formed in a surface opposing to the groove section 112a; a weight member 15 having a body section to be stored in the groove section 112a and a pin section to be stored in the groove sections 12a; and an elastic member which energizes the weight members 15 toward the rotary shaft O. The wheel cover 12 has a plurality of openings A. When rotation speed of a wheel is above predetermined speed, the weight member 15 is moved along the groove section 112a and groove section 12a to outside in a radial direction by centrifugal force, and with the movement of the weight member 15, the wheel cover 12 is rotated in a circumferential direction with respect to the wheel, so that a portion other than the opening A of the wheel cover 12 covers the wheel and the area of the opening A is increased.SELECTED DRAWING: Figure 1
【課題】インホイールモータ周辺の冷却能力を向上させることができるホイール構造を提供すること。【解決手段】ホイール構造1は、径方向に延びる溝部112aが形成されたホイールと、ホイールに対して回転軸Oの軸まわりに回転可能であり、溝部112aと対向する面に径方向に延びる溝部12aが形成されたホイールカバー12と、溝部112aに収容される本体部および溝部12aに収容されるピン部を有する重り部材15と、重り部材15を回転軸Oに向かって付勢する弾性部材と、を備え、ホイールカバー12が、複数の開口部Aを有し、車輪の回転数が所定以上の場合、遠心力によって重り部材15が溝部112aおよび溝部12aに沿って径方向外側に移動し、それに伴いホイールカバー12がホイールに対して周方向に回転することにより、ホイールカバー12の開口部A以外の部分がホイールを覆い、開口部Aの面積が拡大する。【選択図】図1
