To provide a rolling resistance measurement device that reduces a change in mechanical resistance to quickly make the mechanical resistance stationary in rolling resistance measurement.SOLUTION: A rolling resistance measurement device 10 includes a load wheel 80 that is rotationally supported by a support shaft 44 extending in a vertical direction via an upper side load wheel bearing 78U and a lower side load wheel bearing 78D, and has an outer peripheral surface 82S in contact with a tread surface of a tire T rotationally driven along a shaft line A in parallel with a support shaft 44, a load cell 54 that measures a load applied to the support shaft 44, a support unit 60 that drops and supplies a lubricant L to the upper side load wheel bearing 78U and the lower side load wheel bearing 78D from above in the vertical direction, and a heating unit 70 that heats the upper side load wheel bearing 78U and the lower side load wheel bearing 78D.SELECTED DRAWING: Figure 2
【課題】本発明は、転がり抵抗測定における機械的抵抗の変化を低減し、機械的抵抗の早期定常化を図られる転がり抵抗測定装置の提供を目的とする。【解決手段】鉛直方向に延びる支持軸44に上側ロードホイール軸受78U及び下側ロードホイール軸受78Dを介して回転可能に支持され、支持軸44と平行する軸線Aに沿って回転駆動されるタイヤTのトレッド面に接触する外周面82Sを有するロードホイール80と、支持軸44に加わる荷重を測定するロードセル54と、鉛直方向の上方から上側ロードホイール軸受78U及び下側ロードホイール軸受78Dに潤滑液Lを滴下して供給する供給部60と、上側ロードホイール軸受78U及び下側ロードホイール軸受78Dを加熱する加熱部70と、を備える、転がり抵抗測定装置10。【選択図】図2
