PROBLEM TO BE SOLVED: To provide a caster which can smoothly pass an irregular part on a road surface or a step part on a road surface and reduce noise or vibration occurring when passing the irregular part on the road surface or the step part on the road surface.SOLUTION: A caster 10 has: a vehicle bearing 12 attached to a movable body 16 and serving as a body part; a wheel 14 rotatably attached to the vehicle bearing 12; and multiple protruding parts 15 protruding from an outer peripheral surface 14a of the wheel 14 in a radial direction of the wheel 14. An elastic modulus of at least a portion P1 of each of the protruding parts 15 which is opposite to a wheel 14 side is lower than an elastic modulus of the wheel 14.SELECTED DRAWING: Figure 2

    【課題】路面の凹凸部又は路面の段差部をスムーズに通過することができ、路面の凹凸部又は路面の段差部を通過する際に発生する騒音又は振動を低減することができるキャスターを提供する。【解決手段】キャスター10は、移動体16に取り付けられる本体部としての車軸受12と、車軸受12に回転可能に取り付けられた車輪14と、車輪14の外周面14aから車輪14の径方向にそれぞれ突出した複数の突出部15と、を有する。複数の突出部15の各々のうち少なくとも車輪14側と反対側の部分P1の弾性率は、車輪14の弾性率よりも低い。【選択図】図2
