PROBLEM TO BE SOLVED: To reduce weight and cost, without impairing the original function.SOLUTION: A door roller comprises a support member 130 for rotatably supporting a wheel 331 via an axle 330 and a base member 230 for rotatably supporting a base end part of the support member 130 via a support shaft 350 along the axle 330, and a screw member 340 and a torsion spring 351 for regulating a rotation attitude of the support member 130 to the base member 230 are provided between the support member 130 and the base member 230, and the base member 230 comprises a guide member 233 for regulating a rotational upper limit position of the support member 130 to the base member 230 and limiting the separation-movement of the support member 130 to the base member 230 by engaging with a tip part of the support member 130 and a stopper member 234 provided in a different position from the guide member 233 and regulating a rotational lower limit position of the support member 130 to the base member 230 by abutting on the support member 130.SELECTED DRAWING: Figure 3
【課題】本来的な機能を損なうことなく、軽量化及びコストの低減を図ること。【解決手段】車軸３３０を介して車輪３３１を回転可能に支持する支持部材１３０と、車軸３３０に沿った支持軸３５０を介して支持部材１３０の基端部を回転可能に支持するベース部材２３０とを備え、支持部材１３０とベース部材２３０との間には、ベース部材２３０に対する支持部材１３０の回転姿勢を規定するネジ部材３４０及びねじりバネ３５１が設けてあり、ベース部材２３０は、支持部材１３０の先端部に係合することにより、ベース部材２３０に対する支持部材１３０の回転上限位置を規定するとともに、ベース部材２３０に対する支持部材１３０の離隔移動を制限するガイド部材２３３と、ガイド部材２３３とは異なる位置に設けてあり、支持部材１３０に当接することによりベース部材２３０に対する支持部材１３０の回転下限位置を規定するストッパ部材２３４とを備えた。【選択図】図３
