DOOR ROLLER
To provide a door roller in which deformation of a shaft member guided by an elongated hole is suppressed.SOLUTION: A door roller includes: cases 51, 52, and 53 provided with shaft support portions which support a wheel 54 for rotation; and a guide member provided with an inclined groove 523 along which a shaft member 6 is guided, the shaft member 6 being configured such that its end portion which abuts on the guide member forming the inclined groove 523 is made up of a pair of parallel surfaces which are in surface contact with the inclined groove 523. The case 53 is formed with a through hole. The shaft member 6 is provided with groove engaging sections engaging with the inclined groove 523 at both ends in the axial direction of the shaft member 6 and an intermediate section 61 between the groove engaging sections. The intermediate section 61 abuts against a portion of the guide member constituting the inclined groove 523.SELECTED DRAWING: Figure 6
【課題】長穴にガイドされる軸部材の変形が抑えられる戸車を提供する。【解決手段】車輪５４を回転可能に支持する軸支持部を備えるケース５１、５２、５３と、軸部材６が案内される傾斜溝５２３が形成された案内部材と、を備え、傾斜溝５２３を形成している案内部材に当接する軸部材６の端部は、傾斜溝５２３に面接触する一対の平行な面からなる戸車である。ケース５３には、貫通孔が形成され、軸部材６は、軸部材６の軸方向における両端部において傾斜溝５２３に係合している溝係合部と、溝係合部の間の中間部６１とを備え、中間部６１は、傾斜溝５２３を構成する案内部材の部分に当接する。【選択図】図６
