Provided is a support rod bearing in which a housing is made of synthetic resin, the contact tightness between the housing and a track wheel is improved without increasing the height of the track wheel, and the quality management of the positional relationship between the housing and the track wheel can be improved. The upper rail wheel (4) has an inward flange portion (4A). The lower rail wheel (5) has an outward flange portion (5A). The upper shell (2) has an outward protruding portion (2A) protruding radially outward from a surface facing an end surface (4C) of the inward flange portion (4A) toward the end surface (4C). The lower shell (3) has an inward protruding portion (3A) protruding radially inward from a surface facing an end surface (5C) of the outward flange portion (5A) toward the end surface (5C). The upper side rail wheel (4) is held by the upper side case (2) as the end surface (4C) of the upper side rail wheel (4) is in contact with the outward protruding portion (2A) of the upper side case (2). The lower side rail wheel (5) is held by the lower side case (3) as the end surface (5C) of the lower side rail wheel (5) is in contact with the inward protruding portion (3A) of the lower side case (3).
在将壳做成合成树脂制的支撑杆轴承中,不使轨道轮的高度变高而提高壳与轨道轮的密接性、并且能够提高壳与轨道轮的位置关系的品质管理性的支撑杆轴承。上侧轨道轮(4)具有朝内凸缘部(4A)。下侧轨道轮(5)具有朝外凸缘部(5A)。上侧壳(2)具有从与朝内凸缘部(4A)的端面(4C)对置的面朝向端面(4C)向径向外方突出的朝外凸部(2A)。下侧壳(3)具有从与朝外凸缘部(5A)的端面(5C)对置的面朝向端面(5C)向径向内方突出的朝内凸部(3A)。通过上侧轨道轮(4)的端面(4C)与上侧壳(2)的朝外凸部(2A)接触,上侧轨道轮(4)被上侧壳(2)保持。通过下侧轨道轮(5)的端面(5C)与下侧壳(3)的朝内凸部(3A)接触,下侧轨道轮(5)被下侧壳(3)保持。
