  • Patent number: 9863475
    Abstract: A shaft includes a head part having an outer diameter greater than an inner diameter of an inner ring and being in contact with a side surface on one axial end side of the inner ring, and a column part extending from the head part toward the other axial end side and having an axial width greater than a bearing. An external periphery of the other axial end portion of the column part is formed with a male screw to be fastened with a support arm. A side surface on one axial end side of the shaft is formed with a concave section to which a tool capable of rotating the shaft is to be fitted. A bottom part of a housing is formed with a through-hole into which the tool can be inserted, at a position facing the concave section.
