The invention provides a flywheel assembly for a man-powered vehicle, which can easily stabilize the preload of a bearing unit and can compactly design the axial length. A flywheel assembly (61) is provided with an outer body (63), an inner body (65), a bearing unit (69), and a lock member (71). The lock member (71) suppresses rotation of the inner ring (83) of the bearing unit (69) with respect to the inner body (65). An inner ring threaded portion (83c) of the inner ring (83) is in threaded engagement with an inner body threaded portion (77) of the inner body (65). A lock member threaded portion (71c) of the lock member (71) is in threaded engagement with an inner body threaded portion (77) of the inner body (65). A first tool engagement section (83b) of the inner ring (83) engages with a first tool (87) in the axial direction. A second tool engagement section (71b) of the lock member (71) engages with a second tool (88) in the axial direction.
本发明提供能容易使轴承单元的预压稳定且能紧凑地设计轴向长度的人力驱动车用飞轮组装体。飞轮组装体(61)具备外体(63)、内体(65)、轴承单元(69)和锁定构件(71)。锁定构件(71)抑制轴承单元(69)的内圈(83)相对于内体(65)旋转。内圈(83)的内圈螺纹部(83c)与内体(65)的内体螺纹部(77)螺纹接合。锁定构件(71)的锁定构件螺纹部(71c)与内体(65)的内体螺纹部(77)螺纹接合。内圈(83)的第1工具卡合部(83b)在轴向与第1工具(87)卡合。锁定构件(71)的第2工具卡合部(71b)在轴向与第2工具(88)卡合。
