The invention is to provide a sprocket holder that can reduce a volume when being removed from a multi-stage rear sprocket assembly. A sprocket holder (55) is used in a multi-stage rear sprocket assembly (27). The multi-stage rear sprocket assembly (27) includes a plurality of connecting sprockets (31) and at least one separation sprocket (33). The sprocket holder (55) includes a base body (61). The base body (61) is configured to deform between a flat state and an engaged state. In the flat state, the base body (61) is flat. In the engaged state, the base body (61) is allowed to deform toward the multi-stage rear sprocket assembly (27) at least along an axial direction with respect to a center axis (X) of a rotation center when the sprocket holder (55) is engaged with the multi-stage rear sprocket assembly (27).
