A human-powered vehicle component includes a housing and a joint provided on the housing and configured to be attached to a support of the human-powered vehicle by a fastener. The joint includes a metal base, a metal coupling portion provided on the base and coupled to the fastener, and an intermediate portion provided between the coupling portion and the base. The base includes a first material having a first standard electrode potential. The coupling portion includes a second material having a second standard electrode potential. The intermediate portion is formed by a third material having a third standard electrode potential or a fourth material having an electric insulating property. A difference of the third and first standard electric potentials and a difference of the third and second standard electrode potentials are each smaller than a difference of the first and second standard electrode potentials.

A separator for sealed cells is provided which attains a high degree of intimate contact with electrode plates, enables the cell to have reduced internal resistance, is less apt to suffer a fatigue phenomenon even upon repetitions of charge/discharge, and improves the life of the cell. Fine rubber particles are adhered to the surface of fibers of a non-woven fabric constituting the separator so that the fine rubber particles are present among the fibers. These fine rubber particles function as elastic bodies to absorb relative positional changes of the fibers and improve the compressive repulsion of the separator.
