An example of a charging apparatus includes a housing, a first movable member, and a second movable member. The first movable member is configured to be pressed down. The second movable member accommodates a charging terminal in the housing in a reference state, and when the first movable member has been pressed down, causes the charging terminal to protrude through an opening portion provided in the housing, so as to enter a terminal contact state. The first movable member and the second movable member are configured such that an amount of movement of the charging terminal during a period from the reference state to a predetermined intermediate state is smaller than the amount of movement during the same period in a case where the charging terminal moves from the reference state to the terminal contact state by an amount proportional to an amount of pressing down the first movable member.
