A charging device includes: a connector that protrudes from a placement surface; a protective plate; a wall surface intersecting with the placement surface; a support member capable of moving to be in a first orientation in which the protective plate is supported and a second orientation in which the protective plate is not supported; and a lock mechanism that locks the support member in the first orientation. The lock mechanism includes a first protruding part that, when the support member is locked, releases the locking of the support member by being pushed. The support member (i) includes a second protruding part, and (ii) moves from the first orientation to the second orientation by the second protruding part being pushed toward the wall surface in a state where the locking is released. When the support member has moved, the protective plate is capable of moving to the placement stand.
