A hinge device has a base, a body removably provided at the base, and a mounting member rotatably connected to the body. The base has a base member, a first movable member disposed at the base member such that the first movable member is movable in a first direction and non-movable in a second direction orthogonal to the first direction, and a second movable member disposed at the first movable member such that the second movable member is movable in the second direction and non-movable in the first direction, and the body removably attached to the second movable member. A first position adjustment mechanism is provided between the base member and the first movable member. The first position adjustment mechanism adjusts position of the first movable member with respect to the base member in the first direction.
