A holding mechanism for a display device has a front cover member attached to a surface of a housing containing the display device so as to cover the display device, and an elastic member arranged between the display device and a front cover member. A thin plate-like member having shape retention is attached to the elastic member on a side facing the front cover member, and the elastic member attached to the thin plate-like member is attached to an internal side of the front cover member to prevent an unsightly appearance and to make the adherence of the elastic member to the surface of the display device easier.
