A wall-mounted housing apparatus includes: a rear case (10); a front cover (20); and a retaining mechanism including a fixed engagement portion (41) and a movable engagement portion (46). The movable engagement portion (46) includes a slidable slide bar (462). The slide bar (462) includes a bar main body (462a) slidable in an apparatus height direction (H), and a portion (462b) to be supported. When the front cover (20) is opened upward at an angle larger than 90°, the slide bar (462) slides down due to its weight, and then, when the front cover (20) is closed at 90°, the portion (462b) to be supported is supported by a support surface (412b) of the fixed engagement portion (41). In such a way, the front cover (20) is retained in a state of being opened at 90°. |
