To provide a novel lamp fitting.SOLUTION: A sound generation unit 22 includes a sound generation device and an outside housing 30 with which the sound generation device is covered. The outside housing 30 has sound emitting holes 30a through which sound S produced from the sound generation device is emitted and relief holes 30b through which wind entering from the sound emitting holes 30a and heading to the sound generation device escapes to a lateral side. A total area of the relief holes 30b is smaller than a total area of the sound emitting holes 30a.SELECTED DRAWING: Figure 2
