PURPOSE: To prevent a mirror from being hazy and the dew drop of a wall by providing a ventilating fan in a wall above a lighting equipment and covering the front part of the ventilating fan with a partition plate drop from a ceiling.

CONSTITUTION: A ventilating fan 5 is provided at the upper side of a lighting equipment 4 attached to a wall 1. A partition plate 7 is attached to a ceiling 6. This partition plate 7 is drooped from a ceiling 6 spaced by 35cm from the wall 1 to cover the front part of the ventilating fan 5. When the ventilating fan 5 operates, air above a dressing table 2 can be efficiently exhausted by the partition plate 7. As a result, when a hot water supplied from the dressing table 2 is used, a mirror 3 does not become hazy and a steam is not bedewed on the wall, so that a mold is not produced.
