<p>Inconveniences such as stagnant water around screws, screw corrosion, water invasion into a machine body and outside protrusion of screws are eliminated without lowering work efficiency in screwing and fixing an outdoor machine body to a roof plate. Formed on a roof plate (2) is an outer side surface (2a) which is inclined to an installation surface of the body when the body is to be installed. The outdoor machine body (1) and the roof plate (2) are fixed together at the outer side surface (2a) by means of screws (3), whereby rainwater or the like is made to flow out from the inclined outer side surface (2a) to prevent stagnant water at portions where the screws (3) are fixed.</p> |
