Abstract

PROBLEM TO BE SOLVED: To provide outdoor equipment which has reinforced a large-sized disk area of a fan ring and more reinforced with a load exerted from the upper part of a synthetic resin made outer shell. SOLUTION: The load exerted from above on the top of a front cover 8 is received with the top of a fan ring 7 and its horizontal extension area 7d by way of a first reinforcing rib 7a provided on the top of the fan ring 7. The same load is received with a projection 2a of a base plate 2 by way of a second reinforcing rib 7b provided on the lower part of the fan ring 7 while the load received with the upper part of the fan ring 7 and the horizontal extension area 7d is received with a fan motor mounting mount 62 by way of a support portion 62a which projects toward the upper part of the fan motor mounting mount 62. The same load is so arranged that it may be received with the base plate 2, thereby defusing the load which is exerted to a large-sized disk shaped- space in the central part of the fan ring 7 whose strength is weak.
