Abstract
PURPOSE: To reduce rotational noise and production cost of a fan by manufacturing a blade piece of metal and a ring frame and side plate of synthetic resin.
CONSTITUTION: To withstand a high wind pressure a blade piece 2 is made of metal and a ring frame 5 and side plate 7 are made of sunthetic resin such as plastics. Thus, vibration noise is absorbed by the ring frame 5 and side plate 7 of synthetic resin so that the rotational noise and production cost of a fan can be reduced.
