摘要： A first part formed of a first material is positioned to a second part formed of a second material, which is different from the first material in degree of modification due to environmental variation, by contacting surfaces of the first and second parts. At least three projections are formed on the contact surface of the first part along a circle whose center is coincident with a reference point. Grooves are formed on the contact surface of the second part so that the respective projections are fitted therein and that have wall surfaces to which the projections can contact at the inner and outer sides of the projections. The width of the grooves is determined so that the projections contact the inner or outer wall surface of the grooves even when the first and second parts deform in different degrees due to environmental variation.

摘要： An impeller of a centrifugal fan having a casing and a multi-blade impeller rotatably supported by a blade holding base in the casing, wherein when the impeller is rotated air is sucked from an air suction port formed on one side wall of the casing, and a centrifugal force is applied on the air, so that air of high pressure is taken out through an outlet formed on a portion of an outer peripheral surface of the casing. An inner peripheral surface of the impeller is formed of a conical surface having a large diameter at the suction port and a small diameter at the blade holding base. The small diameter at the blade holding base is in the range of 70 to 90% of the large diameter at the suction port. The diameter of the inner peripheral surface of the impeller is reduced linearly from a portion at the suction side to a portion at the blade holding base side.
