摘要： An engine-driven blower unit has a casing, an impeller provided inside the casing, and an engine. The casing has a first opening on its wall close to the cooling fan of the engine so that a portion of the air inside the casing is let out through the first opening toward the engine. A second opening is formed so that a portion of the air around the engine is lead to the inside of the casing, to the downstream of the first opening. Thereby, engine-cooling effect is improved, and operational noise is reduced.

摘要： A hand lever device is adapted so that a throttle valve as a driven member can be adjusted appropriately in its degree of opening via a cable and kept at a desired degree of opening and yet immediately returned to the minimum degree of opening. The throttle valve can be brought to the degree of opening at which it had stood before it was returned to the minimum opening degree without the necessity of readjustment. The hand lever device comprises a main lever (30) and a sub-lever (60) which ice pivotally operated, wherein the sub-lever (60) is adapted to draw a cable (20) connected to a driven member (CV) via a pulley (50), and wherein the pulley (50) is moved by the main lever (30).
