プに寄与する効果が期待できる。 The propeller shaft 1 having the above configuration has the following effects. That is, according to the above configuration of the present invention, the propeller shaft 1 having the spiral blades 3 and housed in the casing 5 has a mechanical function that is not limited to the original function of transmitting rotation of the engine to the rear wheels. Since it constitutes a conveyor or turbine mechanism, etc., the introduction hole 7 and the engine exhaust part are directly connected, exhaust gas is introduced into the casing 5, and the exhaust gas is circulated through the casing 5 and discharged from the exhaust hole 8. The rotation of the spiral blade 3 is promoted by the exhaust impact of the gas, or the gas suction effect accompanying the rotation of the propeller shaft 1 reduces the exhaust resistance of the engine, resulting in energy savings and engine power. Various effects can be expected from the application. For example, when the car is in low gear when starting, the engine is rotating at high speed and the propeller shaft is rotating at low speed, the exhaust energy of the exhaust gas acts on the spiral blade 3 and contributes to promoting the rotation of the propeller shaft 1, thereby saving energy. You can expect good results. Furthermore, when the circumferential speed of the helical blade 3 exceeds the exhaust speed of the exhaust gas during high-speed running, a differential pressure is generated inside the casing 5 due to the gas discharge action based on the rotation of the helical blade 3, and the exhaust gas is Since the gas exhaust resistance is alleviated and eliminated, it can be expected to contribute to increasing the power of the engine.
