摘要： PROBLEM TO BE SOLVED: To provide a tooth hit noise reducing mechanism for a gear device restricting tooth hit noise caused by backlash. SOLUTION: A drive gear 10 fixed to a crankshaft of an internal combustion engine is engaged with a driven gear 17 fixed to a shaft of a balance shaft. The driven gear 17 is engaged with an oil pump gear 30 to drive an oil pump to feed operating fluid to a hydraulic circuit in the internal combustion engine. By engagement of the driven gear 17 and the oil pump gear 30, rotation resistance is given to the driven gear 17 clockwise in the opposite direction to counterclockwise as a rotation direction of it. A tooth face on the back side of the rotation direction of the driven gear 17 thus gets in contact with a tooth face on the front side of the rotation direction of the drive gear 10. Even when rotation of the drive gear 10 fluctuates, teeth of the drive gear 10 are not hit on teeth of the driven gear 17.

摘要： PROBLEM TO BE SOLVED: To provide a tensioner capable of preferably following a large variation of a vibration mode and realizing a damping thereof by utilizing a fluid pressure by a fluid generally used. SOLUTION: The hydraulic tensioner utilizes a circulation resistance obtained when a viscous oil in a cylinder 3 receiving an insertion pressure flows in a gap of slide surfaces of the cylinder 3 and the plunger 4 when the plunger 4 is inserted into the cylinder 3 filled with the viscous oil. For example, a stepped part is axially provided on the slide surface of the inserted plunger 4 side. A distance of the gap can be varied by whether or not the stepped part is inserted into the cylinder 3 and the circulation resistance of the fluid is varied to change a damping force of the hydraulic tensioner. The hydraulic tensioner is applied to a belt of which a tension vibration mode is varied. A large damping force is generated when the vibration of the belt is large and a small damping force is generated when the vibration of the belt is small. Thereby, a stable action of the belt is obtained without making the tension excessively large.

摘要： PROBLEM TO BE SOLVED: To improve tone quality of an engine with a turbocharger by increasing the level of component of an explosion order in intake noise under acceleration of a vehicle. SOLUTION: One end of a pulsation-takeout duct 51 is connected to an intake manifold 11 (or an exhaust manifold 12) of the engine 1, and the other end thereof is connected to an air-cleaner hose 22 (intake pass) upstream of the turbocharger 4. A valve 52 and a vibration plate 53 are arranged in the pulsation-takeout duct 51. When the vehicle is in a steady driving mode, the valve 52 of the pulsation-takeout duct 51 is closed to keep silence. While on acceleration of the vehicle, the valve 52 is opened to develop vibration in the vibration plate 53 by the pressure pulsation (pulsation including a component of the explosion order) in the exhaust manifold 12. The pressure pulsation is transmitted to the air-cleaner hose 22 to increase the component of explosion order, and on acceleration, a high intake noise is produced. COPYRIGHT: (C)2008,JPO&INPIT
