Claims

[Scope of Claim for Utility Model Registration] A poppet valve that opens and closes an intake port communicating with a combustion chamber, and a rotary valve that is located upstream of the poppet valve in the intake direction and is rotatable to open and close the intake passage. and a phase having a structure in which the support shaft of the rotary valve is used as an output shaft, and the crank rotational force of the engine is transmitted to the output shaft as an input, and the rotational phase of the output shaft is changed with respect to the crank rotational phase. An intake control structure for an automobile engine comprising a variable mechanism and a drive unit that changes the rotational phase of the output shaft in the phase variable mechanism, wherein the phase variable mechanism is integrated with a pulley to which the crank rotation is transmitted. The planetary gear mechanism includes a sun gear, a planetary gear meshing with the sun gear, and a ring gear meshing the planetary gear with internal teeth. The ring gear is rotatably supported, and an output gear integrated with the support shaft of the rotary valve is meshed with external teeth formed on the outer periphery of the ring gear.
An oil passage opened along the axial direction and a sub-oil passage passing through the oil passage radially along the radial direction are formed, and the lubricating oil that passes through the bearing surface via the sub-oil passage falls. In the gear box storing each of the gears, there is a cavity that can be flipped up by the rotation of the output gear and stores lubricating oil in an amount that can come into contact with a part of the circumferential surface of the planetary gear. A lubrication structure for an intake system, characterized in that a lubrication section for each of the gears is configured by providing an oil reservoir formed by:
