気制御構造。[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 variable phase mechanism, wherein the variable phase mechanism is configured to control a pulley to which the crank rotation is transmitted. A planetary gear mechanism comprising an integrated sun gear, a planet gear that meshes with the sun gear, and a ring gear that meshes the planet gear with internal teeth and whose external teeth mesh with the spindle of the rotary valve and an integrated output gear. The worm wheel has a sector gear formed on a part of its circumferential surface, and a throttle sensor for detecting the direction and amount of rotation of the worm wheel is provided on the support shaft of a driven gear that meshes with the sector gear. Among these gears, the gears other than the driven gear are housed in a gear box, and the driven gear and the throttle sensor are housed in a sensor box attached to the gear box. The position where the interference can occur consists of a convex part that protrudes radially from the bearing of the rotating shaft integrated with the pulley and is set at intervals along the rotation locus that correspond to the length of the sector gear. An intake air intake for an automobile engine equipped with a worm wheel position regulating structure, characterized in that a position regulating section is provided, and the axial end of the support shaft of the planetary gear is set to a length that interferes with the position regulating section. Control structure.
