Claims

[Scope of utility model registration request]

An intake control valve is inserted into the intake passage to control the intake air flow path number, and the valve shaft of the intake control valve is rotatably supported by a valve holder fixed to the cylinder head, and the outer periphery of the valve shaft is rotatably supported. is covered with a dust seal member, the upper end of the valve shaft projects upward from the upper end of the valve holder, and a dust cover is attached to the protruding upper end of the valve shaft,
In an intake control device for an internal combustion engine in which an arm is fixed and a tip of the arm is connected to an actuator, a partition wall is provided protruding inside the dust force bar, and a small spacer is provided between the tip of the partition wall and the outer peripheral surface of the valve shaft. An intake air control device characterized in that a gap is formed and a space surrounded by the partition wall, the inner surface on the top side of the dust force bar, and the outer circumferential surface of the valve shaft is used as a grease reservoir chamber.
