Abstract:
The present invention provides a sealing member and an air intake controller. A sealing member  1  includes an inner cylindrical section  3  having a gradually-decreasing-diameter portion  2  which has a diameter that gradually decreases in one direction, an outer cylindrical section  5  having a gradually-increasing-diameter portion  4  which has a diameter that gradually increases in the one direction, and an annular connecting section  6  which connects the inner cylindrical section  3  and the outer cylindrical section  5  at an end portion on the side in the opposite direction from the one direction. The outer cylindrical section  5  has an extended cylindrical portion  7,  the outer diameter of which gradually decreases in the one direction. An air intake controller  11  has the sealing member  1  between a shaft hole  15 a  and a valve shaft  8 a.

Claim (Index 3):
An air intake controller that controls the air intake of an internal combustion engine, comprising:\n a main body having an intake passage formed therein; a throttle valve for opening/closing the intake passage; a valve shaft which is rotatably supported by two shaft holes provided in the main body and to which the throttle valve is fixed; and the sealing member which is installed in a sealing groove provided in an outer periphery of the valve shaft and airtightly seals a gap between the shaft hole and the valve shaft, wherein the sealing member includes:\n an inner cylindrical section having a gradually-decreasing-diameter portion which has a diameter that gradually decreases in one direction; \n an outer cylindrical section having a gradually-increasing-diameter portion which has a diameter that gradually increases in the one direction; and \n an annular connecting section which interconnects the inner cylindrical section and the outer cylindrical section at end portions thereof on an opposite direction side from the one direction, \n the outer cylindrical section includes an extended cylindrical portion which extends in the one direction from an end of the gradually-increasing-diameter portion on the one direction side, and an outer diameter of the extended cylindrical portion gradually decreases in the one direction.
