Abstract
An intake control valve includes a valve body being made of resin, the valve body configured to be pivotally mounted to a surge tank of an internal combustion engine, the valve body pivoting between an open position and a closed position to for opening and closing a fluid passage formed at a division wall, the division wall dividing inside of the surge tank into two portions; and a bearing being made of metal, the bearing being integrally provided with a first end portion of the valve body by insert molding when resin molding the resin-made valve body.
Claims16
An intake control valve, comprising:
- a valve body being made of resin, the valve body configured to be pivotally mounted to a surge tank of an internal combustion engine, the valve body pivoting between an open position and a closed position to for opening and closing a fluid passage formed at a division wall, the division wall dividing inside of the surge tank into two portions;
- and
- a bearing being made of metal, the bearing being integrally provided with a first end portion of the valve body by insert molding when resin molding the resin-made valve body, wherein
- the bearing is made from a plate-shaped body which is rolled to be formed in a cylindrical shape, the bearing including a pair of facing surfaces facing each other in a circumferential direction;
- and
- the cylindrical bearing including an inner circumferential surface which extends continuously throughout a whole circumference of the bearing in the circumferential direction is formed by a contact of the pair of facing surfaces of the bearing with each other by a molding pressure applied when resin molding the resin-made valve body.
An intake apparatus, comprising:
- a surge tank being provided at an internal combustion engine;
- a valve body being made of resin, the valve body being pivotally mounted to the surge tank of an internal combustion engine, the valve body pivoting between an open position and a closed position to for opening and closing a fluid passage formed at a division wall, the division wall dividing inside of the surge tank into two portions;
- and
- a bearing being made of metal, the bearing being integrally provided with a first end portion of the valve body by insert molding when resin molding the resin-made valve body, wherein
- the bearing is made from a plate-shaped body which is rolled to be formed in a cylindrical shape, the bearing including a pair of facing surfaces facing each other in a circumferential direction;
- and
- the cylindrical bearing including an inner circumferential surface which extends continuously throughout a whole circumference of the bearing in the circumferential direction is formed by a contact of the pair of facing surfaces of the bearing with each other by a molding pressure applied when resin molding the resin-made valve body.
