The present invention includes a resin-molded product including at least one magnet having opposite faces extending in directions intersecting with a magnetizing direction of the at least one magnet. The present invention also includes a resin portion molded with the at least one magnet by an insertion molding process, wherein the opposite faces of the at least one magnet are substantially entirely embedded within the resin portion.

Resin-molded products and methods of manufacturing the same

An intake control device for an internal combustion engine having a body member 1 and a throttle valve 5 disposed within an air passage 4 . The external circular edge of the throttle valve 5 is divided, with a throttle shaft 6 into a first edge portion 5a which moves toward the upstream side of the air passage 4 and a second edge portion 5b which moves toward the downstream side of the air passage 4. On an inner wall 7 of the air passage 4 of the body member 1 are formed an upstream-side spherical wall surface 8 in a position facing the first edge portion 5a and a downstream-side spherical wall surface 9 in a position facing the second edge portion 5b. A first clearance 13 formed between the first edge portion 5a and the upstream-side spherical wall surface 8 is smaller than a second clearance 14 formed between the second edge portion 5b and the downstream-side spherical wall surface; the second edge portion 5b of the throttle valve 5 may not come into contact with the downstream-side spherical wall surface 9 even when a high intake manifold vacuum is built on the downstream side of the throttle valve 5 when the throttle valve 5 is in a position for closing the air passage 4.
