AIRFLOW CONTROL VALVE STRUCTURE
First Claim
1. An airflow control valve structure comprising:
- a metal connecting shaft including an embedded portion, wherein the connecting shaft is configured to rotate about a rotation axis;
a plastic valve body in which the embedded portion is embedded so that the valve body rotates integrally with the connecting shaft, wherein the valve body is configured to open and close part of a cross-sectional flow area of an intake passage;
a rotation restriction portion located on the embedded portion, wherein the rotation restriction portion restricts rotation of the embedded portion relative to the valve body; and
a movement restriction portion located on the embedded portion, wherein the movement restriction portion restricts movement of the embedded portion relative to the valve body in a direction along the rotation axis.

Abstract
An airflow control valve structure includes a metal connecting shaft and a plastic valve body. The connection shaft includes an embedded portion. The connecting shaft is configured to rotate about a rotation axis. The embedded portion is embedded so that the valve body rotates integrally with the connecting shaft. The airflow control valve structure further includes a rotation restriction portion and a movement restriction portion. The rotation restriction portion is located on the embedded portion and restricts rotation of the embedded portion relative to the valve body. The movement restriction portion is located on the embedded portion and restricts movement of the embedded portion relative to the valve body in a direction along the rotation axis.
