a plate-shaped gear including a resin and provided at an end of a shaft made of metal driving a valve body, and
a detection target of a non-contact sensor detecting a rotation angle of the shaft provided on the gear,
wherein the gear has a support member made of metal and integrated through insert molding in a state where at least a part of the support member is exposed in one side surface,
the detection target is integrated into the gear along with the support member through the insert molding on a side of the other side surface of the gear,
a shaft unit is configured to an exposure portion of the support member at the gear after the insert molding and the end of the shaft are welded,
the gear has an exposure hole exposing at least a part of the support member on the side of the other side surface of the support member, and
the exposure portion of the support member is abutted on the end of the shaft each other, and a rear side of an abutting part of the support member is irradiated with laser light through the exposure hole from the side of the other side surface of the gear to weld the support member and the shaft.
