Abstract
An opening/closing valve structure for an engine is provided with a valve body for opening and closing an intake passage or an exhaust passage of the engine; a pair of bush members mounted on axial ends of the valve body; and a shaft member axially passing through one of the bush members and projecting from the bush member by a predetermined length within one end of the valve body. Each of the bush members is mounted in such a manner that a part of the bush member is axially received in an end of the valve body and the remaining part thereof axially projects from the end of the valve body. A portion of the shaft member projecting from the one of the bush members is connected to the valve body in such a manner that relative rotation of the shaft member with respect to the valve body is disabled.
