Abstract
A locking mechanism for a valve device, which includes a valve body for opening and closing a fluid path, for retaining the valve body at a predetermined opening position, the valve device further including a gear wheel to which rotational driving force of a rotational driving source is transmitted and a rack section having rack teeth provided thereon for meshing engagement with the gear wheel and configured to convert rotational movement of the gear wheel into linear movement and move together with the valve body. The locking mechanism for a valve device includes: a ball abuttable with a wall face of the rack section; and a spring member configured to press the ball toward the wall face; the valve body being retained by frictional force generated when the ball is pressed against the wall face of the rack section.
