摘要:
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.

Disclosed herein is a locking mechanism for a valve device having a valve body for retaining the valve body at a predetermined opened position, including: a disk having a rotational shaft rotatable together with a valve body driving shaft and having a cutout groove formed on an outer circumferential face thereof; a ball disposed in the cutout groove; a body member having an axial direction restriction face and an inner circumferential face; a holder member having an engaging face which has a diameter gradually decreasing toward the ball and is engageable with the ball; and a spring member biasing the holder member toward the ball, wherein said ball is clamped by and among the engaging face which is acted upon by the biasing force of said spring member, the axial direction restriction face and the inner circumferential face so that a rotational direction position of the rotational shaft is retained.
