Abstract: A electrically driven valve includes a valve main body including a valve chamber, an end opening that communicates with the valve chamber and that is opened in an axial direction, and a side opening that communicates with the valve chamber and that is opened in a direction intersecting the axis, a seat member, at least one portion of which is arranged within the end opening, the seat member including a valve seat disposed on a valve chamber side, a valve element configured to approach to or separate from the valve seat, and a conversion mechanism configured to convert a rotational movement of a rotor into a linear movement of the valve element. The valve main body includes a contact surface configured to restrict a movement of the seat member toward the valve chamber side within the end opening.
