An object of the present invention is to provide a valve mechanism for suppressing violent displacement of a valve in a direction of crossing a stroke axis when a valve is opened and closed, and a high-pressure fuel supply pump including the same. The valve mechanism of the present invention includes a seat member having a seat surface, and a valve for contacting the seat surface. The valve mechanism includes a valve housing for accommodating the seat member and the valve, and the valve housing is formed in a shape of restricting displacement of the valve in a crossing direction crossing an opening and closing direction of the valve.
