Abstract

A door opening and closing apparatus including a lock mechanism that is configured to hold the door in a fully closed state, and that has an engaging member which engages with a lock member provided in the door when in the fully closed state. A link mechanism having a plurality of link members is configured to be able to undergo deformation into a linear state and a bent state, and restricts rotation of the engaging member by being brought into the linear state. In the link mechanism, a first face is pressed by a projecting shaft moved by the actuator in order that the link mechanism changes from the linear state to the bent state, and a second face is pressed by the projecting shaft in order that the link mechanism changes from the bent state to the linear state.
