A door closing apparatus, comprising: a latching mechanism provided on a vehicle door and configured to be brought into engagement with a striker, which is provided on a vehicle body, to hold the vehicle door in a half closed state and a fully closed state; a closing mechanism configured to be linked with the latching mechanism to shift the latching mechanism from a half latching state where the vehicle door is held in the half closed state to a fully latching state where the vehicle door is held in the fully closed state; and a driving source configured to operate the closing mechanism, wherein the closing mechanism comprises: a driving member configured to be rotated by power of the driving source; a linking member coupled to the driving member relatively rotatably and configured to be translated in response to a rotation of the driving member to be linked with the latching mechanism; and a releasing member configured to rotate in response to an operation of a door opening operation source to release a linkage of the linking member with the latching mechanism, herein the driving member has a shaft portion, which configures a rotational center of the driving member, said driving member being characterized in that the shaft portion of the driving member is supported by the releasing member and in that a state where the shaft portion is supported by the releasing member is cancelled by a rotation of the releasing member in response to an operation of the door opening operation source. a latching mechanism provided on a vehicle door and configured to be brought into engagement with a striker, which is provided on a vehicle body, to hold the vehicle door in a half closed state and a fully closed state; a closing mechanism configured to be linked with the latching mechanism to shift the latching mechanism from a half latching state where the vehicle door is held in the half closed state to a fully latching state where the vehicle door is held in the fully closed state; and a driving source configured to operate the closing mechanism, wherein the closing mechanism comprises: a driving member configured to be rotated by power of the driving source; a linking member coupled to the driving member relatively rotatably and configured to be translated in response to a rotation of the driving member to be linked with the latching mechanism; and a releasing member configured to rotate in response to an operation of a door opening operation source to release a linkage of the linking member with the latching mechanism, herein the driving member has a shaft portion, which configures a rotational center of the driving member, said driving member being characterized in that the shaft portion of the driving member is supported by the releasing member and in that a state where the shaft portion is supported by the releasing member is cancelled by a rotation of the releasing member in response to an operation of the door opening operation source. a driving member configured to be rotated by power of the driving source; a linking member coupled to the driving member relatively rotatably and configured to be translated in response to a rotation of the driving member to be linked with the latching mechanism; and a releasing member configured to rotate in response to an operation of a door opening operation source to release a linkage of the linking member with the latching mechanism, herein the driving member has a shaft portion, which configures a rotational center of the driving member, said driving member being characterized in that the shaft portion of the driving member is supported by the releasing member and in that a state where the shaft portion is supported by the releasing member is cancelled by a rotation of the releasing member in response to an operation of the door opening operation source.
