Provided is a closing locking device for a vehicle door. Even if a locking removing operating portion is wrongly operated, the locking state will not be removed. The closing locking device comprises a clamping member (22) installed upon the vehicle door of a vehicle, a to-be-clamped member that is fastened with the clamping member (22) when the vehicle door closes the doorway, and a locking removing operating portion (32) that can move to make the clamping member (22) move from the locking position to the locking removing position. The closing locking apparatus of the vehicle door further comprises an unlocking-banning mechanism (50) that bans the movement of the locking removing operating portion in the state that the clamping member (22) is located at the locking position. The unlocking-banning mechanism (50) adopts a structure that is capable of removing the movement-banning state of the locking removing operating portion (32) by a manual operation of continuously applying force to the unlocking-banning mechanism (50) in the constant direction.
