The present invention provides a door check device for installation between a motor vehicle body and a motor vehicle door that swings in opposing opening and closing directions relative to the vehicle body. The device comprises a first mounting structure that mounts on one of the vehicle door and the vehicle body and a second mounting structure that mounts on the other of the vehicle door and the vehicle body. The device also comprises first and second spaced apart cooperating structures and a link member having a detent provided on an intermediate portion thereof. The link member is received between the cooperating structures. The link member is carried by the first mounting structure and cooperating structures are carried by the second mounting structure such that the link member and the cooperating structures move relative to one another as the door is swung in the opposing opening and closing directions thereof. A spring structure is carried by the second mounting structure. The spring structure has first and second resilient torsionally deflectable biasing portions spaced apart and torsionally isolated from one another such that transmission of torsional stress between the torsionally deflectable portions is substantially prevented The biasing portions apply biasing forces to bias the cooperating structures into engagement with the elongated link member. Movement of the cooperating structures generally apart from one another individually torsionally deflects the biasing portions so as to individually increase torsional stress within the biasing portions and increase the biasing forces applied thereby.
