Door hinge for vehicle, having check function

A door hinge for a vehicle, having a check function comprising:

• a vehicle body-side hinge member to be fixed to a vehicle body;
• a door-side hinge member to be fixed to a door;
• a hinge shaft that relatively rotatably connects between the vehicle body-side hinge member and the door-side hinge member;
• a movable member capable of being displaced in an axial direction substantially along the hinge shaft;
• an operation conversion device that converts a relative rotational movement between the vehicle body-side hinge member and the door-side hinge member into an operational force that is applied to the movable member and serves to displace the movable member substantially along the axial direction;
• and
• a check resistance application device that applies a retention resistance against the operational force applied to the movable member by the operation conversion device and thereby serves to resist displacement of the movable member along the axial direction, wherein
• the check resistance application device includes an elastic member that elastically deforms in a circumferential direction around the hinge shaft, corresponding to the axial direction displacement of the movable member;
• the elastic member extends along the axial direction of the hinge shaft;
• and
• the check resistance application device is provided with the elastic member and a stopper protrusion provided integrally with the elastic member.

• the check resistance application device is provided in a case that covers an entire axial movement path of the movable member;
• the case is sectionally formed in a square shape;
• and
• the check resistance application device is provided in a corner section of the case.
