Claim:
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 a 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 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 movable member is capable of moving over an axial movement path along the axial direction, and a resistance application section of the check resistance application device is provided in a plurality of locations over said axial movement path, the operation conversion device includes a guide portion that is formed on the outer circumferential surface of the hinge shaft and gradually inclines in a spiral manner along the axial direction of the hinge shaft, and the movable member is displaced in the axial direction of the hinge shaft by being guided by the guide portion.
