A door hinge with a checker include: a first hinge arm and a second hinge arm which are connected to be relatively rotatable by a hinge pin; a check cam which is provided at the first hinge arm and has positioning recessed portions on its outer peripheral surface; a roller which moves on the outer peripheral surface of the check cam and engages with the positing recessed portions in accordance with relative rotation of the first and second hinge arms; and a torsion spring which resiliently urges the roller toward the outer peripheral surface of the check cam. A torsion shaft portion is connected via a reinforcing member to a free end part of a movable arm portion in the torsion spring. Thus, shaking of the door when the roller resiliently engages with the positioning recessed portion of the check cam by torsional load of the torsion spring is prevented. |
