Abstract

A door hinge device for vehicle includes a checking-force generating mechanism provided between an inner cylinder and an outer cylinder. The checking-force generating mechanism has a holding member attached to the outer cylinder, an elastic member biasing the holding member toward the inner cylinder, a detent roller being held in a holding groove of the holding member, and detent grooves that are provided in an outer peripheral surface of the inner cylinder and are capable of holding the door at a plurality of positions where the door should be stopped by an engagement with the detent roller. The detent roller applies a compression load to the elastic member even in a state where the detent roller is engaged with any of the detent grooves. An assembly groove is provided in the outer peripheral surface of the inner cylinder and allows the detent roller to be inserted into the holding groove in a state where the holding member is in contact with the outer peripheral surface of the inner cylinder. Accordingly, it is possible to exert an enough checking-force at a predetermined position where the door should be stopped and to allow the detent roller to be easily inserted into the holding groove at the time of the assembling.
