To prevent one end of a torsion coil spring from coming off from a spring retainer plate part, even if a hinge device is subjected to an impact.

This hinge device 5 comprises: a first slender body 10 which is to be attached to a furniture body etc.; a second cup-like body 20 which is to be attached to a door etc. ; first and second links 30 and 40 for turnably connecting the second body 20 to the first body 10; and the torsion coil spring 70. One end 70a of the torsion coil spring 70 pushes the spring retainer plate part 32a of the first link 30, so as to turn and urge the second body 20 toward the first body 10. One end 70a of the spring retainer plate 70 is arranged between a side wall 12 of the first body 10 and a side wall 42 of the second link 40. Both the width of a gap between the spring retainer plate part 32a and the side wall 12 of the first body 10 and that of a gap between the spring retainer plate part 32a and the side wall 42 of the second link 40 are smaller than that of a wire at one end 70a of the torsion coil spring 70.
