PROBLEM TO BE SOLVED: To further smoothly close a door while simplifying constitution. SOLUTION: A hinge device for a storage case comprises a housing 30 fixed to one of a body 2 and the door 3; a first hinge shaft 10 and a second hinge shaft 20 rotatably connected to both end sides of the housing 30 to be fixed to the other of the body 2 and door 3; a cam driving part provided at the first hinge shaft 10 inside the housing 30; and a torsion spring 100 with one end fixed to the second hinge shaft 20 and with the other end fixed into the housing 30 so that the rotational resistance of the door 3 is increased when the door 3 is closed and that the torsion spring is returned to its original state when the door 3 is opened.
