A hinge device includes a cylindrical space between a hinge tube and a hinge shaft, and a cylindrical body fitted to the cylindrical space. The hinge device further includes a recessed portion formed at an end edge of the cylindrical body, stepped portions formed at both ends of the recessed portion in a circumferential direction, and a pin. The hinge tube and the cylindrical body generate rotational friction resistance by a relative rotation thereof. The cylindrical body rotates relative to the hinge shaft. The pin is situated in the recessed portion. The pin contacts with either of the stepped portions by a relative rotation of the hinge shaft and the cylindrical body.
