(EN) A hinge device, comprising a movable member (5) and a fixed member (6) rotatably connected to each other and a coiled spring (not shown) energizing the movable member (5) toward the fixed member (6). A storage recessed part (11) is formed in the opposed face (5b) of the movable member (5) to the fixed member (6), and a spherical body (8) is stored in the storage recessed part (11) movably in the peripheral direction of the movable member (5). A first cam part (13a) is formed on the opposed face of the fixed member (6) to the movable member (5). When the spherical body (8) strikes the first cam part (13a) by the rotation of the movable member (5) in the direction of an arrow, the cam part (13a) converts the energizing force of the coiled spring into a rotation energizing force. The rotation energizing force strikes the spherical body (8) against the first hammering part (11a) of the storage recessed part (11) at a high speed to generate click sound. ©KIPO&WIPO 2008
