Abstract: A hinge unit is formed of a case with an inside wall, a rotating cam freely rotatably accommodated inside the case, a slide cam accommodated inside the case such that the slide cam is prevented from rotating relative to the case and is moved freely in an axial direction along the inside wall of the case, and an urging device accommodated inside the case to urge the slide cam toward the rotating cam. Cam surfaces are formed on the rotating cam and the slide cam to abut against each other. The cam surfaces has a contact range from a full-surface contact to a partial contact according to a relative rotational angle of the slide cam and rotating cam.

Abstract: A damper unit includes a gear having a core member projecting at a shaft core portion thereof and rotatably housed in a case, a string wound around the core member, a rotary damper engaging the gear for damping a rotational force of the gear, and a spring. One end of the spring is fixed to the case and the other end thereof is fixed to the core member so that an elastic force is accumulated when the string is pulled out.

Abstract: A damper includes a housing having a cylindrical shape and filled with a viscous fluid, a first rotor rotatably received in the housing and having a first connecting portion formed at an end portion thereof, and a second rotor rotatably housed in the housing coaxially with the first rotor and having a second connecting portion formed at an end portion thereof. The first and second connecting portions engage to allow the first and second rotors together, and forms a space therebetween to allow the viscous fluid to pass therethrough. An elastic member urges the first connecting portion and the second connecting portion to connect together, and accumulates an elastic force in a state that the connection between the first and second connecting portions is released.

Abstract: A damper includes a housing having a substantially cylindrical shape and filled with viscous fluid; a rotor portion rotatably supported inside the housing; fin portions projecting from the rotor portion; and deformable portions provided in the fin portions for changing a clearance between an end of the fin portion and an inner peripheral surface of the housing in response to resistance receivednulled from the viscous fluid. The deformable portion is provided in the fin portion to allow the fin portion to deform elastically in response to the resistance received from the viscous fluid, and to change the clearance between the end of the fin portion and the inner peripheral surface of the housing.
