摘要： 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.

摘要： A rotary damper (D) is constituted by: housings (11, 51); a silicon oil (21) being housed inside the housings (11, 51); a rotor (31) wherein a resistive portion (36) moving through the silicon oil 21 inside the housings (11, 51) is provided in an axial portion (32) which is housed inside the housings (11, 51) and projects from the housings (11, 51); and an O-ring (61) preventing the silicon oil (21) from leaking between the axial portion (32) and the housing (51), and multiple arc-like through-bores (37) are provided in the resistive portion (36) on a concentric circle, and depressed grooves (38) communicating with the arc-like through-bores (37) are provided. Accordingly, during the assembly, the air being mixed into the housing is not allowed to be excessively compressed, so that even if the rotor rotates bi-directionally, the noise being caused by the air being mixed into the housing can be prevented.

摘要： A rotary damper includes a driven-to-rotate member with a driven-to-rotate part for coupling to a drive member, a fixed support member for holding the driven-to-rotate member so as to rotate freely, a receiving part formed between the fixed support member and the driven-to-rotate member, a seal for sealing an outer perimeter of the receiving part so that the driven-to-rotate member and the fixed support member are capable of relative rotation, and a viscous fluid inside the receiving part for damping the relative rotation between the driven-to-rotate member and the fixed support member. The rotary damper is easy to assemble by virtue of eliminating the accumulation of unwanted air inside the receiving part. Since air does not mix with the viscous fluid, the torque precision can be made constant.

摘要： A rotary damper includes a driven rotary member having a driven rotary part for engaging a driving member, and a stationary support member for rotatably supporting the driven rotary member. A housing is disposed between the stationary support member and the driven rotary member, and a viscous fluid is disposed in the housing for damping the driven rotary member when the driven rotary member rotates relative to the stationary support member. A sealing member is disposed on the housing for sealing an outer peripheral edge of the housing so as to allow the driven rotary member to rotate relative to the stationary support member. An opening is formed in the driven rotary member or the stationary support member for communicating a portion of the housing inside the sealing member with atmosphere. The opening is closed when or after the driven rotary member and the stationary support member are assembled.
