Abstract
A rotary damper includes a driven-to-rotate member having integrally a driven-to-rotate part for coupling to a drive member and a first inner cylindrical wall, the first inner cylindrical wall including a locking part at a bottom end of the first inner cylindrical wall; 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; and a seal member 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. A viscous fluid is provided inside the receiving part for damping relative rotation between the driven-to-rotate member and the fixed support member.
Claims9
A rotary damper, comprising:
- a driven-to-rotate member having integrally a driven-to-rotate part for coupling to a drive member and a first inner cylindrical wall, said first inner cylindrical wall including a locking part at a bottom end thereof;
- a fixed support member for holding said driven-to-rotate member so as to rotate freely, said fixed support member having a circumferential recess for receiving the locking part;
- a receiving part formed between said fixed support member and said driven-to-rotate member;
- seal means for sealing an outer perimeter of said receiving part so that said driven-to-rotate member and said fixed support member are capable of relative rotation;
- and
- a viscous fluid received inside said receiving part for damping relative rotation between said driven-to-rotate member and said fixed support member.
