摘要： To provide a rotary damper in which a viscous fluid does not leak from between an inner end face of a land and an outer circumferential surface of a rotatable member, and a decrease in torque caused by an eccentric rotation of the rotating member is prevented. The rotary damper has a rotatable member being relatively rotatable with respect to a casing, the proximal portion of the rotatable member being accommodated in a chamber of the case; a ridge member extending axially along and projecting radially outwardly from an outer circumferential surface of the proximal portion of the rotatable member, the ridge member having a radially outer end face disposed for sliding contact with an inner circumferential surface of the chamber; and the land extending axially along and projecting inwardly from the inner circumferential surface of the chamber, the land having a face transverse with respect to the rotational direction of the rotatable member. The ridge member and the land divide an interior of the chamber into a compression compartment and a decompression compartment, the volume of these compartments being variable complementarily to each other in response to the relative rotation of the rotatable member and the casing. A spacer is interposed between the land and the proximal portion of the rotatable member and adapted to be pressed against the outer circumferential surface of the proximal portion and the transverse face of the land by the pressure built up in the compression compartment in response to rotation of the rotatable member.

摘要： A rotary damper has a casing having a fluid chamber filled with a fluid, a rotatable member disposed in the fluid chamber for rotation relative to the casing, a vane disposed on an outer circumferential surface of the rotatable member and extending in an axial direction thereof, the vane projecting toward an inner circumferential surface of the fluid chamber and having a first side and a second side opposite to the first side, a fluid passage for allowing the fluid to flow between the first side and the second side at or near a tip end of the vane, and a valve body mounted on the vane for selectively opening and closing the fluid passage. The valve body comprises a valve disposed in a position for closing the fluid passage and a spring for normally urging the valve in a direction to close the fluid passage. The valve and the spring are integrally formed. When the rotatable member rotates in a first direction, the valve opens the fluid passage against the urge of the spring under the pressure of the fluid on the first side of the vane. When the rotatable member stops against rotation, the valve instantaneously closes the fluid passage under the urge of the spring. When the rotatable member rotates in a second direction, the valve keeps closing the fluid passage under the urge of the spring and the pressure of the fluid on the second side of the vane.

摘要： A rotary damper for use with a toilet lid has a damper shaft rotatably supported by a damper housing, a collar of synthetic resin fitted over the damper shaft for rotation therewith, and a casing of synthetic resin fixed to the damper housing and disposed around the collar for rotation relative thereto. The collar has a pair of diametrically opposite axial ridges disposed on the outer circumferential surface thereof and projecting radially outwardly. The casing has a pair of diametrically opposite cantilevered resilient arms defined by respective slits in the circumferential wall thereof. The cantilevered resilient arms have respective axial teeth disposed on the inner circumferential surface of the casing and projecting radially inwardly for engagement with the axial ridges, respectively. When the collar rotates in one direction, respective slanting surfaces of the axial ridges engage and move over the respective axial teeth, displacing the axial teeth radially outwardly against the resiliency of the cantilevered resilient arms. After the axial ridges move past the respective axial teeth, respective step surfaces of the axial ridges are locked by the axial teeth, retaining the collar and hence the damper shaft in a rotated position unless strong forces are applied to rotate the damper shaft backward.
