Abstract: The present invention provides a thermally conductive composition comprising: (A) an organopolysiloxane containing at least two alkenyl groups, (B) a hydrogenorganopolysiloxane containing at least two hydrosilyl groups, (C) a thermally conductive filler, and (D) a polysiloxane compound containing at least one alkyl group having 4 or more carbon atoms. According to the present invention, it is possible to provide the thermally conductive composition capable of forming a thermally conductive member having an excellent thermally conductive property and high adhesive force to polypropylene.

Abstract: The present invention provides a rotary damper comprising a hollow housing (10) which is opened at its one end and completely closed at the other end by an end wall (11), a bearing (13) formed at the end wall (11), a shaft (20) fitted to the bearing (13), a plug (30) made of metal, having an aperture (31) supporting the shaft (20) and closing an opening in the housing (10), partitions (40) arranged inside the housing (10) for rotation in accordance with rotation of the housing (10), viscous liquid filling chambers (71 and 72) defined by the partitions (40), and metal vanes (51 and 52) arranged in the chambers (71 and 72) for rotation in accordance with the rotation of the shaft (20), wherein the vane (51 and 52) includes a check valve, the check valve includes a valve body (84), and the valve body (84) includes a stop 84c made of resin and arranged between the plug (30) and the vanes (51 and 52).

Abstract: A rotary damper has a cylindrical housing. A rotor is rotatably supported inside the housing for rotation with respect to the housing by a first bearing and a second bearing. The second bearing has a greater length in the axial direction of the rotor than the first bearing. The rotary damper can be employed in an opening and closing mechanism for a vehicle door.
