Abstract:
Provided is a rotary damper that makes it possible to easily adjust braking torque. A rotary damper that has a partitioning part and first and second adjustment bolts. The partitioning part has: first and second flow paths that connect regions of a partitioned cylindrical chamber; a first insertion hole that connects to the first flow path and to a first adjustment bolt screw hole of a case; and a second insertion hole that connects to the second flow path and to a second adjustment bolt screw hole of the case. The first adjustment bolt is screwed into the first adjustment bolt screw hole and is thereby inserted into the first insertion hole, and the length to which it protrudes into the first flow path can be adjusted. The second adjustment bolt is screwed into the second adjustment bolt screw hole and is thereby inserted into the second insertion hole, and the length to which it protrudes into the second flow path can be adjusted.
