A rotary viscous damper having a disc surrounded by a housing and cover, the disc rotatable with a shaft which penetrates the housing, a gap provided between opposite sides of the disc and the inside surfaces of the housing and cover for receiving viscous fluid, and triangularly shaped indentations formed on opposing surfaces of the disc and the housing and cover, the indentations on the housing and the cover arranged at selective rotational positions. Rotation of the disc aligning opposing indentations on the discs and the housing and cover to create a rotary position of minimum torque and when misaligned, a rotary position of maximum torque. The oscillating torque value creates a nominal torque associated with the damper, but can be selectively installed to present a minimum torque at a particular rotational position. The invention is particularly adapted to rotary devices where rotational position can effect the available torque for driving the shaft, such as an exercise bicycle.
