ABSTRACT:
A retarding device for an exerciser includes a tubular housing, a drive shaft extending axially into the tubular housing and being movable axially therein, and a friction unit secured in the tubular housing and in contact with the drive shaft so as to resist axial movement of the drive shaft in the tubular housing. The tightness of contact between the friction unit and the drive shaft can be varied so as to vary correspondingly resistance to axial movement of the drive shaft.
