ABSTRACT:
This invention relates to a running exerciser and in particular to one including a base frame on which there is fixedly mounted a motor. An endless belt is carried on a front rod and a rear rod in the base frame. A driving wheel with a conical surface is mounted on an axle of the motor. A driven wheel is installed at one end of the front rod and has a conical surface. Between the driving wheel and the driven wheel is a controlling conical disc provided with a frictional ring on the circumference thereof which partially contacts the conical surfaces of the driving wheel and the driven wheel. When the controlling disc is slightly moved towards or away from the driven wheel, the interconnection among the controlling conical disc and the driving and driven wheels will be changed thereby effectively increasing or decreasing the speed of the running exerciser.
