In a constant-horsepower transmission having a primary pulley, a secondary pulley and a belt extended between the primary and the secondary pulley, a predetermined frictional force acting between the pulley and the belt is secured by an external instruction, and the pulley is capable of automatic alignment and shock absorption to ensure stable power transmission from the belt to the pulley. A first compressing device compresses an elastic device in response to an external instruction, a first pressing device including the elastic device applies a pressure and an elastic force produced by the compressed elastic device to the belt through the pulley. A predetermined frictional force is secured by the pressure and stable power transmission is insured by the elastic force. A first pressure application controller executes a variable pressure application control operation to apply an optional pressure to the belt by displacing or not moving the movable disk of the pulley.
