レキシブル継手が用いられている。2. Description of the Related Art In various kinds of torque transmitting mechanisms, ends of two rotating shafts are connected by a joint. For example, an output rotation shaft of an engine or a motor and an input rotation shaft of a pump are connected by a joint. In this case, it takes considerable effort to carefully install the engine, the motor and the pump so that the output rotary shaft of the engine or the motor is sufficiently aligned with the input rotary shaft of the pump. In addition, even if the installation is performed with sufficient care for such alignment, some eccentricity and declination remain between the two rotating shafts, and furthermore, the engine, the motor and the pump generate vibration during operation. Therefore, a flexible joint using a flexible member such as a spring or rubber has been used in order to absorb these at the joint portion.
