Description of the Related Art Conventionally, an elastic force coupling having a single torsion spring constant is used for a transmission portion between an engine flywheel and an output shaft marine gear / propeller of a ship, and is configured to transmit power. ing. Also, in the shaft coupling transmission using the intermediate shaft, elastic couplings with a single torsion spring constant are mounted in series on both sides of the intermediate shaft,
The transmission was made by reducing the torsional spring constant of the transmission system. Japanese Patent Application Laid-Open No. 8-473 discloses a two-stage torsion spring constant in which a plurality of elastic bushes having a small spring constant and a plurality of elastic bushes are used, and a plurality of elastic bushes are alternately inserted between an engine flywheel portion and an output shaft member. An elastic coupling comprising: The elastic coupling is configured such that an elastic bush having a small spring constant acts when the engine speed is low, and an elastic bush having a large spring constant acts during load operation. Thus, conventionally, the engine flywheel and the output shaft marine gear
An elastic coupling is attached to the connection with the propeller to reduce the natural frequency in the transmission system. The maximum resonance point with the torque fluctuation frequency generated from the engine is designed so as to be out of the normal operation range, and the adverse effect due to the resonance is eliminated.

When energy saving operation of an engine of a ship or other work is performed with an auxiliary machine or the like, no-load operation may be performed at a low engine speed of less than low idle. In this case, the torsional resonance point in the low-speed rotation range may be approached, and the noise may be generated from the output shaft marine gear or the like, or the vibration may increase to cause damage to the parts. At the time of low-speed no-load operation of the engine, the flywheel effect is also reduced and the rotation fluctuation is increased. In order to solve this, it is desired that an elastic member having a considerably low torsion spring constant is required and that there is no backlash. The present invention aims to solve these problems.
