The present paper gives the dynamics for the float-counterweight type wave energy conversion device which consists of pulley (s), wire (s), floats (s), counterweight (s), ratchet mechanism and tension pulley for the purpose of energy store. So far, authors have developed the mechanical dynamics model of the author's wave energy conversion device without tension pulley. The model has been found to be applicable by the preliminary test in the water tank experiment. However, it was recognized the wire between the driving pulley and the float can be slack in a period when water level is rising. This phenomenon is dangerous in operating the system, since wire suddenly changes form no tension state into stretched state when water level changes from ascending to descending. In this paper, the authors have developed the dynamics model which includes the effect of the tension pulley to prevent from the occurrence of wire slackening, and compared the results with those of the system without tension pulley.
