PROBLEM TO BE SOLVED: To provide a mechanical power generator utilizing wind force, which has high wind force utilization efficiency through its blades angle automatically shifting in response to the increase and decrease of wind pressure, and of which blades are not damaged by a strong wind. SOLUTION: The wind force generator having the constitution in which the blade angle are shifted by wind pressure variation, comprising: a coupling shaft supported by a boss in a rotary manner and is radially arranged, a pinion formed integrally with the coupling shaft, a rack housing fixed to the boss, a rack gear contained in the rack housing to be engaged with the above pinion where the rack gear can be slided, a spring inserted into a part of the rack gear which is extended to the outside of the rack housing, and a stopper screwed on the end of the part of the rack gear so that the spring can adjust elasticity. |
