Document Type and Number:
Japanese Patent JP2016000964
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent damage to mechanisms such as a guide ring rotating to change the opening of a guide vane and a link coupling an arm to the guide ring.SOLUTION: A driving force transmission including a runner; a guide vane; an arm connected to the guide vane; a guide ring rotating to change the opening of the guide vane when water flows in the runner; and a link coupling the arm to the guide ring, comprises: a recess provided in one of the arm and the link; a protrusion piece 104 provided on the other part and fitted into the recess 110; and an elastic body 105 generating an elastic force so as to press the protrusion piece 104 and the recess 110 at a predetermined pressure, the protrusion piece 104 being detached from the recess against the elastic force of the elastic body 105 so as to disconnect the link from the arm if the arm does not react to the guide ring despite the rotation of the guide ring.
