FASTENING TOOL FOR FUEL CELL

摘要

A fastening tool for a fuel cell has socket members individually engaging with fastening members for simultaneously fastening a large number of unit cells layered on each other, a rotor provided on each socket member, torque input device for inputting torque for rotating each rotor, a torque transmission mechanism for dividingly transmitting the torque inputted from the torque input device to each rotor to uniformly rotate each rotor, and clutch mechanisms individually arranged between the socket members and the rotors. The clutch mechanisms rotate the socket members with the rotors when tightening torque to rotate the rotor is equal to or less than a predetermined value, and cause the rotors to run idle relative to the socket members when the tightening torque is greater than the predetermined value.
