ABSTRACT:
An object of the present invention is to provide a fastener made compact on the whole and capable of producing a strong fastening strength. To attain the object according to the invention, there is provided a fastener for being fitted to a fastening member (B) while continually exerting a tightening torque to the fastening member (B) fixedly screwed onto a mounting base, comprising a torsion coil spring formed in a winding shape so as to be inserted in an axial direction of the fastening member (B) into the fastening member (B) and having a fixing end (13) to be fixed onto the mounting base (A), and a detachable stopper (2) for restraining the torsion coil spring (1) in a state of accumulating a tightening torque.
