PURPOSE:To attain the orientation of an armature in a proper state to an action gap by forming at least a flat standard surface for attachment to an attachment rod provided at the cantilever side and an attachment hole drilled at the knob member side respectively in order to prevent the relative variance of revolution between said rod and hole. CONSTITUTION:Both armatures 29 and 29 have 45 deg. cross angles to the virtual vertical surface including an axial line of a cantilever 25 and are orientated orthogonally to the axial line of the cantilever 25. A support wire 30 and an attachment rod 31 are formed in a body and concentrically with the axial line of the cantilever 25 at the rear end of a supporter 28. A metallic stopper pipe 32 is unified with the rod 31, and both the rod 31 and an attachment hole 33 have a right triangular form respectively. Thus the relative variance of revolution is avoided by each face of said right triangle. In such a way, the cantilever 25 can be attached quite easily to a knob member 21 without having a special angle control job.
