置の構成とする。(Means for Solving the Problem) In a belt tension clutch configured to pull the tension pulley 5 elastically urged toward the belt 3 through the wire or the link 8 by the operation of the lever 7 and separate the tension pulley 5 from the belt 3, A torsion spring is provided between the lever 7 of the pivot 13 on which the lever 7 is loosely fitted and the fixing member 12 facing the lever 7.
15 is wound and one end thereof is locked to the lever 7 and the other end is locked to the fixing member 12 to elastically urge the lever 7 in the clutch engaging direction (a), and the guide groove 10 start end side of the lever 7 and the guide groove. A locking groove 17 communicating with the lever 7 is provided on the fixing member 12 side.
Is configured as an operating lever holding device for a belt tension clutch which is locked in the locking groove 17 against the elastic force of the torsion spring 15.

して極めて簡単である。(Effect of the Invention) Since the present invention is configured as described above, when the lever 7 is positioned at the clutch engagement position (A), the lever 7 is guided by the elastic force of the torsion spring 15 in the winding direction. It is held in contact with the end of the groove 10 and is in the clutch disengaged position (B).
When it is moved to the side and further positioned in the locking groove 17 on the side, the locking groove is generated by the elastic force of the torsion spring 15 in the compression direction.
It is held in contact with the side edge 17 and is always held in that position without any vibration, and its structure is much simpler than the conventional one.
