PURPOSE:To continuously detect the action force of a belt under a variety of operation conditions, during the drive at a relatively high speed. CONSTITUTION:A part of a metal block 30 is cut, and a strain gauge is attached on the cut part, and the external force applied to the metal block is detected by the strain gauge. Further, a resistor 54 for Wheatstone bridge, telemeter 53, telemeter driving battery 52 and a radio transmission antenna 51 are installed, and these are connected through signal lines 55, and detection value of the strain gauge which is sent as the radio signal from the telemeter 53 through the transmission antenna 51 is received by a receiving device 60 arranged in the vicinity of the metal V-belt, and the action force of the V-belt is detected from the received detection value. |
