专利汇可以提供Tension clutch structure专利检索,专利查询,专利分析的服务。并且PURPOSE: To make realization surely possible of a clutch off-condition by providing a clutch disconnecting means by which an operational member, while it is operated to a separation side of the first and second tension pulleys, is further displacement-operated to the upper.
CONSTITUTION: A connection point Z of operational members 16a, 16b is prevented from being displaced downward from above a center line X by own weight of the first/second tension pulleys 13a, 13b, etc., by press-spreading them by the operational members 16a, 16b to lift a connection point Y upward from the center line X. The first/second tension pulleys 13a, 13b are press-spread by an equal distance from the center line X, and power from a drive pulley 10 is cut off by weakening tension of a transmission belt 12. That is, turn operation and hand push operation of a walking type lawn mower are performed by operating one of the right/left clutch levers 19a or 19b to a position A to cut off power to one of the right/left rear wheels 2.
