Abstract: A negative pressure suction seal of the present invention is constituted by: a seal fixing portion; a seal expansion portion connected to the seal fixing portion; and a seal free end portion connected to the seal expansion portion. The seal expansion portion is constituted by a part that becomes narrow, approaching the object surface, from a part connected to an inner edge of the seal fixing portion. The seal free end portion is constituted by a part that expands further outward from the inner edge connected to the seal expansion portion. The seal fixing portion is fixed to a suction cup housing via a seal fixing plate member, and the position of an inner edge of the seal fixing plate member is outward of the position of the inner edge of the seal fixing portion. Frictional force between the negative pressure suction seal and the object surface is adjusted by increasing or decreasing the surface area where the seal fixing plate member presses upon the seal fixing portion.

Abstract: The three operations of hoisting, hoisting, and stopping are automatically performed by using the pulley and the position sensor, so that the general-purpose winch can be easily provided with the auto-tension function. The present invention provides the winch that is inexpensive and has the short delivery time. The three operations of hoisting, hoisting, and stopping are automatically performed by using the pulley and the position sensor, so that the general-purpose winch can be easily provided with the auto-tension function. In two pulleys where wire rope is suspended, the distance between the pulleys can be to changed according to the tension of the wire rope; if the tension increases, the distance between the pulleys decreases and the position sensor operates.
