Abstract: A lever displacement enlarging mechanism used for an optical stage positioning apparatus and provided with symmetrical levers adapted to transmit on an enlarged scale a displacement force of an actuator element, a distance between a front end of a boundary groove and an outer edge of a connecting column being set shorter than that between a rear end of the boundary groove and the outer edge mentioned above, in such a manner that a fulcrum hinge and a force point hinge are close to the outer edge of the connecting column, whereby a point-of-application hinge is positioned close to the axis of symmetry.

Abstract: An engine cooling apparatus which comprises an intercooler (3) for precooling a combustion air for an engine (1), an oil cooler (4) for cooling a working oil for a hydraulic excavator, a radiator (5) for cooling a cooling water for the engine (1), a cooling fan (17) which is a centrifugal fan, and a suction pipe (19) for directing a cooling air toward a suction side of the cooling fan (17). A bore (D1) at a downstream end (19A) of the suction pipe is smaller than a bore (D2) at a suction side end (18A) of a rotating shroud so that the downstream end (19A) of the suction pipe is disposed to enter inside the suction side end (18A) of the rotating shroud. Accordingly, noises are further reduced and an engine room (2) is made compact.
