    摘要： An engine includes an EGR apparatus which refluxes a portion of exhaust gas from an exhaust manifold to an intake manifold as EGR gas. A differential pressure sensor detects a differential pressure between intake pressure of the intake manifold and exhaust pressure in the exhaust manifold. The differential pressure sensor is mounted on a head cover which covers an upper portion of a cylinder head. An intake pressure taking-out passage which is in communication with the intake manifold is formed in the cylinder head. An intake pressure introducing passage which is connected to the differential pressure sensor is formed in the head cover. The intake pressure taking-out passage and the intake pressure introducing passage are in communication with each other.

    摘要： A planetary gear reducer (1) includes: a sun gear (5) having external teeth and fixed concentrically to a power input shaft (3); a plurality of planet gears (7) having external teeth and mashing with the sun gear (5); a ring gear (9) having internal teeth and meshing with the planet gears (7); a planet carrier (11) configured to support a plurality of planet shafts (13), each of which is a rotational axis of a corresponding one of the planet gears (7), and to output revolution of the plurality of planet gears (7) as first power; and a cylindrical support (27) connected to the ring gear (9) such that the cylindrical support (27) is non-rotatable relative to the ring gear (9), the cylindrical support (27) being configured to output rotation of the ring gear (9) as second power. The cylindrical support (27) includes, at its one part along the direction of a central axis, a flexible structure (41) which is curved radially inward and has a V-shaped longitudinal section. This configuration makes it possible to both obtain rigidity and prevent misalignment while suppressing an increase in the weight of the gear reducer.

    摘要： A fluid pressure circuit that can, in either case where a first actuator that is fed from a first pump or a second actuator that is fed from a second pump is operated, by allowing feeding of the hydraulic fluid to a specific actuator from either the first or second pump, improve interlockability with the specific actuator. A control valve is incorporated with a plurality of first-group spools fed from a drive pump and a plurality of second-group spools fed from an idle pump. A solenoid selector valve unit switches a pilot line of a second-group tool controlling spool to a communicating state at the time of detection of a spool operation by a first pressure switch and switches a pilot line of a first-group tool controlling spool to a communicating state at the time of detection of a spool operation by a second pressure switch.

First bidirectional communication means (31, 71) having a high radio wave directionality and first automatic tracking means (32, 71A) are provided between the working machine (1) and the repeater station (7), and second bidirectional communication means (63, 76) having a high radio wave directionality, second automatic tracking means (63A, 76A), and emergency spread spectrum bidirectional communication means (64, 87) for enabling bidirectional communication between the remote control apparatus (6A) and the repeater station (7) when communication by the second bidirectional communication means (63, 76) is impossible are provided between the remote control apparatus (6A) and the repeater station (7). Consequently, even if communication between the working machine (1) and the movable repeater station (7) is disabled, each of the working machine (1) and the repeater station (7) is permitted to perform a minimum necessary operation, and any other person than those skilled in actual controlling operation of the working machine (1) can perform remote control easily.
