摘要： A reduction gear is mounted on a revolving frame, and an electric motor having an electric motor shaft is disposed on the reduction gear. A hydraulic motor having a shaft is disposed on an upper side of the electric motor. A shaft insertion hole through which an upper end side of the electric motor shaft is inserted is provided in a lid portion of an electric motor casing. A male spline portion provided on the hydraulic motor shaft is spline-coupled to a female spline portion provided on the electric motor shaft. A bearing is provided between the shaft insertion hole and the electric motor shaft, and a pressure tight seal is provided by being located upwardly of the bearing. Hence, spline coupling portions of the female spline portion and the male spline portion are constantly lubricated by making use of drain oil which has leaked from the hydraulic motor.

摘要： An electric motor that is fixed to a revolving frame, an electrical equipment that is supported by the revolving frame by using a vibration absorption mount, and a cable for establishing a connection between the electric motor and the electrical equipment are provided. A connector mounting member having an outer shape smaller than that of a box is provided in the box of the electrical equipment, and an equipment-side connector is provided in the connector mounting member. A cable-side connector of the cable is connected to the equipment-side connector, and a cable end portion of the cable is fixed to the box by a clamp member. As a result, the vibration that is transmitted to the cable can be matched with the vibration that is transmitted to the cable-side connector.

摘要： The present invention provides a construction machine adopting a structure that assures a predetermined sound pressure level along a forward direction relative to the construction machine and allows a warning horn to be miniaturized. Warning horns 12 and 13 are mounted in the vicinity of at least either a left headlamp 9 or a right headlamp 10 provided on the left side and the right side of a vehicle body 3 of the construction machine. The warning horns 12 and 13 are housed inside a bracket 11 used to mount the headlamp 9 or 10. The plurality of warning horns 12 and 13 are disposed on a single side toward the left headlamp 9 or the right headlamp 10. Since a front attachment 7 does not block the sound generated from the warning horns 12 and 13 and thus the warning sound can travel without hindrance along the forward direction, a predetermined sound pressure level is achieved with ease along the forward direction relative to the vehicle body 3.

摘要： A lock mechanism (32) is constituted by a slide plate (36) with a slot (37) and a notched groove (39), and a lock pin (41) which is provided on the side of a console (24). Through the slot (37), the slide plate (36) is slidably supported on a couple of support projections (34) which are provided on the side of an operator's seat (7). By engaging the notched groove (39) with the lock pin (41), the console (24) is locked in an operating position. When an entrance gating lever (29) is manipulated by an operator, the slide plate (36) is pulled by a push-pull cable (43) to slide in a rearward direction against the action of a tension spring (42). Whereupon, the notched groove (39) is disengaged from the lock pin (41), and the console (24) is swung back into an upturned position by the action of a gas spring (28).
摘要翻译： 锁定机构（32）由具有槽（37）和缺口槽（39）的滑板（36）和设置在控制台（24）侧的锁定销（41）构成。 通过该槽（37），滑动板（36）可滑动地支撑在设置在驾驶员座椅（7）一侧的一对支撑突起（34）上。 通过将切槽（39）与锁定销（41）接合，控制台（24）被锁定在操作位置。 当操作者操纵入口门控杆（29）时，滑动板（36）被推拉电缆（43）拉动，以抵抗拉伸弹簧（42）的作用向后方滑动。 于是，凹槽（39）从锁定销（41）脱离，并且控制台（24）通过气弹簧（28）的作用摆回到向上的位置。
