Abstract: An air conditioning apparatus for a hydraulic shovel with which a wide space in a cab can be secured and a placement operation of ducts for distributing wind to each important point in the cab is facilitated. For this purpose, in the air conditioning apparatus, an air-conditioning unit (21) is placed at a front portion of a right side in a cab (10). The air-conditioning unit (21) is mounted to a front portion of a right side wall surface (51) of the cab (10). The air-conditioning unit (21) is mounted to the right side wall surface (51) of the cab (10) to be capable of being taken in and out from an inside and an outside of the cab (10).

Abstract: An operator cabin of a bulldozer is formed in a shape of truncated hexagonal pyramid having right and left supporting pillars at the utmost front side which slant forwardly from the top part to an intermediate part of the operator cabin and slant rearwardly from the intermediate part to the bottom part of the operator cabin while expanding so as to progressively widen the distance between the supporting pillars to expand a forward field of view from the operator cabin of the bulldozer to the front equipment, such as a blade, and substantially improve the visibility from the eye point of the operator to the front working equipment even during work at night.

Abstract: A device for fastening an ajar door of the operator's cab of a construction machine, which is small in size, presents a good appearance, and is easy to unfasten, has a plate support element (5) fixed to the outer surface of the operator's cab (2), a tubular support element (6) to hold the plate support element, a U-shaped striker (10) fixed to the plate support element, a lock (20) for holding the striker when the door is ajar, and a releasing lever (30) for releasing the lock from inside the operator's cab.

Abstract: A control lever for a transmission of a vehicle comprising a frame of the vehicle, a pair of rods pivotally connected to the control lever, which rods are arranged at right angles with each other, a housing fixedly secured to the frame, a spherical bearing for mounting the control lever on the housing, the spherical bearing comprising an outer race mounted in the housing, and a spherical bushing mounted on the control lever within the outer race so as to allow a sliding contact of the spherical bushing with the outer race, a cover fixedly secured to the control lever, which cover has a pair of guide slots formed therein positioned diametrically opposite sides to each other relative to the control lever, and a pair of guide pins fixedly secured to the housing, which guide pins are aligned with other in a direction parallel to one of the rods and adapted to be inserted within the guide slots.
