Abstract: A loading operation vehicle can reduce a specific fuel consumption during a traveling time and can improve operability of a driving characteristic. The vehicle is provided with output characteristic changing means (38, 48) for changing an output characteristic of an engine (1) in a plurality of stages, shift timing changing means (39) for changing a shift timing of an automatic transmission (9) in a plurality of stages, working machine flow amount changing means (32, 50) for changing a working machine flow amount of a pressurized oil flowing through a working machine actuator (42) in a plurality of stages, mode setting means (40) for combining the output characteristic of the engine, the shift timing of the automatic transmission and the set value of the working machine flow amount with each other so as to set a plurality of modes, and mode selecting means (45) for freely selecting from the modes.

Abstract: There is provided a pressure sensing apparatus that does not trap any fluid within its flow path and has a simple construction so that it can be manufactured at reduced cost and has a diaphragm that operates stably. Such a pressure sensing apparatus comprises a sensor holder 21 having a flow path 22 arranged therein and provided with a flat surface area 25 and a sensor receiving hole 23 cut from the outer periphery of the sensor holder to the flat surface area 25 of the flow path 25. The apparatus also comprises a diaphragm 24 that is level with the flat surface area 25 and has an even thickness. A pressure sensor 31 arranged in the sensor receiving hole 23. Since a pressure sensing apparatus having a configuration as described above does not have any recess that can trap fluid within the flow path 22, it does not degrade the purity and cleanliness of the fluid running therethrough, if it is connected to a piping system for fluid that requires purging.
