<P>PROBLEM TO BE SOLVED: To provide a mechanism for easily adjusting a revolving inclination angle of a liquid jetting apparatus. <P>SOLUTION: The liquid jetting apparatus performs jetting a washing liquid such as collaborative oil, from a nozzle, to sludge deposited on the inside of an oil tank for cleaning. A top end rotary tube part of a liquid supply tube is rotated around an axis by a rotary shaft, and a jetting nozzle tube is revolved with an inclination end part as a rotary surface by a rotary cylindrical part top end. The rotary shaft comprises: a rotary shaft core 51; and a rotary shaft tube 52 containing the rotary shaft core 51. While rotating the rotary tube part 52 via the rotary shaft tube 52, the jetting nozzle tube is revolved via the rotary shaft core 51. An indicator mechanism comprises a first planetary gear mechanism 81 and a second planetary gear mechanism 82, which are equipped with sun gears receiving rotations of the rotary shaft tube 52 and rotary shaft core 51. The indicator mechanism indicates an inclination angle of the jetting nozzle tube toward a shaft line, and a switch mechanism facilitates setting of a swing angle of a liquid jetting nozzle. <P>COPYRIGHT: (C)2012,JPO&INPIT |
