Reference numeral 4 denotes a cylinder body forming an oil chamber 5 therein, and a piston rod 6 whose base is inserted into the oil chamber 5 is attached to the tip of the cylinder body 4. They are slidably fitted. A cover tube 7 is supported at the tip of the piston rod 6 via a cover plate 8, which covers the tip of the piston rod 6 and the tip of the cylinder body 4, and whose base portion slides on the outer surface of the cylinder body 4.

Stopper pins 11, which are holding means, are placed at 0, 10...
By selectively inserting the stopper pin 1
1 and the tip of the cylinder body 4 to appropriately determine the amount of contraction of the piston rod 6.
尚、１２はシール部材である。 Note that 12 is a sealing member.

足されるものである。 By the way, in the above embodiment, the stopper pin 11
is engaged with the tip of the cylinder body 4, but an engagement hole into which the stopper pin 11 engages may be bored in the outer surface of the cylinder body. Further, in the embodiment described above, the cover tube 7 and the cylinder body 4 are fixed by the stopper pin 11 passing through the cover tube 7, but the structure is not limited to this. It will be satisfactory if a holding means is provided which can hold the extended position appropriately.
本発明は以上の構成で油圧ユニツトより圧油を

きる。 In the event that the hydraulic unit malfunctions during operation of the chute 2, the oil tank in the hydraulic unit and the oil chamber 5 of the hydraulic cylinder are switched to communicate with each other, and then the tip of the chute 2 is manually adjusted up and down. Once the desired height of the tip of the chute 2 is determined, the stop pin 12 is inserted into the through hole 10 adjacent to the tip of the cylinder body 4 and engaged with the tip of the cylinder body 4 to hold the chute 2 at the desired height. can do.
本発明は以上の如く、ミキサー車の油圧ユニツ
