The first rotary shaft 29 rotates around the fixed shaft 14 of the fixed shaft 14 and the shaft 27.
', the angle α between sides a and b becomes smaller,
The tips of the upper and lower links 17, 17', 19.19' will rise, and as a result, the holding members 9, 9'
is raised, further raising the height of the seat part 2 held therein by h.

It is pivotally supported by the shaft 13 via a boss 22, and a threaded portion 24 is screwed into a threaded hole 21 of the shaft 18 installed between the tips of the upper links 19 and 19'. The second rotating shaft 23 rotates around the fixed shaft 13 as a fulcrum, and the length d located between the fixed shaft 13 and the shaft 18 becomes longer than the length d', and the angle β between the sides a and e becomes larger. As a result, the fixed shaft 13 descends in the vertical direction using the fixed shaft 14 as a fulcrum.
これにともない保持部材９，９′も同時に傾斜し、さら

By reversing the rotating shaft 23, the length d of the second rotating shaft 23 located between the fixed shaft 13 and the shaft 18 is shortened to the length d'.
This is done by reducing the angle β between sides a and e.

In order to move the slide rail 6.6' of the seat portion 2 and the slide rail 11 of the holding member 9.9', the engaging portion is disengaged by operating the slide lever 12.
11' are slid relative to each other, and by operating the slide lever 12 at an appropriate position, the engaging portions are engaged and held.

決定されるものである。In the above embodiment, the angle is adjusted after the height of the seat portion 2 is adjusted, but the invention is not limited to this. Needless to say, the seat 10 is configured so that the seat portion can be adjusted in three directions as appropriate: front-rear direction, height adjustment, and angle adjustment, and the order of operation is as follows. It will be determined from time to time as appropriate.
この発明は上記のように構成されているので、座部部分

び角度調整を頻繁に行なうものに特に好適である。Since the present invention is configured as described above, when adjusting the height of the seat part, the seat part can be moved vertically without changing the angle, or the angle adjustment can be made by moving the seat part in the vertical direction. When doing this, you can adjust the height of the seat part as it is and change only the angle, independently of the height adjustment, and the adjustment process is extremely easy. This adjustment can be carried out quickly and reliably, and is particularly suitable for vehicles such as construction vehicles, ships, and other vehicles that require frequent height and angle adjustments.
