れぞれ掛止して構成するのである。 Reference numeral 1 in the figure shows a seat. A support member 2 having a groove-shaped cross section is fixed to approximately the center of the lower surface of the seat 1, and a pair of support plates 3 and 3' facing each other are protruded from the seat 1. , one side of the upper part of the support plates 3, 3' is pivotably pivoted by a support shaft 5 on one side of the upper part of a pair of substrates 4, 4' interposed between the support plates 3, 3'. The substrates 4, 4' were mounted opposite to a pair of upper and lower horizontal plates 7, 7' attached to the upper end of the leg rod 6, and were fixed to the leg rod 6 via the horizontal plates 7, 7'. At the lower part of the upper part of the substrates 4, 4' on the other side opposite to the one side, there are formed inclined elongated holes 8, 8' which are elongated in the direction toward the support shaft 5. A support hole 9 is provided protruding from the peripheral end of the oblique elongated hole 8 provided in one of the substrates 4 protruding from the support plate 3, and the tip of an operating lever 10 pivotably pivoted to this support piece 9 is attached. the oblique long hole 8;
8', and the tip 10' of the operating lever protruding from the other base plate 4' is movably engaged in an engaging edge 11 provided on the other support plate 3'.
The end edge thereof is inclined in the direction of the support shaft 5, and
At this position, an appropriate number of locking edges 12, 12, 12 are formed to match the oblique elongated holes 8, 8', and a coil spring 13 is arranged between the leg rod 6 and the other base plate 4'. One end of this spring 13 is hooked to the upper horizontal plate 7, and the other end is hooked to the operating lever 10.

維持されるのである。 When the tip 10' of the operating lever is released from the locking edge 12 at this position against the force of the spring 13, the support plates 3, 3' tilt around the support shaft 5.
Therefore, the seat 1 is tilted at a desired angle, and when the tip 10' of the operating lever 10 is engaged with the other locking edge 12 that has been moved to this position, the seat 1 is tilted at a desired angle.
The set angle is maintained by the coil spring 13.

本考案は前記の通りの構成であるから、操作レ
バーの操作によつて座盤の傾斜角度を自由に設定
でき、しかも、構造が簡単で実用的である。 Since the present invention has the above-mentioned configuration, the inclination angle of the seat can be freely set by operating the operating lever, and the structure is simple and practical.
