Spring 53, 54 biasing in the upright direction; a swivel base 60 for supporting the seam 5 provided on the support base 37 so as to be rotatable around the vertical axis 61;
The swivel base 6o is provided with a locking means 68 for locking the swivel base 60 at a pivot position about the vertical axis 61, and a lock release means 81 for unlocking the lock means 68 when the parallel link mechanism 36 is raised. An engaging tool 83 is provided that detachably engages with the parallel link mechanism 36 to allow elevation below the seat height, and a suspension spring 9o of the seat 15 is provided.
is attached to one side of the parallel link mechanism 36 and the vehicle body 1.

定しておき、またバックホー作業時には第１図及び第６
図の仮想線状態に固定しておく。(Function) Next, the method of action will be explained. The seat 15 is fixed in the solid line state shown in Figures 1 and 6 during loader work machine or regular operation, and is fixed in the solid line state shown in Figures 1 and 6 during backhoe work.
Fix it to the virtual line state shown in the figure.
実線状態ではロック手段６８により支持台３７と旋回台
６０とが旋回不能にロックされ、また係合具８３が平行
リンク機構３６の係合杆５２に係合している。In the solid line state, the support base 37 and the swivel base 60 are locked by the locking means 68 so as not to be able to rotate, and the engagement member 83 is engaged with the engagement rod 52 of the parallel link mechanism 36 .
この場合、支持台３７等は実線のシート高さから下方で

係合板５９が係合するため平行リンク機構３６はその状
態に保持される。When reversing the seat 15 back and forth from the solid line state to the imaginary line state, first pull the release lever 84 forward (in the direction of the arrow a in FIG. The seat 15 is rotated in the direction shown in FIG. Then, the springs 53 and 54 cause the front and rear links 38 and 39 of the parallel link mechanism 36 to move toward the pivot 4.
2.43, the parallel link mechanism 36 swings upward in the directions of arrows C and D, respectively, and the parallel link mechanism 36 stands up. When the parallel link mechanism 36 is in the upright state, the elastic engagement plate 59 engages with the engagement recess 58 of the positioning mechanism 57, so that the parallel link mechanism 36 is maintained in that state.

, and pulls the lock pin 76 downward (indicated by arrow e in FIG. 3) against the spring 79, thereby releasing the lock between the support base 37 and the swivel base 60 by the lock means 68. As a result, the swivel base 60 becomes freely rotatable, and since it is sufficiently raised by the uprighting of the parallel link mechanism 36, the seam 5 can be swiveled to the rearward position without coming into contact with nearby levers.

が着座する。When the seat 15 is reversed back and forth, the ball 72 of the positioning mechanism 67 engages with the engagement hole 70 to position the swivel base 60. Next, while resisting the springs 53 and 54, the parallel link mechanism 3
6 is tilted backward, the locking pin 7G of the locking means 68 engages with the engagement hole 75 by an operation opposite to that described above, thereby locking the swivel base 60 to the support base 37 so that it cannot rotate. Then, when the support stand 37 is placed on the pedestal 40 by further tilting it down,
The engagement tool 83 engages with the engagement rod 51 of the parallel link mechanism 36, and the support base 37 is fixed on the pedestal 40 so that it cannot move up and down, thereby completing the operation of reversing the sea H5 back and forth. During backhoe work, an operator sits on the seat 15 at this imaginary line position.

する。(Effects of the Invention) According to the present invention, there is provided a support base 37 supported on the vehicle body 1 via a parallel link mechanism 36 that is swingable in the front-rear direction, and a spring that biases the parallel link mechanism 36 in the upright direction. 53.5
4, a swivel base 60 for supporting the seat 15, which is provided on the support base 37 so as to be rotatable around the vertical axis 61, and a locking means 6 for locking the swivel base 60 in a swiveling position about the vertical axis 61.
8, one sheet 15 can be used by reversing it front to back. Furthermore, since there is only one sheet 15, there is no interference problem that would occur if two sheets were used. Furthermore, the locking means 68 is released by the lock release means 81 when the parallel link mechanism 36 is raised, and the lock release operation is not required and handling is easy. When the swivel table 60 is rotated, it is lifted by the parallel link mechanism 36, so it can be rotated without interfering with other members. In addition, a retainer 83 is provided on the swivel base 60 to detachably engage with the parallel link mechanism 36 so as to allow the seat to move up and down below a predetermined seat height. Since it is attached to one side of the vehicle body 1, a suspension effect can be obtained when the seat 15 is set at a predetermined height, improving the comfort.
