Claims

[Scope of utility model registration request]

A bracket 1 that rotates left and right is supported on a vehicle body a by a support shaft c in the front-rear direction, and a support member 2 that supports the base end of an operating lever b is rotated back and forth by a support shaft d in the left-right direction. Support for free movement,
Near the bracket 1, there is a support shaft e in the left and right direction.
Rotating blocks 3 and 4 that rotate around the center are mounted on two parallel shafts on the left and right, and are connected to the respective spools 50 and 51 of the valve mechanisms V1 and V2 of the hydraulic switching valve device V, which are arranged in two parallel rows. On the support shaft e, intermediate rotation blocks 6L, 6M, and 6R are rotatably supported at intermediate positions between the rotation blocks 3 and 4 and at outer positions on the left and right sides, and an intermediate rotation block located at the center is supported on the support shaft e. The moving block 6M is connected to the support member 2 via the connecting link g, and intermediate rotating blocks 6 are located on the left and right outer sides.
A connecting link f
