Claims

[Claims for Utility Model Registration] 1. A swing control mechanism A that controls the left and right swing of the backhoe device 11 and a swing control mechanism B that controls the swing of the backhoe device 11 are provided, and these swing control mechanisms A and a backhoe device in which a restraining mechanism 30 that selectively restricts the operation of the turning control mechanism B is activated by pushing a restraining foot pedal 28, which is swingable from side to side, to either the left or right side. The left/right rocking and turning operation switching device includes a pivoting device for pivoting the foot pedal 28 such that the foot pedal 28 is located on one side of the left and right with respect to the rocking axis R, and the foot pedal 28 can be moved to the other side. A switching device for left/right swinging and turning operation of backhoe equipment. 2. Lateral rocking of the backhoe device according to claim 1, wherein the foot pedal 28 is formed of a single pedal member 28a located on one side of the left and right sides of the rocking axis R. and swivel operation switching device. 3. Two pedals in which the foot pedal 28 is pivotally supported on either the left or right side with respect to the rocking axis R, and is independently repositionable to the other left or right side with respect to the rocking axis R. The left-right swing and swing operation switching device for a backhoe device according to claim 1, which is formed from members 28a and 28b.
