Claims

[Scope of Claim for Utility Model Registration] 1. An outrigger box fixed to the vehicle body, an outrigger beam that is telescopically inserted into the outrigger box and can be extended to the side of the vehicle body, and a jack attached to the tip of the outrigger beam. an outrigger extended position detector for detecting the extended position of the outrigger beam, the outrigger device comprising: a cam member attached to one of the outrigger box and the outrigger beam, and a cam member attached to the other of the outrigger beam; a plurality of switches that are turned on and off by the cam member according to the expansion and contraction of the switch;
a determining device that determines which of a plurality of extended positions the outrigger beam is located in between a fully retracted position and a fully extended position based on a change in the combination of off signals; An outrigger extension characterized in that the extension positions other than the fully extended position are set to have predetermined widths, and at least two combinations of on/off signals of the switch are set within each predetermined width. position detector. 2. A combination is set in which all of the switches are turned on in the fully retracted position, and a combination is set in which all of the switches are turned off in the fully extended position. Outrigger extension position detector as described.
