Claims

[Scope of claim for utility model registration] An outer cylinder suspended horizontally on a vehicle body frame, an inner cylinder that is telescopically inserted into the outer cylinder and has a jack hanging from its tip, and the inner cylinder is telescopically driven with respect to the outer cylinder. The outrigger device has a telescoping drive means, in which the outer cylinder is provided with a lock pin that is elastically biased toward the inner cylinder side and is capable of advancing and retracting, and the lock pin is further provided with a lever extending in the radial direction thereof. By rotating this and moving the lock pin forward and backward, the inner end of the lock pin is engaged with and disengaged from an engagement hole formed in the inner cylinder, thereby fixing and releasing the inner cylinder from the outer cylinder. In addition, in an outrigger device that controls on/off and driving direction of the telescopic drive means by rotational displacement of the lever, a position displaced from the rotational center of the inner end of the lock pin is in contact with the surface of the inner cylinder. An outrigger device characterized in that the contact surface is located on a side of the movement destination of the inner cylinder with respect to the rotation center when the lever is in a position where the inner cylinder is extended or contracted.
