つた。 The conventional outrigger device, as shown in Fig. 4,
an outer cylinder 1 horizontally fixed to the vehicle body (not shown);
The inner cylinder 4, which is telescopically fitted into the outer cylinder 1 and has a ground plate 6 at its lower end, is prevented from protruding upward from the upper side of the inner cylinder 4. The outer cylinder 1 has the inner cylinder 4 at the upper inner side of its outer end.
It is provided with a support part 7 facing the upper surface thereof, and an upper roller 2 facing the upper surface of the inner cylinder 4 at the base end of the inner cylinder 4 when the inner cylinder 4 is extended with respect to the outer cylinder 1. In addition, the outer end of the lower plate 8 is cut out, and the inner cylinder 4 is separated from the outer cylinder 1.
When fully contracted, the cylinder 5 is positioned below the support portion 7 of the outer cylinder 1. And in the outer cylinder 1,
A lower roller 3 is provided to support the lower surface of the inner cylinder 4 near the inner side of the cylinder 6 (near the proximal end of the inner cylinder 4) when the inner cylinder 4 is completely contracted relative to the outer cylinder 1. The weight of the inner cylinder 4 is supported by this. However, in such a conventional configuration, in order to ensure the amount of extension of the inner cylinder 4 with respect to the outer cylinder 1, the distance l' between the upper roller 2 and the lower roller 3 is reduced, and as a result, the inner cylinder 4 overhangs. At times, the force acting on the upper roller 2 and the lower roller 33 increases, resulting in a disadvantage that a large operating force is required to extend and draw the inner cylinder 4.
本考案は、上記せる従来技術の欠点を解決する
ためになしたものである。 The present invention has been made to solve the above-mentioned drawbacks of the prior art.

う構成したものである。 That is, the outrigger device of the present invention includes an outer cylinder horizontally fixed to the vehicle body, an inner cylinder telescopically inserted into the outer cylinder, and a jack cylinder having a ground plate at the lower end at the tip thereof. and an inner cylinder that is vertically disposed so as not to protrude upward from the upper surface of the inner cylinder, and the outer cylinder has a support portion at the inner upper part of the outer end thereof, facing the upper surface of the inner cylinder. and an upper roller that faces the upper surface of the inner cylinder at the proximal end of the inner cylinder when the inner cylinder is extended with respect to the outer cylinder; In an outrigger device configured such that when the inner cylinder is completely contracted with respect to the cylinder, the jack cylinder can be positioned below the support portion of the outer cylinder, and the inner cylinder is arranged in the direction of expansion and contraction of the inner cylinder. The outer cylinder has a lower surface that extends along both sides of the jacket cylinder, and when the inner cylinder is completely contracted in the outer cylinder, the jacket cylinder on the lower side of the inner cylinder is attached to the outer cylinder. The structure is characterized in that the lower rollers are arranged in such a positional relationship that they support both sides of the roller.
この構成により、上部ローラ２の位置を変更す

筒１に対する張り出し引き込みに要する操作力が
小さくなるのである。 With this configuration, it is possible to set a large distance between the upper roller 2 and the lower roller 3 without changing the position of the upper roller 2, thereby reducing the force acting on the upper roller 2 and lower roller 3 when the inner cylinder 4 is extended. As a result, the operating force required to extend and pull the inner cylinder 4 into and out of the outer cylinder 1 is reduced accordingly.
次に実施例について説明する。１は車体に横架

備えたジヤツキシリンダ５を、当該内筒４の上側
面から突出しないようにして垂設している。 Next, an example will be described. Reference numeral 1 denotes an outer cylinder which is horizontally fixed to the vehicle body, and 4 is an inner cylinder which is telescopically inserted into the outer cylinder 1. A jack cylinder 5 having a ground plate 6 at the lower end is attached to the tip of the inner cylinder. It is hung vertically so as not to protrude from the upper side of the cylinder 4.

外筒１に設けられた上部ローラである。 Reference numeral 7 denotes a support portion provided at the upper inner side of the outer end of the outer cylinder 1 so as to face the upper surface of the inner cylinder 4. 2 faces the upper surface of the inner cylinder 4 at the base end of the inner cylinder 4 in a state where the inner cylinder 4 is extended with respect to the outer cylinder 1,
This is an upper roller provided on the outer cylinder 1.

もつて下部ローラ３を配置している。 The outer end of the lower plate 8 of the outer cylinder 1 is cut out, and when the inner cylinder 4 is completely reduced relative to the outer cylinder 1, the jack cylinder 5 is attached to the outer cylinder 1.
It is designed so that it can be located at a position below the support part 7 in . The lower side surface 9 along the expansion/contraction direction of the inner cylinder 4 has both side edges connected to the jack cylinder 5.
When the inner cylinder 4 is completely contracted in the outer cylinder 1, the outer cylinder 1 has a position on both sides of the jack cylinder on the lower surface 9 of the inner cylinder 4, respectively. The lower roller 3 is arranged in such a positional relationship as to support it.

う利点をも有している。 Due to this configuration, as is clear from Fig. 3, which shows the present invention in comparison with the conventional example shown in Fig. 4, the position of the lower roller 3 in the present invention can be attached closer to the outer end of the outer tube 1 than in the conventional example, and the distance l between the lower roller 3 and the upper roller 2 can be significantly increased compared to the conventional example. Therefore, the operating force required to extend and retract the inner tube 4 can be reduced.
Furthermore, according to the present invention, the force acting on the upper roller 2 and the lower roller 3 is smaller than that of the conventional device, which has the advantage that the life of each roller 2, 3 is correspondingly longer.
