真正、１７の止付作業を容易に行なうことができる。First, in the device 14, the connecting tool 17 is set in the state where the operating screw rod is in the most retracted state as shown in FIG. 7(a), and the first ladder mounting plate 4 is set in the state shown in FIG. In this state, connect the connectors 16 and 17 to the connecting arms 8, respectively.
, fasten to the frame body 3. In this case, since the rod 4 is at the maximum extension point with respect to the cylinder, the movement of the piston to the left in Figure 7 is stopped by the graph in Figure 7. As is clear from point (a), the compression spring device 14 does not have an expansion force. Therefore, the work of fixing the connection piece 17 can be easily performed.

尚上記のような収縮の操作は圧縮ばね装置１４が所要の
伸長力を示す状態となる点まで行なえばよい。The contraction operation as described above may be performed until the compression spring device 14 exhibits the required extension force.
上記のような操作によシ、圧縮ばね装置１４は梯子取付
板４が第２図の位置におる状態で既に大きな付勢力を連
結腕８を介して取付板４に与えている。As a result of the above-described operation, the compression spring device 14 applies a large biasing force to the mounting plate 4 via the connecting arm 8 even when the ladder mounting plate 4 is in the position shown in FIG.
従って前述の如く容易に梯子取付板４の上げ下げ操作を
行なうことができる。Therefore, as described above, the ladder mounting plate 4 can be easily raised and lowered.
