A second hydraulic pressure switching valve 35 is attached to the main body.

なお、安全フレーム１５に下部取付孔１５ａ及び上部孔１５ｂを設けるにあたり、上下方向に所定間隔ずらして複数組設けると、オペレータの体格にあわせ適正な高さに第２油圧切替バルブ３５を取り付けることができる。   In providing the lower mounting hole 15a and the upper hole 15b in the safety frame 15, if a plurality of sets are provided with a predetermined interval shifted in the vertical direction, the second hydraulic pressure switching valve 35 can be mounted at an appropriate height according to the physique of the operator. it can.

また、バルブ取付プレート３６の左右外側下方から油圧ホース４１を上方へ延出し、バルブ取付プレート３６の屈折部上方を通して第２油圧切替バルブ３５のポートに接続している。   The hydraulic hose 41 extends upward from the lower left and right outer sides of the valve mounting plate 36, and is connected to the port of the second hydraulic pressure switching valve 35 through the upper part of the bent portion of the valve mounting plate 36.

前記構成によると、バルブ取付プレート３６の板厚を薄くしながら第２油圧切替バルブ３５を安全フレーム１５に圧接状態で揺れを防止しながら強硬に取り付けることができる。   According to the above configuration, the second hydraulic pressure switching valve 35 can be firmly attached to the safety frame 15 while being prevented from shaking in a pressed state while reducing the thickness of the valve mounting plate 36.
