PROBLEM TO BE SOLVED: To hold an object such as an operation lever or a hydraulic motor shaft whose inclining operation position or rotation position is changed at the changed position, release the object remaining held and adjust holding force in simple structure. SOLUTION: When a lever 76 for canceling holding force is shifted to a switch position 77a, the pressure of the hydraulic oil discharged from a pump 22 for an operation lever is applied to a piston 74. As a result, the piston 74 moves integral with an adjusting member 86 according to the force applied to the piston 74. As a result, an operation lever 6 is inclined, and if a support shaft 52 is rotated, the support shaft 52 stops at a rotation position, and the operation lever 6 is held at the operation position for inclination.
