の姿勢変更装置。[Scope of Claim for Utility Model Registration] A pair of fixed arms that are attached to an agricultural working machine so as to protrude rearward, and a fixed arm that is pivoted at the lower part of the fixed arm so as to be able to swing vertically. , a pair of rocking arms whose rotational elasticity is biased downward by a spring, and a vertical shaft that passes through the tips of both fixed arms so as to be able to move up and down, and whose lower end is pivotally connected to the middle of the rocking arms. a lock member that is pivotally fixed to the distal ends of the two fixed arms and is rotatable between a position directly above the upper end of the vertical axis and a position away from the upper end of the vertical axis; and lower distal ends of the two swing arms. a leveling plate that is pivotally fixed across the entire length and can freely rotate up and down about the pivot part; and a leveling plate that can be pivoted in the length direction of the swinging arms at a position close to both swinging arms on the leveling plate. The lower end is pivotally fixed, and a long hole provided along the longitudinal direction is slidably fitted into a pin fixed to the swing arm, and a leveling plate is inserted into the upper end of this long hole by engagement with the pin. a posture holding plate having a bent portion that maintains the leveling posture of the leveling plate and a bent portion that maintains the leveling posture of the leveling plate by engaging with a pin at the lower end; and a bent portion of both posture holding plates that engages with the pin. It is composed of a spring that biases rotational elasticity in the direction, and an operating member that rotates both attitude holding plates so that the bent portions are separated from the pins, and the attitude holding plate and the locking member are moved to the leveling attitude of the leveling plate. This device for changing the attitude of a leveling plate for an agricultural working machine is such that the locking member is located directly above the vertical axis, and the locking member is in a separated position when the leveling plate is in the leveling attitude.
