Claims

[Scope of utility model registration request]

A bending part that can be bent in the vertical direction is formed in the middle part of the boom that protrudes outward from the device body to the left and right, and the bending part is used as a fulcrum to move the tip side from the bending part toward the device main body. In a liquid spraying device whose boom can be folded and stored by swinging upward, a bending part that can be bent in the front and back direction is formed in the middle part of the boom, and the bending part is always kept in an unbendable state. A structure for preventing breakage of a boom in a liquid spraying device, characterized in that a bomb that biases toward the attitude side is provided, and the tip side of the boom is configured to be retractable and swingable in the front and rear directions.
