一連結部構造。A construction machine boom cylinder series connection structure in which hydraulic cylinders 4 for vertically swinging the boom 1 are pivotally connected to the left and right sides of the boom 1, and the small diameter portions-3a are located at both ends. , and a support shaft 3 provided with large-diameter portions 3b located between these small-diameter portions 3a, is passed through the boom 1 with each of the small-diameter portions 3a protruding from the boom 1. The diameter portion 3b is fitted inside and connected to the boom 1, the cylinder 4 is fitted onto the outside of the small diameter portion 3a so as to be relatively rotatable, and the side surface of the cylinder 4 is fitted onto the side surface 14 of the large diameter portion 3b. A construction machine boom cylinder series connection structure characterized by close proximity to each other.
