PROBLEM TO BE SOLVED: To provide a connection socket for electric components, improved in durability to vibration and impact in a simple constitution and easily releasing connection when force is applied in a removing direction such as attachment/detachment of a counterweight.SOLUTION: The connection socket for connecting a first electrical component fixed to the counterweight to a second electrical component on the machine body side includes a first member 1 and a second member 2. The first member 1 is formed into a column shape, and its outer peripheral surface 1b is provided with recesses 1a recessed in a perpendicular direction to an inserting direction into the second member 2. The second member 2 is formed into a hollow column shape having a hollow part 2a into which one end of the first member 1 is inserted. Further, the inner peripheral surface 2b of the hollow part 2a is provided with projecting members 3 engaged with the recesses 1a of the first member 1, and energizing means 4 for energizing the projecting members 3 to the recess 1a side. |
