Abstract
Provided is a connection structure of an operation rod in which a connection object such as a tip tool can be easily attached to and detached from the operation rod in a relatively short time without causing a fixed state. The main body is inserted into the cylindrical operation rod on the tip side. An engagement pair is formed of an engagement part with a notch provided to the main body on a tip side and an engagement part with an engagement pin provided to a tip tool. An inner slider on which a recessed groove is formed in a circumferential direction is relatively slidably disposed to the main body on an inner diameter side. An outer slider is relatively slidably disposed to the main body on an outer diameter side, wherein an opposing recess which can oppose to the recessed grove is formed on the outer slider.
