A coupling structure for coupling a first member and a second member includes a rod-shaped part configured to be received across a first hole formed in the first member and a second hole formed in the second member. The rod-shaped part has a first insertion portion configured to be inserted into the first hole of the first member, and a second insertion portion configured to be inserted into the second hole of the second member. The coupling structure further includes a fixing configuration, the fixing configuration being configured to fix the first insertion portion and the first member by applying an external force to the first insertion portion, and the fixing configuration being configured to fix the second insertion portion and the second member by applying an external force to the second insertion portion.

A hydraulic drive circuit is provided that can achieve high responsiveness, high precision, and high efficiency at a low cost in a hydraulic drive system popularly used in an industrial machine such as a press machine, a construction machine, and the like. A hydraulic drive circuitsupplies pressured liquid discharged from a main hydraulic pump P to drive a hydraulic actuator, and includes a first valvearranged in a main flow linethat circulates pressured liquid discharged from the main hydraulic pump P to the hydraulic actuator, a second valveto return the pressured liquid flowing into one liquid chamber of the hydraulic actuatorand discharged from the other liquid chamber to a tank T, and a sub-hydraulic pumpthat is arranged between the main hydraulic pump P and the drive direction control valveand uses the pressured liquid flowing in a branched flow linebranched from the main flow lineto increase a pressure and a volume of the hydraulic liquid in the main flow lineby predetermined quantities, respectively.
