Abstract
A hydraulic oil storage device and an injection molding device are provided with a connection box that partitions a storage region of a sub-tank into a first region that includes a flow channel opening portion for a coupling tube and a second region other than the first region, in which the connection box is provided with an internal region communication portion that brings the first region and the second region into communication, and causes a pressure loss equal to the pressure loss of the coupling tube, or a pressure loss greater than that pressure loss, and a return tube is connected to the sub-tank so that the flow channel outlet faces the first region.
