Document Type and Number:
Japanese Patent JP2019193972
Kind Code:
A
Abstract:
To provide a coupling device capable of simplifying coupling between a press-fitting providing unit and a coupling unit, and a pipe press-fitting coupling device using the coupling device.SOLUTION: A coupling device 300 includes a coupling tool 60 and a removable pin 90. The coupling tool 60 is installed on an outside surface of a cylinder block on one side with an installation hole 49 of the cylinder block included in a press-fitting providing unit 100 as the center, and a plurality of elastic coupling pins 80 are exposed to the installation hole. Then, the removable pin 90 is inserted into the installation hole 49 and an insertion hole of a coupling unit through an outside surface of the other cylinder block with the installation hole 49 as the center, elastically coupled with the plurality of coupling pins 80, and couples the coupling unit with the press-fitting providing unit 100.SELECTED DRAWING: Figure 5
