PURPOSE: A tubular joint of a fluid pressure apparatus is provided to prevent a tubular structure from sealing badly and to increase joining efficiency. CONSTITUTION: A tubular structure is installed in a recessed unit(29) with an insert member(28). The inserted part of the tubular structure is prevented from being short since the length is preset by the insert member. Thus, the tubular structure is installed in a tubular joint(12) with sufficient strength and then prevented from being spaced-apart from the joint. Also, an outer circumference(40) of a protrusion(36) of the insert member is stuck on an inner circumference of the recessed unit in order to prevent fluid from leaking to the outside from fluid channels(14,16).
