Abstract

Setting position, direction and magnitude of compressive force applied to a crossing part. A joint with: crossing part in which first and second channels bored in casings cross on an XY plane; and pressure device holds casings from both sides with crossing part between the direction of the Z-axis perpendicular to the XY plane by a pressure member and applies compressive force to the crossing part, the pressure device with: a bored part h is formed in the casings, into which the pressure device is fitted and supports pressure; adjusting the compressive force, the pressure member is in position including an intersection of a peripheral wall of the first and second channels in the z-axis direction, an abutting part of the pressure member and bottom of the bored part presses intersection of peripheral walls; a noncontact part provided to the center preventing the center of the crossing part from pressing.

Dependent claims

A joint comprising;

a first channel and a second channel respectively bored in a casing;
a crossing part in which the first channel and the second channel cross on an XY plane;
and
a pressure device that holds the casing between by a pressure member from both sides with the crossing part between in a direction of the Z-axis perpendicular to the XY plane and applies compressive force to the crossing part,
wherein the pressure device is provided with:
a bored part which is formed in the casing, into which the pressure device is fitted and which supports the pressure device;
and
an adjusting device that adjusts the compressive force,
the pressure member is arranged in a position including an intersection of a peripheral wall of the first channel and a peripheral wall of the second channel in a view from the direction of the Z-axis, and
an abutting part of the pressure member and the bottom of the bored part presses a position matched with the intersection of the peripheral walls, the abutting part being provided with a noncontact part in the center for preventing a position matched with the center of the crossing part from pressing.
