Cross shaft joint of vehicle

A cross shaft joint of a vehicle, comprising:

• a cross shaft provided on a power transmission path between a drive power source and a drive wheel, and including four shaft portions formed on two axes orthogonal to each other on one plane and extending radially around an intersection between the two axes;
• a first yoke rotatably supporting a pair of the four shaft portions formed on one of the two axes of the cross shaft;
• and a second yoke rotatably supporting a pair of the four shaft portions formed on the other of the two axes of the cross shaft, wherein the cross shaft includes a lubrication hole passing through the inside of each of the four shaft portions and which is in communication with a shaft end of the each of the four shaft portions, and the lubrication hole is filled with a lubricant, wherein
• the lubrication hole is formed at a position more distant, than a corresponding one of the two axes, from a position in a corresponding one of the four shaft portions to which a torque from the drive power source is transmitted through a corresponding one of the first and second yokes.
