UNIVERSAL JOINT STRUCTURE OF AUTOMOTIVE VEHICLE STEERING SHAFT TO BE POSSIBLE DEFLATION OF AIR

摘要

The present invention relates to a universal joint structure of a vehicle steering shaft capable of discharging air, and when the compression pressure of the air in the pipe is raised to a certain degree or more, it is immediately discharged to the outside so that the compressive force of the air does not pressurize the packing member.;The characteristic means for this is that the packing member 3 fitted to the end of the pipe 1 forms an air hole 3b, and the air hole 3b is connected to the contact end 2b of the shaft 2. It was to be supported.
