Steering joint device for a car

A steering joint device for a vehicle, comprising:

• a first universal joint constructed to be connected to a steering shaft,
• a second universal joint constructed to be connected to a shaft of a steering device side, and
• an anti-vibration device connected between said first universal joint and said second universal joint,
• characterized in that:
• said first universal joint comprises a first yoke member constructed to be connected to the steering shaft, a second yoke member connected to said anti-vibration device, and a first cross shaft member connecting said first yoke member to said second yoke member;
• said second universal joint comprises a third yoke member constructed to be connected to the shaft of the steering gear device side, a fourth yoke member connected to said anti-vibration device, and a second cross shaft member connecting the third yoke member and the fourth yoke member;
• and
• each of said second yoke member and said fourth yoke member has a bottom plate portion in which two holes are formed axially symmetrically on a straight line which makes a predetermined angle θ (where 0<θ<90°) with a straight line obtained by projecting, onto that bottom plate portion, an axial line of a shaft pivotally supporting a corresponding one of said first and second cross shaft members to that yoke member;
• and
• said anti-vibration device is connected by first pins to said bottom plate portion of said second yoke member through the two holes thereof, and connected by second pins to said bottom plate portion of said fourth yoke member through the two holes thereof, the straight line on which the two holes of said bottom plate portion of said second yoke member are formed being oriented at a right angle with respect to the straight line on which the two holes of said bottom plate portion of said fourth yoke member are formed.
