Center bearing supporting device for propeller shaft

Claim 1

A center bearing supporting device for supporting a center bearing for a propeller shaft, said device comprising: an inner tube mounted on outer periphery of the center bearing; an outer tube connected to a vehicle body; an annular elastomeric insulator interposed between said inner and outer tubes and having an inner peripheral section secured to said inner tube, and outer peripheral section secured to said outer tube, and an intermediate section located between said inner and outer peripheral sections, said intermediate section bending in its axial direction along its whole periphery to form an annular projection coaxial with the center bearing, inner surface of said bending intermediate section defining an annular groove; and an elastomeric stopper disposed between said inner and outer tubes, said stopper being independent from said insulator and generally L-shaped in cross section, said stopper being positioned so as to have an inner peripheral section secured to said inner tube and an outer peripheral section forming a projection, a part of which is inserted into said annular groove and contactable with said inner surface of said insulator which defines said annular groove.
