Vibration-proof power take-off device for engine including two displacement absorbing joint members connected by a resilient member

A vibration-proof power take-off device for an engine comprising:

• resilient support means through which the engine is carried on a support;
• and
• a displacement absorbing joint for connecting an output shaft of said engine to a power take-off member, said displacement absorbing joint being comprised of a first joint member for connection to the output shaft of said engine, a second joint member for connection to said power take-off member, and a plurality of resilient members for resiliently interconnecting both the first and second joint members,
• wherein said second joint member is rotatably carried on said support through a bearing means,
• wherein said second joint member is disposed concentrical with said first joint member, and
• wherein said first joint member has a plurality of first radially projecting fins, and
• wherein said second joint member has a plurality of second radially projecting fins and wherein an intermediate member is provided and has a plurality of intermediate fins opposed to said first and second fins in a rotational direction of the joint, said plurality of resilient members being provided between said intermediate fins and said first and second fins, respectively, said intermediate fins being disposed concentrically with said first and second joint members.
