PURPOSE:To transmit a thrust of an outboard motor so efficiently by installing an elastic body part at the outside of an inner member of an elastic mount, while installing a flange part in this elastic body part in the inner member, and constituting it so as to regulate any compressive deformation in this elastic body. CONSTITUTION:When an outboard motor 8 is driven and a thrust works on a connecting part 7 between this motor 8 and a hull 1, an elastic body par 15 in this connecting part 7 compressed and deformed by this thrust. At this time, an intermediate flange part 17 embedded in this elastic body part 15 is connected to an inner member 12 of an elastic mount, so that a deformation value of the elastic body part 15 is regulated, and thereby rigidity in the compression direction comes high, thus transmission of the thrust is efficiently performed. When vertical or longitudinal vibrations works on this connecting part, the elastic body part 15 is extended (shearing) and deformed, but since a recess is formed between the elastic body part 15 and a casing 16, this deformation is promoted, thus the vertical or longitudinal vibrations are effectively absorbed. |
