Abstract

PURPOSE:To effectively prevent the breakage of a supporter for outerboard motor by impaction and also prevent occurrence of noise by absorbing the impaction by providing a buffer elastic material between the middle of a bracket and the outerboard motor body. CONSTITUTION:In supporting holes 18 in front of vibration-insulating rubbers 21, small-diameter cylindrical rubber stoppers 25 are fitted on guide cylinders 17. Impaction caused by collision of the rubber stoppers 25 and the outerboard motor body 10 side, or the wall of the engine mount 4, can be absorbed. In short, when the outerboard motor body 10 side is in usual ships oscillation state, the support cylinders 17 do not collide against the wall of the engine mount 4, but when it is greatly oscillated beyond the usual state, the impaction is absorbed by the rubber stoppers 25, and the occurrence of noise and breakage by impaction can thus be prevented.

2. Description of the Related Art In outboard motors, the outboard motor main body is supported by a bracket that protrudes rearward from the hull side via vibration isolating rubber. In this case, this support part is supported at the center of gravity of the outboard motor body in order to prevent rolling vibrations around the engine crankshaft from being transmitted to the hull side, so that the outboard motor body itself is attached to the bracket. It is supported in such a way that it can swing horizontally to some extent. Therefore, there is a gap between the bracket 7) on the front side of this support part and the outboard motor main body, which may collide and interfere with each other and generate noise when the outboard motor main body swings significantly. , there is a risk of causing damage. The present invention
In order to eliminate such drawbacks, the present invention is designed to absorb the contact between the bracket and the outboard motor body side using an elastic body. The outboard motor main body is supported via a vibration isolating material at the tip of the support frame protruding rearward of the hull, and a shock absorbing elastic member is attached to the support frame between the support frame and the outboard motor main body. It is characterized by the fact that it has been provided.

As described above, according to the present invention, since the buffering elastic body is provided to the bracket between the intermediate portion of the bracket and the outboard motor main body, the outboard motor main body has a vibration isolating member that supports the outboard motor main body. Even when the bracket is swung from side to side, this elastic body absorbs the impact, effectively preventing noise generation and damage caused by impact. Since it only needs to be installed, its structure is simple and inexpensive.
