ことが挙げられる。In the connection structure between the hull and the outboard motor, the propulsion force of the outboard motor is effectively transmitted to the hull without waste at the time of propulsion. What does not transmit vibration to the hull is desired. For this reason, even in the above-described prior example, vibration is absorbed by interposing an elastic body in the connecting portion. However, since transmission of propulsion and prevention of vibration transmission are contradictory, a sufficient effect is obtained. Is not obtained. In addition, considerable effort is required to set the spring characteristics of the elastic body. Further, the following is another problem.

The torque roll axis is substantially near the vertical axis or at a position slightly behind it. However, in the conventional connection structure, the position of the upper mount or the lower mount is restricted by the peripheral wall of the extension case spaced apart so as not to interfere with the vertical axis, and is set at a position somewhat separated from the torque roll axis. . As a result, the rigidity of the elastic body made of rubber or the like is increased, and the purpose of supporting the own weight of the outboard motor, the purpose of obtaining a favorable steering feeling, and the purpose of preventing transmission of vibration are simultaneously achieved. Making it difficult.

2, 103a-3 are partially brought into contact with the inner surfaces of the respective storage portions 104 provided on the left and right portions of the extension case 8. The partial contact makes it easier to deform and exerts a soft damping characteristic when the compression force acts, as compared with the case where the entire surface comes into contact, and absorbs vibration. In particular, the protruding portions 1103a-1 on the front and rear surfaces are completely crushed when the propulsion force is increased, and the front end surface or the rear end surface of the rubber main body 103a abuts entirely on the inner surface of the storage portion 104 and becomes rigid. And the transmission of forward or reverse propulsion is efficiently performed. In the example shown,
Although the elastic portion 103 is provided with a convex portion so as to partially contact the inner surface of the storage portion 104, a convex portion may be formed on the inner surface of the storage portion 1044 to partially contact the inner surface.

The entire surface of the concavo-convex part facing the storage part will be in contact with eliminating the gap between the concavo-convex parts, the rigidity of the elastic body will increase,
Propulsion force is transmitted efficiently. Therefore, when the thrust of the outboard motor is small, such as in the low rotation range of the outboard motor, the function of the surface that is always in contact between the elastic body and the storage portion exerts a soft buffering characteristic in the thrust direction, In the low rotation range and when the thrust is small, the outboard motor can sufficiently absorb vibration. When the propulsive force transmitted from the outboard motor to the hull increases, the contacting parts between the elastic body and the storage part when the thrust is large come into contact, exhibiting rigid characteristics in the thrust direction, and effectively Propulsion force can be transmitted.

造。1. A bracket for a hull, and an outboard motor body rotatably supported on the bracket so as to be rotatable left and right about a swivel shaft. The bracket provided on the swivel shaft and the outboard motor body are elastically connected. In the coupling structure of the outboard motor connected via the mount, via an elastic mount, a bolt member protruding toward the outboard motor main body is provided on left and right sides of a bracket provided on the upper part of the swivel shaft, and an outer peripheral portion of the bolt member is provided. Is provided with an elastic body, the elastic body is housed in storage sections provided on the left and right of the front part of the outboard motor main body, and the bracket and the outboard motor main body are connected via the elastic body. On a surface orthogonal to the thrust direction, a concave and convex portion is provided on both the surface of the elastic body and the opposing surface of the elastic body of the storage section that stores the elastic body, the surface being in contact with the surface of the elastic body. And the opposite side of the storage section A connection surface via an elastic mount of the outboard motor, wherein the connection structure is provided with a surface that contacts when the thrust increases.
