Abstract
A steering structure of a personal watercraft comprising, a mount member 3 provided on a mount base 2 on an upper portion of a deck 1, a hold member 8 provided inside of the deck separated downward from the mount members 3 by a predetermined distance, a handle support shaft 4 supported by the hold member 8 and the mount member 3, and a support collar 11 provided at the handle support shaft 4, for rotatably supporting the handle support shaft 4, and for absorbing a deviation of support positions of the handle support shaft 4.
Claims9
A steering structure of a personal watercraft comprising;
- a one-piece mount member provided on a mount base formed on an upper portion of a deck of the watercraft, said one-piece mount member having a spherical body with a central spherical aperture and including perimeter mounting means for mounting said mount member to said mount base;
- a one-piece hold member provided inside of the deck separated downward from said mount member by a predetermined distance said one-piece hold member including a central portion having an aperture;
- a handle support shaft insertable through the respective apertures of said one-piece mount member and said one-piece hold member and supported by said hold member and said mount member;
- and
- a one-piece support collar provided within said one-piece mount member at a support position of said handle support shaft, for rotatably supporting said handle support shaft, and, said one-piece support collar including a spherical outer circumference adapted to the central spherical aperture of said one-piece mount member so as to fit along a common spherical contact surface and a cylindrical inner aperture adapted to the support position of said handle support shaft for absorbing a deviation of support positions of said handle support shaft.
