Abstract

A steering apparatus of a hydrofoil includes first to fourth propulsion portions, a central connecting portion, a left hydrofoil, and a right hydrofoil. Among the first to fourth propulsion portions, the first propulsion portion 41 and the third propulsion portion are disposed on the left side, and the second propulsion portion and the fourth propulsion portion are disposed on the right side. The central connecting portion connects the first to fourth propulsion portions with each other via a first fixing portion and a second fixing portion. A left hydrofoil and a right hydrofoil are respectively attached to outer sides of the central connecting portion via the first fixing portion and the second fixing portion.

First claim

What is claimed is:

1. A steering apparatus of a hydrofoil, the steering apparatus comprising:
at least one propulsion component each on a left side and on a right side;
a central connecting structure that connects the propulsion portion components with each other;
a support structure that comprises a support block and a support pin; and
a fin attached to an outer side of the central connecting structure, wherein the central connecting structure comprises
a first central connecting structure and a second central connecting structure which are disposed vertically as two pieces,
wherein central portions of the first central connecting structure and the second central connecting structure in the left-right direction are supported in a state penetrating through an opening formed in the support block in the left-right direction, and
the support pin vertically penetrates a through hole formed in each of the central portions of the first central connecting structure and the second central connecting structure in the left-right direction and supports the central connecting structure at inside of the support block.

2. The steering apparatus of the hydrofoil according to claim 1 , further comprising:
a first fixing structure that fixes each left side of the first central connecting structure and the second central connecting structure, the first fixing structure being attached with the fin disposed on a left outer side; and
a second fixing structure that fixes each right side of the first central connecting structure and the second central connecting structure, the second fixing structure being attached with the fin disposed on a right outer side.

3. The steering apparatus of the hydrofoil according to claim 1 , wherein
each of the first central connecting structure and the second central connecting structure is formed in a flat plate shape.

4. The steering apparatus of the hydrofoil according to claim 1 , wherein
a space in which rotation is enabled, with the support pin as a center is set in the central connecting structure, restricts a rotatable range in which the central connecting structure rotates with the support pin as the center.

5. The steering apparatus of the hydrofoil according to claim 1 , wherein
a plurality of the propulsion components are provided next to each other in a vertical direction of the central connecting structure, and
the central connecting structure is twisted by an output difference in propulsion force of the propulsion components provided vertically.
