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.

Abstract: A frame joint structure includes a connecting member positioned adjacent to a joint between a first frame and a second frame. The connecting member has a first joint surface that abuts only one flat surface of the first frame, and a second joint surface that is integrally continuous with the first joint surface and abuts only one flat surface of the second frame. The connecting member is joined to the first frame and the second frame by a first joining member (such as adhesive).

Abstract: Provided is an article receiving device that allows an article to be put into and taken out of an article receiving portion without causing any undue burden on the body of the user. The article receiving device (30) for receiving an article (200) therein, comprises a receiving portion (48) having an opening (60) for passing the article into and out of the receiving portion, and a lid (70) rotatable around an axial line extending horizontally along a lower part of the opening to selectively open and close the opening, wherein the lid is provided with a lid side guide portion (98) extending across the axial line and toward a side of the receiving portion with respect to a rotational direction of the lid around the axial line.

Abstract: The present invention provides an aquatic moving body configured to move in a state where a main body portion is floated above a water surface, comprising: a first hydrofoil and a second hydrofoil disposed along a left-and-right direction of the aquatic moving body and provided in the main body portion so as to be able to change elevation angles independently of each other; a first propulsion unit provided at an end portion of the first hydrofoil and configured to generate a propulsive force; and a second propulsion unit provided at an end portion of the second hydrofoil and configured to generate a propulsive force, wherein a first partition wall is provided between the first hydrofoil and the first propulsion unit, and a second partition wall is provided between the second hydrofoil and the second propulsion unit.
