To provide a frame for a multicopter that corresponds to not only a load, but also stress generated during flight, take-off and landing, and further, is high in degree-of-freedom of design of a component installation part, with a small number of components.SOLUTION: Four arm parts having a mount part provided on one end and a connection part connected to the other end are arranged so that the mount part projects outward, and are connected to each other by the connection part at a middle part of each arm part, thereby forming a frame. A length of an outside projection part of each arm part is so set to be longer than 1/2 of a length of the arm part. The length of the arm part, the outside projection part and the middle parts of the arm parts to be connected are determined by the following relation: the length of the arm and two sides of the outside projection part of the arm part to be connected that is connected by the connection part of the arm part become two sides with a right angle therebetween, and become a right-angled triangle with an adjacent wheel distance of a rotary wing installed on both arm parts as a hypotenuse, and the middle part of the arm part becomes a point at which central axes of two arm parts concerning connection cross each other at a right angle.SELECTED DRAWING: Figure 1

    【課題】 荷重だけでなく飛行時や離着陸時に発生する応力にも対応し、部品搭載部の設計の自由度も高いマルチコプター用フレームを、少ない部品点数で提供する。【解決手段】一端にマウント部を備え、他端に連結部が接続された4本のアーム部を、マウント部が外側に突出するように配置し、各アーム部の中途部において、連結部により相互に連結してフレームを構成する。各アーム部の外側突出部の長さは、アーム部の長さの1/2より長く設定される。アーム部の長さ、外側突出部、および連結がなされるアーム部の中途部は、以下のような関係により決定することができる。アーム部の長さと、当該アーム部の連結部により連結された被連結アーム部の外側突出部の2辺は直角を挟む2辺となり、両アーム部に設置された回転翼の隣接軸距を斜辺とする直角三角形となる。また、アーム部の中途部は、連結に係る2本のアーム部の中心軸が直角に交差する点となる。【選択図】図1
