- the second portion 10b which is made of the same material as the first portion 10a, may be coated with a material having a high friction coefficient to increase the frictional force and increase the diameter.
- the position and range where the second portion 10b is provided are determined according to the use of the aircraft 100. For example, as shown in FIGS. 19 to 25, an aircraft 100 that delivers home goods lowers a load 11 (cargo) connected to the suspension member 10, and the port grips the suspension member 10 to unload the cargo. In a supporting scheme, the second portion 10b of the suspension member 10 that the port grips is limited to the vicinity of the load.

- the configuration of the restriction member 32 may be combined with a configuration that restricts the movement of the suspension member 10 by directly gripping it. A first step of restricting the movement may be performed, and then a second step by the restricting member 32, which restricts the movement by directly gripping the second portion 10b of the suspension member 10, may precisely restrict the movement.
- the restricting member 32 shown in FIGS. 3 and 4 has a ring lock shape, and restricts the position of the suspending member 10 by rotating the bolt when the suspending member 10 enters a predetermined position.
- the restriction members 32 shown in FIG. 5 are stored with their tips facing the +Y direction when not in use, and rotate inward when the suspension member 10 enters a predetermined position, thereby 10 position limits are applied. Further, when the restricting member 32 grips the suspension member 10 as shown in FIGS. 6 to 8, movement in all of the X, Y, and Z directions can be restricted.
- the limiting member 32 may simply be a gripping portion that grips the second portion 10b of the suspension member 10, but for example, it may be a roller portion of a hoisting device. After the suspension member 10 enters, the roller portion rotates around the rotation shaft 34 to enable the descent. Also, by reversing the direction of rotation, it is possible to ascend.
- the suspension member 10 is positioned within a predetermined range (here, the range assumed to be affected by the rotation of the roller portion rotated to the position shown in FIG. 8).
- the guide portion 31 and the restricting member 32 rotate, and after the second portion 10b of the suspension member 10 is sandwiched between them, the roller portion rotates to enable elevation.
- the restricting member 32 only needs to have the effect of restricting the amount of movement of the suspension member 10, and the restricting method is not limited to the above example.
- the position limiting device 30 includes a roller portion of a hoisting device as the limiting member 32
