A movable trailing edge is composed of a main body including a structural frame member in which a spar and a rib intersect with each other, and a first outer plate that covers the main body. The first outer plate is placed on and cover the structural frame member, a rotating probe is pressed against the first outer plate from the obverse side thereof to friction stir weld the first outer plate and the side end face of the structural frame member. Joint parts are arranged in a dotted pattern.

What is claimed is: 1. A hollow assembly structure comprising: a structural frame member including at least one first plate and at least one second plate, the first plate and the second plate being arranged so that plate faces thereof intersect each other for keeping positions of the first plate and the second plate by each other; an outer plate that covers the structural frame member, wherein a side end face of the first plate or the second plate of the structural frame member is overlaid with the outer plate such that any abutting edges of said outer plate do not overlie said first and second plates; and at least one of a friction stir weld and friction pressure weld joining, without a stud, the outer plate to the first plate or the second plate, the weld comprising cooled and solidified material undergoing plastic flow extending from an obverse side of the outer plate to a part of the first plate or the second plate at an overlapped portion; wherein, the hollow assembly structure composes at least a part of a wing, and the first plate is a spar, the second plate is a rib, and the outer plate is a blade face, the structural frame member being formed by shaving out a block member, and the first plate and the second plate being formed integrally. 2. The hollow assembly structure of claim 1, wherein the outer plate is friction stir welded or friction pressure welded to the side end face of the first plate or the second plate so as to cover one side of the structural frame member, an additional outer plate is provided which covers another side of the structural frame member, and the structural frame member and the additional outer plate are formed by shaving out the block member so as to be integral. 3. The hollow assembly structure of claim 1, wherein joint parts of the structural frame member and the outer plate are arranged in the outer plate in a dotted pattern. 4. The hollow assembly structure of claim 2, wherein joint parts of the structural frame member and the outer plate are arranged in the outer plate linearly. 5. The hollow assembly structure of claim 1, wherein joint parts of the structural frame member and the outer plate are arranged in the outer plate in a dotted pattern. 6. The hollow assembly structure of claim 1, wherein joint parts of the structural frame member and the outer plate are arranged in the outer plate in a dotted pattern. 7. The hollow assembly structure of claim 1, wherein joint parts of the structural frame member and the outer plate are arranged in the outer plate linearly. 8. The hollow assembly structure of claim 1, wherein joint parts of the structural frame member and the outer plate are arranged in the outer plate linearly. 9. A movable trailing edge for an aircraft comprising: a main body of a box shape having an opening formed by shaving and of which an outer face serves as one of a blade face, a spar or a rib being integrally formed inside of the main body; and an outer plate which covers the opening of the main body of which an obverse face serves as another blade face, wherein a side end face of the spar or the rib of the main body is overlaid with the outer plate; and at least one of a friction stir weld and friction pressure weld joining, without a stud, the outer plate to the spar or the rib, the weld comprising cooled and solidified material undergoing plastic flow extending from an obverse side of the outer plate to a part of the spar or the rib at an overlapped portion.
