Further, a first outer flange is protruded from the periphery of the upper opening end to form an upper opening-shaped storage body made of an antistatic member, and the left and right lower ends of the upper wall part having a vertical concave cross-sectional shape are formed. Left and right side walls with a quarter-circular cross section are vertically installed on the edge, the front and rear openings are each covered with vertical walls, and a second outer flange is provided protruding from the periphery of the upper opening to prevent static electricity. A lid portion with an upward opening is formed from a member, and the left side wall corresponding portion of the first outer flange portion is swingably connected to the left side wall corresponding portion of the second outer flange portion, so that the lid portion can be opened and opened. A packaging structure for a brushless motor that is foldable, wherein lower circumferential grooves into which the flanges of the brushless motor fit are arranged opposite to each other on the inner surfaces of the left and right side walls of the storage body at a predetermined length along the longitudinal direction. A plurality of upper circumferential grooves are provided at a predetermined pitch in the longitudinal direction, and a plurality of upper circumferential grooves are provided on the inner surface of the left and right side walls of the lid, into which the collar of the brushless motor that fits into the lower circumferential groove is fitted. Furthermore, a plurality of protrusions are arranged at predetermined pitches in the longitudinal direction on the right side wall corresponding part of the first outer flange of the storage body, and the right side wall corresponding part of the second outer flange of the lid part is provided. A plurality of recesses into which the protrusions fit are arranged at predetermined pitches in the longitudinal direction, and when a plurality of recesses are stacked in a staggered manner so that the left and right side walls are in contact with each other, the recesses in the lower row are adjacent to each other. The first flange of one of the upper storage main bodies interposed between the two lids rests on the upper surfaces of the upper walls of the two lower lids, and The lower surfaces of the bottom wall portions of the two storage main body portions are configured to abut against the second outer flange portion of the lower lid portion in a resting manner.
