DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter with reference to FIGS illustrating in detail an embodiment of the present invention. However, unless otherwise specified, the dimensions, materials, shapes, relative arrangements, and the like of the components described in this embodiment are not intended to limit the scope of the present invention thereto, but are merely illustrative examples. It's just

FIGS. 1 and 2 show a mold forming body 10 corresponding to a supporting jig for fixing a transmission T / M1 (supporting object) at a predetermined position of an engine. As shown in FIG. A particle group 14 housed in a mesh inner bag 13 is loaded in a rectangular flat airtight outer bag 12 having a suction part 11. And the particle group 14
For example, it is formed of styrofoam particles of about 3 to 5 mm,
The packing density is determined as appropriate.
3 is 100 × 40 × 30 cm, 320
g, specifically 2-3 kgf / m3.

The inner bag 13 is formed of a fine nylon mesh from which the styrofoam particles do not fall off. To secure the thickness, as shown in FIG.
Square piece × 2, 100 × 30 cm square piece × 2, 30 ×
Square pieces 13a to 13c of 6 sides of 40cm square pieces x 2
Are prepared, and these edges are joined to form a rectangular bag.
In this case, the joining means may be heat fusion or stitching. However, since the weight load of the T / M1 is large, it is preferable that the heat fusion is performed and then the joining is performed by the seam 131 using a glove or the like.

The outer bag 12 is made of a so-called nylon tarpaulin, which is a fiber-reinforced resin cloth coated with nylon on both sides of the fiber cloth.
mm. Then, the outer bag 12 is folded in two and its edges are heat-sealed. At this time, since the outer bag 12 has the strength secured by the inner bag 13, it is not always necessary to reinforce it by sewing.

The outer bag 12 is preferably set to be larger than the size of the inner bag 13 with a margin around the outer bag 12 so that the outer bag 12 expands in accordance with the thickness of the inner bag 13. The male side 121a and the female side 121b of the velcro are attached near each side so as to prevent wrinkles from being formed on the sides due to the contraction due to the suction and to form an oil pool.

Further, the male and female Velcro is attached to the outer bag 12.
The suction part 11 attached to the three sides of the above and the other side is constituted by an intake valve provided with a check valve (not shown) for preventing a backflow of air at the time of suction. . On the other hand, a penetration hole 16 for penetrating a magic tape belt 15 for fixing to the support table 21 is provided on the back surface of the outer bag 12.
