The impact force is likely to be concentrated on the flap base end portion in the vicinity of the point D where the ruled line forming 0A and the bent ruled line C intersect, and there is a risk of breakage and damage from this point.

Moreover, in this fixed shock absorber 100,
The other side surface (sleeve surface) orthogonal to the side surface 100D (connecting the top plate 100B and the bottom surface 100C) is open, and the edge portion of this opening portion is reinforced from the four upper, lower, left, and right sides. In order to fix the article 102 to be packed, an inwardly folded reinforcing flap 100E is separately provided.

In addition to the side surface 4 that is connected in the direction of movement), a cushioning flap 5 that protrudes in the X direction and has a notch portion 51 described below at its tip portion, and the end surface of this fixed cushioning device 1 (hereinafter referred to as the closing surface). And a flap 6 for closing, which is used to hold the (vib) 21 in a closed state, and in particular, absorbs or alleviates an impact force from the X direction.

When the shock absorbing flap 5 is housed inside the packing box 9 and an external shock force, especially from the X direction, acts, the shock force propagates from the packing box to the fixed shock absorber 1. This is to prevent or damage the object 10 to be packed inside the fixed shock absorber 1 by absorbing or mitigating as much as possible. For this reason, the cushioning flaps 5 extend from the top surface 2 and the floor surface 3, respectively, and project from the side surfaces 4 in parallel with each other by the same length. It is configured to contact the inner wall surface 92 of 9.

In particular, the cushioning flap 5 of this embodiment
Is a notched portion 51 which is formed by notching the tip portion into a substantially triangular shape.
As shown in FIG. 1 (B), the impact force is dispersed by dividing the portion in contact with the inner wall surface of the packaging box into a plurality of portions. In other words, this notch 51
Protects the impact force from being concentrated on a part of the cushioning flap 5, particularly on the base end portions 52 on both sides of the cushioning flap 5. In addition, the notch 5 of the flap 5
