Description

キャスク１が水平姿勢（詳細には、キャスク１の軸方向が水平方向となる姿勢）で落下した場合、その落下方向と第２緩衝体１０Ａの半径方向が一致する。そのため、仮に、緩衝部材１１の当接面１４を第２緩衝体１０の半径方向に沿うように形成すると、緩衝部材１１の当接面１４（外郭）を介して第１緩衝体９Ａに衝撃が直接伝達されてしまい、第１緩衝体９Ａへの衝撃加速度が大きくなる。これに対し、本実施形態では、緩衝部材１１の当接面１４を第２緩衝体１０の半径方向に対して傾斜するように形成するので、緩衝部材１１の当接面１４（外郭）が潰れやすく、第１緩衝体９Ａに衝撃が直接伝達されない。 When the cask 1 falls in a horizontal posture (specifically, the posture in which the axial direction of the cask 1 is the horizontal direction), the falling direction coincides with the radial direction of the second buffer body 10A. Therefore, if the contact surface 14 of the buffer member 1 1 to form along the radial direction of the second buffer body 10, a first buffer member 9A via the abutment surface 14 of the buffer member 1 1 (outer) The impact is directly transmitted and the impact acceleration to the first buffer 9A is increased. In contrast, in the present embodiment, since the formed so as to incline the abutment surface 14 of the buffer member 1 1 to the radial direction of the second buffer body 10, the abutment surface 14 of the buffer member 1 1 (outer) Is easily crushed, and the impact is not directly transmitted to the first buffer body 9A.

なお、上記第２の実施形態においては、位置決め機構として、緩衝部材１６の外周側に溝１８を形成し、その溝１８に紐状部材１７を挿通して紐状部材１７の位置決めを行う場合を例にとって説明したが、これに限られない。すなわち、例えば図７で示すように、緩衝部材１６の周方向の複数個所に金具１９を取付け、この金具１９に紐状部材１７を挿通して紐状部材１７の位置決めを行ってもよい。 Incidentally, in the second embodiment, as a positioning mechanism, if a groove 18 on the outer peripheral side of the cushioning member 1 6, the positioning of the string-shaped member 17 by inserting the string-shaped member 17 in the groove 18 However, the present invention is not limited to this. That is, for example, as shown in FIG. 7, metal members 19 may be attached to a plurality of locations in the circumferential direction of the buffer member 16 , and the string members 17 may be inserted into the metal members 19 to position the string members 17.
