Translation of "Bumper" in Japanese

The traffic was very heavy. The cars were lined up bumper to bumper.

交通渋滞で、車が数珠つなぎでした。

The car bumper absorbed some of the impact.

バンパーが衝撃をいくらか吸収してくれた。

But, a bumper for 1 million yen, against my 2.5 million yen savings

なのに250万円の内 ここで100万円のバンパーを

"Take a look at this." "Eh?" "There's an impact mark on the right-hand side of the bumper."

「これを見て」「え？」「バンパーの右側に衝突痕があるわ」
