To provide a propeller shaft fall prevention device which can absorb an impact load from a vehicle propeller shaft, and can suppress the interference of the vehicle propeller shaft with a vehicle body when the vehicle propeller shaft falls from the vehicle body.SOLUTION: A propeller shaft fall prevention device 14 includes: a support member 20 having a fixed part 20a fixed to a vehicle body 16, and a pair of longitudinal support parts 20b protruding downward of the vehicle body 16 from the fixed part 20a with a prescribed interval therebetween; and an annular main body member 30 which surrounds a propeller shaft 12 in a state of being supported to the pair of support parts 20b. The main body member 30 is fastened to the pair of support parts 20b so as to move in a longitudinal direction of the pair of support parts 20b when an impact load is applied to the main body member 30 from the propeller shaft 12.SELECTED DRAWING: Figure 1

    【課題】車両用プロペラシャフトが車体から脱落した場合に、車両用プロペラシャフトからの衝撃荷重を吸収するとともに、車両用プロペラシャフトと車体との干渉を抑制することができるプロペラシャフト脱落防止装置を提供する。【解決手段】プロペラシャフト脱落防止装置14によれば、車体16に固定された固定部20aおよび所定の間隔を隔てた状態で固定部20aから車体16の下方へ突き出す長手状の一対の支持部20bを有する支持部材20と、一対の支持部20bに支持された状態でプロペラシャフト12を囲む環状の本体部材30とを含んでいる。本体部材30は、本体部材30に対してプロペラシャフト12から衝撃荷重が加えられると一対の支持部20bの長手方向に移動するように、一対の支持部20bに締結されている。【選択図】図1
