Abstract
The impact absorption device includes an impact absorbing member and an auxiliary member. The impact absorbing member is attached to an installation surface of a base portion rotatably about a first pivoting axis extending in a first direction and is reversibly switched between a retracted state and a protruding state, and the auxiliary member is attached rotatably about a second pivoting axis and is reversibly switched between a retracted state and a protruding state. A height of the impact absorbing member from the base portion in the protruding state is higher than that of the auxiliary member. In the protruding state, at least a portion of the impact absorbing member and at least a portion of the auxiliary member face each other, and the impact absorbing member deforms when receiving a load including a component in a direction opposite to the base portion, thereby engaging with the auxiliary member.
