Title:
RELATIVE DISPLACEMENT INHIBITION STRUCTURE
Document Type and Number:
Japanese Patent JP2022142495
Kind Code:
A
Abstract:
To inhibit residual deformation in an oil damper with a fail safe function.SOLUTION: A relative displacement inhibition structure (1) includes an intermediate member (30) provided between a first structure (110) and a second structure (120), and inhibits the first structure (110) and the second structure (120) from being displaced relative to each other in a predetermined direction by external force. The relative displacement includes first displacement at an initial stage and second displacement after the first displacement. The relative displacement inhibition structure (1) has: a first displacement inhibition damping mechanism (10) provided between the first structure (110) and the intermediate member (30) and having a first displacement inhibition damping force for inhibiting the first displacement; a second displacement inhibition damping mechanism (20) provided between the intermediate member (30) and the second structure (120) and having a second displacement inhibition damping force for inhibiting the second displacement; and a restoration mechanism (40) provided between the intermediate member (30) and the second structure (120) and having a restoring force for restoring the second displacement inhibition damping mechanism (20) to an original point before the second displacement.SELECTED DRAWING: Figure 1
