Title:
VEHICULAR AIR RESISTANCE REDUCING DEVICE
Document Type and Number:
Japanese Patent JP2019155978
Kind Code:
A
Abstract:
To suppress a load applied to an intake system of a vehicle, and to transition from an expanded state to a predetermined contracted state within a short time.SOLUTION: A rectifying body 21 includes a plurality of bag portions 24, and a seat portion 25. A base end edge 22 of the rectifying body 21 is placed along a circumferential edge of a rear surface of a vehicle, and is fastened to the vehicle. Each of the plurality of bag portions 24 includes: a bag body 26 in a tube-like shape; and an elastic body 27 in a spiral shape normally. When the bag body 26 in a contracted state expands against the spring force by the elastic body 27 from the base end edge 22 side toward a tip edge 23 side due to air intake in the bag body 26, the elastic body 27 is elongated from the spiral shape toward a rear side of the vehicle, and thus the rectifying body 21 becomes an expanded state. When the internal pressure of the bag body 26 in the expanded state is released to the air, the elastic body 27 returns to the spiral shape, and the rectifying body 21 is wound along with the return of the elastic body 27, and becomes the contracted state.SELECTED DRAWING: Figure 5
