6. The vehicle according to claim 1 , wherein the embossed surface is formed such that the one direction is maintained in a state of being raised rearward relative to the front-rear direction of the vehicle body even when a posture of the vehicle body is changed during traveling.

7. The vehicle according to claim 2 , wherein the embossed surface is formed such that the one direction is maintained in a state of being raised rearward relative to the front-rear direction of the vehicle body even when a posture of the vehicle body is changed during traveling.

8. The vehicle according to claim 3 , wherein the embossed surface is formed such that the one direction is maintained in a state of being raised rearward relative to the front-rear direction of the vehicle body even when a posture of the vehicle body is changed during traveling.

9. The vehicle according to claim 4 , wherein the embossed surface is formed such that the one direction is maintained in a state of being raised rearward relative to the front-rear direction of the vehicle body even when a posture of the vehicle body is changed during traveling.

10. The vehicle according to claim 5 , wherein the embossed surface is formed such that the one direction is maintained in a state of being raised rearward relative to the front-rear direction of the vehicle body even when a posture of the vehicle body is changed during traveling.

11. A front bumper member to be provided at a lower portion of a front surface of a vehicle body of a vehicle, the front bumper member comprising:

an embossed surface formed on a surface of a side surface portion of the front bumper member,

wherein the embossed surface includes a directional pattern for assisting an airflow to direct in one direction along the surface,

wherein the embossed surface is formed such that the one direction is raised rearward relative to a front-rear direction of the vehicle body.

12. The front bumper member according to claim 11 , wherein the embossed surface includes protruding portions that protrude from a base surface,

wherein the protruding portions includes elongated protrusions each having an elongated shape,

wherein the elongated protrusions respectively have short-sides and long-sides, the short-sides of the elongated protrusions direct in a first direction, and the long-sides of the elongated protrusions direct in a second direction,

wherein a first recessed portion that linearly extend along the second direction is formed between first ones of the elongated protrusions, the first ones of the elongated protrusions being adjacent each other in the first direction, and

wherein the first recessed portions linearly extend at an angle raised rearward relative to the front-rear direction of the vehicle body.

13. The front bumper member according to claim 12 , wherein second recessed portions are formed between second ones of the elongated protrusions, the second ones of the elongated protrusions being adjacent each other in the second direction, and

one of the second recessed portions is shifted with respect to another one of the second recessed portions in the second direction.

14. The front bumper member according to claim 12 , wherein the second recessed portions are formed in a pattern in which the second recessed portions are bent in the first direction.

15. The front bumper member according to claim 13 , wherein the second recessed portions are formed in a pattern in which the second recessed portions are bent in the first direction.

16. The front bumper member according to claim 11 , wherein the embossed surface is formed such that the one direction is maintained in a state of being raised rearward relative to the front-rear direction of the vehicle body even when a posture of the vehicle body is changed during traveling.

17. The front bumper member according to claim 12 , wherein the embossed surface is formed such that the one direction is maintained in a state of being raised rearward relative to the front-rear direction of the vehicle body even when a posture of the vehicle body is changed during traveling.
