5. The vehicle hood hinge structure according to claim 2 , wherein
the restraining member includes an extension part extending in a horizontal direction toward the first surface with the hood attachment part in the closed position relative to the body attachment part, the extension part being moved into contact with the first surface in response to the application of the prescribed force.
6. The vehicle hood hinge structure according to claim 5 , wherein
the hood attachment part includes a main body that extends in a forward direction from the hinge part along an inboard side of the body attachment part relative to the vehicle longitudinal direction, and the restraining member includes an extension part that extends in an outboard direction from the main body to a location outboard of a section of the body attachment part.
7. The vehicle hood hinge structure according to claim 6 , wherein
the extension part of the restraining member has a U-shape as viewed from above, the extension part having a first leg connected to the main body and a second leg that extends in an inboard direction toward the contact portion.
8. The vehicle hood hinge structure according to claim 2 , wherein
the first surface is a downwardly facing surface that engages the restraining member to limit upward movement of the hood attachment part upon the application of the prescribed force.
9. The vehicle hood hinge structure according to claim 8 , wherein
the restraining member includes an upward facing surface which engages the downward facing surface to limit upward movement of the hood attachment part upon the application of the prescribed rearward directed force.
10. The vehicle hood hinge structure according to claim 2 , wherein
the first surface is an upright and outboard facing surface that engages the restraining member to limit lateral movement of the hood attachment part in an inboard direction relative to the body attachment part upon the application of the prescribed force on the hood attachment part.
11. The vehicle hood hinge structure according to claim 10 , wherein
the contact portion includes a second surface that is a downwardly facing surface, and
the restraining member includes an upwardly facing surface that engages the downwardly facing surface to limit upward movement of the hood attachment part upon the application of the prescribed rearward directed force on the hood attachment part.
12. The vehicle hood hinge structure according to claim 2 , wherein
the contact portion defines an aperture in the body attachment part, and
the restraining member is spaced apart from the aperture and the first surface while the hood attachment part is in the closed position relative to the body attachment part, with the restraining member having a non-contacting relationship with the body attachment part while moving between the open position and the closed position.
13. The vehicle hood hinge structure according to claim 12 , wherein
the restraining member is moved into the aperture upon application of the prescribed force on the hood attachment part.
14. The vehicle hood hinge structure according to claim 12 , wherein
the body attachment part includes a main body, and
the restraining member includes an extension part that is located above a main body of the body attachment part while the hood attachment part is in the closed position.
15. The vehicle hood hinge structure according to claim 14 , wherein
the body attachment part has a forward end that is located at a third location that is forward from the second location while the hood is in the closed position relative to the vehicle longitudinal direction.
16. The vehicle hood hinge structure according to claim 15 , wherein
the body attachment part includes an upright section that extends upward from the main body, the contact portion defining an aperture in the upright section, the aperture being located rearward from the third location relative to the vehicle longitudinal direction.
17. The vehicle hood hinge structure according to claim 16 , wherein
the restraining member includes an extension part that extends outboard of the upright portion of the body attachment part with the hood attachment part in the closed position.
18. A vehicle body structure comprising:
a hood ledge that extends in a vehicle longitudinal direction;
a hinge including a body attachment part fixed to the hood ledge, a hood attachment part, and a hinge part connecting the body attachment part and the hood attachment part for movement between a hood closed position and a hood open position;
a hood fixed to the hood attachment part for movement between the hood closed position and the hood open position with respect to the hood ledge, the hood including a front edge, a rear edge, a first side edge and a second side edge, with the first side edge and the front edge defining a front corner and the first side edge and the rear edge defining a rear corner,
