And a suspension tower (both not shown). A piston (not shown) is disposed inside the cylinder 24 so as to be slidable in the vertical direction of the vehicle 10. When the actuator 22 is operated, gas is supplied into the cylinder 24 below the piston. Thus, the piston in the cylinder 24 is raised by the internal pressure of the cylinder 24 that is raised by the supply of gas.

The actuator 22 includes a rod 26. The rod 26 is formed in a rod shape whose longitudinal direction is along the sliding direction of the piston in the cylinder 24, and the lower side of the middle portion in the longitudinal direction enters the inside of the cylinder 24 from the upper end of the cylinder 24. Further, the lower end portion of the rod 26 positioned in the cylinder 24 is integrally coupled to the piston in the cylinder 24. On the other hand, a pressing portion 28 is integrally formed with the rod 26 at the upper end portion in the longitudinal direction of the rod 26. It is attached. The pressing portion 28 is formed in a hemispherical shape whose upper surface is curved in a spherical shape. In the present embodiment, the curved surface of the pressing portion 28 forms the hood 30 in the initial state where the actuator 22 is not operating. The panel 32 is in contact with one surface (lower surface) in the thickness direction. In the present embodiment, the curved surface of the pressing portion 28 is in contact with the lower surface of the hood inner panel 32 in the initial state as described above, but the pressing portion 28 is separated from the hood inner panel 32 in the initial state. You may be the structure which is carrying out.

  The outer shape of the hood 30 is set so that the engine room 36 can be closed from above. In addition, the hood 30 is connected to a hood hinge (not shown) at both ends along the width direction of the vehicle 10 on the rear end side along the front-rear direction of the vehicle 10, and extends in the width direction of the vehicle 10 via the hood hinge.

  Further, a latch (not shown) provided on a member constituting the vehicle body on the front end side of the engine room 36 can be engaged with the front end side of the hood 30, and this latch engages with the hood 30. Thus, the rotation of the hood 30 around the shaft portion of the hood hinge, that is, the rotation of the hood 30 for opening the engine room 36 is restricted.

  A hood outer panel 38 that constitutes the hood 30 together with the hood inner panel 32 is disposed above the hood inner panel 32 that constitutes the hood 30. Inside the outer periphery of the hood 30, the hood inner panel 32 and the hood outer panel 38 are separated from each other in the thickness direction, but at the outer periphery of the hood 30 and in the vicinity thereof, the hood inner panel 32 and the hood outer panel 38 are separated from each other. The hood inner panel 32 and the hood outer panel 38 are integrated with each other by a hem portion 40 that is folded back so as to wrap around the outer peripheral portion of the hood inner panel 32 in the vicinity of the outer peripheral portion of the hood outer panel 38. Combined.

  Further, on the flat plate portion 16 of the cowl louver 14 described above, a shielding unit is configured as a front-rear direction shielding unit and a supporting unit is configured to face the hood 30 in the vertical direction of the vehicle 10 in front of the hem unit 40. A member 50 is provided. For example, the shielding member 50 formed of a relatively hard rubber material or a synthetic resin material having such elasticity as that of the rubber material as a whole has a flat base portion 52 as shown in FIGS. It has. The base 52 is integrally fixed to the flat plate portion 16 on the surface of the flat plate portion 16 on the side facing the hood 30 by fastening means such as bolts, rivets or clips, or adhesive means such as an adhesive. .

  An end portion of the base 52 on one side along the front-rear direction of the vehicle 10 (the rear side of the vehicle 10 in the present embodiment) is a bent portion 54, and the shielding member 50 has a hood 30 at the bent portion 54. Is bent around an axis whose axial direction is the width direction. A flat plate portion 56 is continuously formed from the bent portion 54. In the shielding member 50 bent at the bent portion 54, the side opposite to the bent portion 54 of the plate portion 56 faces the direction inclined upward of the vehicle 10 with respect to the direction opposite to the bent portion 54 of the base portion 52.

  An end portion of the plate portion 56 opposite to the bent portion 54 is a bent portion 58, and the shielding member 50 is bent around an axis whose axial direction is the width direction of the hood 30. . A flat plate portion 60 is continuously formed from the bent portion 58. In the shielding member 50 bent at the bent portion 58, the side opposite to the bent portion 58 of the plate portion 60 faces the direction inclined toward the bent portion 54 side of the base portion 52 toward the upper side of the vehicle 10. From the opposite side of the bent portion 58 of the plate portion 60, the bent portion 54, the plate portion 56, the bent portion 58, and the plate portion 60 are alternately formed, and the shielding member 50 is bent in a bellows shape as a whole. And folded.

  The end of the plate portion 60 farthest from the base 52 on the opposite side to the bent portion 58 is a bent portion 62, and the shielding member 50 is bent at the bent portion 62. A side of the shielding member 50 bent by the bent portion 62 opposite to the plate portion 60 is a connecting piece 64. The connecting piece 64 is formed in a flat plate shape whose longitudinal direction is along the width direction of the hood 30, and a seal substrate 66 is disposed on the surface of the connecting piece 64 facing the hood 30. The seal substrate 66 has a longitudinal direction along the width direction of the hood 30, and wall portions from both ends in the width direction of the seal substrate 66 along the longitudinal direction of the vehicle 10 toward the hood 30 (that is, upward). The cross-sectional shape that is erected and cut in the width direction (that is, the cross-sectional shape in the state shown in FIG. 1) is a concave shape that opens toward the hood 30.

  The seal substrate 66 is provided with a long seal member 68 formed of a rubber material or a synthetic resin material having elasticity similar to that of a rubber material. The portion of the seal member 68 opposite to the seal substrate 66 is in pressure contact with the hood inner panel 32 inside the hood 30 rather than the hem portion 40. The connecting piece 64 is provided with a plurality of clips 70. The clips 70 are intermittently arranged along the width direction of the hood 30, and each clip 70 penetrates the connecting piece 64, the seal substrate 66, and the hood inner panel 32 in the thickness direction of the hood inner panel 32. The seal substrate 66 and the seal member 68 are fastened and fixed to the hood inner panel 32 in a state where the seal member 68 is pressed against the hood inner panel 32.

<Operation and Effect of First Embodiment>
Next, the operation and effect of the present embodiment will be described.

  In the vehicle 10 to which the present embodiment is applied, for example, when load detection means such as a pressure sensor provided at the front end portion (for example, a bumper) of the vehicle 10 detects a load from the front side of the vehicle 10, The actuator 22 of the pop-up hood device 12 is operated. When the actuator 22 is operated, for example, gas is supplied from a gas generating means such as a gas generator to the cylinder 24, and the internal pressure of the cylinder 24 increases. When the internal pressure of the cylinder 24 increases and the piston in the cylinder 24 slides in the cylinder 24 so that the piston rises, the rod 26 extends from the cylinder 24.

  When the rod 26 extends from the cylinder 24, the pressing portion 28 provided at the tip of the rod 26 presses the pressing portion 28 of the hood 30 upward. In this way, the hood 30 pushed up by the pressing portion 28 has the hood 30 around an axis whose axial direction is the width direction of the vehicle 10 centering on the engagement portion with the latch (that is, the front end side of the hood 30). It rotates so that the rear-end side may rise (refer FIG.2 and FIG.4). As a result, the distance between the hood 30 and various devices and various members such as the engine in the engine room 36 increases.

  In this state, when any object falls on the hood 30 from above the hood 30, the hood 30 is lowered (that is, the engine room) by the distance from the various devices and various members such as the engine in the engine room 36. 36). Therefore, it is possible to absorb an impact when an object falls on the hood 30 due to such deformation of the hood 30.

  Further, when any object falls from above the hood 30, the object presses the hood 30 downward. The hood 30 that has received such downward pressing force tends to indirectly press and slide the piston in the cylinder 24 via the pressing portion 28 and the rod 26. Since the piston slides against the gas pressure in the cylinder 24 in this case, at least a part of the force with which the falling object presses the hood 30 is the resistance of the gas pressure. Absorbed. Therefore, this can also absorb an impact when the object falls on the hood 30.

  On the other hand, the seal member 68 and the seal substrate 66 are fixed to the hood inner panel 32 of the hood 30 by the clip 70, and the connecting piece 64 of the shielding member 50 is fixed to the seal substrate 66. Therefore, when the hood 30 is pressed by the pressing portion 28 as described above and rotated so that the rear end side of the hood 30 is raised, the connecting piece 64 is raised along with the hood inner panel 32. When the connecting piece 64 is lifted in this way, the shielding member 50 is deformed so that the bending angle of the shielding member 50 at the bent portion 54 or the bent portion 58 is changed, and the shielding is performed as shown in FIGS. Member 50 is deployed.

  In the state where the rear end side of the hood 30 is raised, the space between the flat plate portion 16 and the hood 30 is widened. However, as the hood 30 is raised, the shielding member 50 is deployed, so that the flat plate portion 16 and the hood 30 are During this period, the partitioned state is maintained. For this reason, when the rear end side of the hood 30 rises and the distance between the flat plate portion 16 and the hood 30 is widened, the rainwater, foreign matter, and the like enter the engine room 36 from the rear of the hood 30. The shielding member 50 interferes with such rainwater and foreign matter. For this reason, even if the actuator 22 is in the activated state, it is possible to prevent or effectively suppress intrusion of rainwater and foreign matters from the rear of the hood 30 into the engine room 36.

  Further, in the present embodiment, the shielding member 50 is made of a relatively hard rubber material or a synthetic resin material having elasticity comparable to such a rubber material. For this reason, if the rear end side of the hood 30 tries to bend by its own weight with the hood 30 closed in the engine room 36, for example, the elasticity of the shielding member 50 acts so as to resist this bending (that is, the hood 30). The shielding member 50 supports the hood 30 from below with such a support rigidity that can prevent or limit the bending of 30). For this reason, even if it is the structure which can raise the rear-end side of the hood 30 as mentioned above, it can prevent or suppress effectively that the rear-end side of the hood 30 bends below.

  Further, since the shielding member 50 has elasticity, it can be elastically deformed so that the connecting piece 64 approaches the base 52. Therefore, as described above, when any object collides with the hood 30 from above, the impact can be absorbed also by the elastic deformation of the shielding member 50 in the direction in which the connecting piece 64 approaches the base 52. In particular, even when an object collides with the hood 30 from above without satisfying the operating conditions of the actuator 22, the impact of the collision can be reduced as described above, so that the deformation of the hood 30 can be prevented or effectively performed. Can be suppressed.

<Configuration of Second Embodiment>
Next, other embodiments of the present invention will be described. In describing each of the following embodiments, the same parts as those in the previous embodiment are basically the same as those in the embodiment described above including the first embodiment. Reference numerals are assigned and detailed description thereof is omitted.

  FIG. 5 is a perspective view corresponding to FIG. 3 showing a shielding member 102 constituting a shielding means as a front-rear direction shielding means which is a configuration of a main part of the second embodiment of the present invention. As shown in this figure, the shielding member 102 is not formed in a bellows shape by a relatively hard rubber material such as the shielding member 50 or a synthetic resin material having such elasticity as that of the rubber material. Is formed by a sheet material having such a size that it can be deployed between the flat plate portion 16 and the rear end side of the hood 30 in a state where the rear end side of the hood 30 is turned up.

  The sheet material constituting the shielding member 102 is flexible, and the shielding member 102 is appropriately bent while the hood 30 is closing the engine room 36. The end of the shielding member 102 on the flat plate portion 16 side is fixed to the flat plate portion 16 by bonding means such as an adhesive or heat welding, or fastening means such as bolts, rivets, or clips. On the other hand, the vicinity of the end of the shielding member 102 on the hood inner panel 32 side is fixed to the connecting piece 64 in the same manner as the shielding member 50.

<Operation and Effect of Second Embodiment>
Even in this embodiment, when the actuator 22 is activated and the hood 30 is raised, the shielding member 102 is deployed between the rear end side of the hood 30 and the flat plate portion 16. Therefore, in the same manner as in the first embodiment, it is possible to prevent or suppress the entry of rainwater or foreign matter into the engine room 36.

  In the configuration of the present embodiment, since the shielding member 102 has a flexible sheet shape, unlike the shielding member 50, it does not have a function of supporting the rear end side of the hood 30 from below. Therefore, the support means includes a support body such as a rubber block that supports the width direction intermediate portion of the hood 30 from below on the flat plate portion 16 and an urging means that urges the hood 30 such as a compression coil spring upward from the lower side. It is preferable to provide as.

  Although not particularly illustrated, the shielding member 50 according to the first embodiment is intermittently provided along the width direction of the hood 30 and the shielding member 102 is disposed between the shielding members 50 and the like. However, the shielding member 50 may be used as the support means.

<Configuration of Third Embodiment>
Next, a third embodiment of the present invention will be described.

  FIG. 6 is a perspective view corresponding to FIG. 3 showing the configuration of the main part of the present embodiment. As shown in this figure, in this embodiment, in addition to the shielding member 50 as the front-rear direction shielding means, the shielding members 152 constituting the shielding means as the width direction shielding means are located in the vicinity of both ends in the width direction of the hood 30. Is provided. Although not shown in detail, the shielding member 152 has a hood inner panel 32 whose upper end constitutes the hood 30 by an adhesive means such as an adhesive, heat welding, or a fastening means such as a bolt, a rivet, or a clip. It is fixed to the hood inner panel 32 in the vicinity of the end in the width direction. On the other hand, the lower end of the shielding member 152 is attached to the vehicle body on both sides in the width direction of the engine room 36 such as a cowl side upper member by an adhesive means such as an adhesive or heat welding, or a fastening means such as a bolt, a rivet, or a clip. It is fixed to the constituent members.

  The shielding member 152 may be fixed to the hood inner panel 32 of the hood 30 by the clip 70 similarly to the shielding member 50.

  The shielding member 152 is formed of a flexible sheet member similar to the shielding member 102, and the hood 30 is rotated so that the actuator 22 operates and the rear end side of the hood 30 is raised. The size of the hood 30 is set so as not to hinder the rotation of the hood 30 in any state in which the hood 30 is rotated so that the front end side of the hood 30 rises around the shaft member of the hood hinge.

<Operation and Effect of Third Embodiment>
In this embodiment, when the hood 30 is rotated so that the actuator 22 operates and the rear end side of the hood 30 is raised, the shielding member 50 is only deployed between the flat plate portion 16 and the hood 30. First, the shielding member 152 is deployed between the vicinity of both ends in the width direction of the hood 30 and members such as cowl side upper members positioned on both sides of the engine room 36 in the width direction. For this reason, it is possible to prevent or suppress not only rainwater and foreign matter from the rear side of the hood 30 but also rainwater and foreign matter from both sides in the width direction of the hood 30 from entering the engine room 36.

  In the present embodiment and the second embodiment, since the shielding member 102 and the shielding member 152 are in the form of a flexible sheet, the hood 30 bends appropriately when the engine room 36 is closed. For example, when the hood 30 is rotated around the shaft member of the hood hinge and the engine room 36 is opened, the appearance may not be good. In consideration of such appearance, storage means such as a winding device that winds and stores the shielding member 102 or the shielding member 152 in a state where the hood 30 closes the engine room 36 may be provided.

  In the present embodiment, the shielding member 50 and the shielding member 152 are provided. However, it goes without saying that the shielding member 102 and the shielding member 152 may be provided. Moreover, the structure which provides only the shielding member 152, without providing the shielding member 50 and the shielding member 102 may be sufficient.

  Furthermore, although each said embodiment demonstrated on the assumption that the pop-up hood apparatus 12 for vehicles was provided, if it carries out from the viewpoint of this invention as described in each of Claim 1 to Claim 6 of a claim, The vehicle pop-up hood device 12 may not be provided (that is, the shielding means such as the shielding member 50, the shielding member 102, and the shielding member 152 may not be a part of the configuration of the vehicle pop-up hood device 12). .

  That is, as described above, when the hood 30 is rotated so that the front end side of the hood 30 rises around the shaft member of the hood hinge (that is, the hood 30 is rotated to open the engine room 36). In some cases, the rear end side of the hood 30 and the flat plate portion 16 may be opened, although not as much as the state in which the actuator 22 is activated. Therefore, even if the vehicle pop-up hood device 12 is not provided, providing the shielding means is extremely effective from the viewpoint of preventing or suppressing the entry of rainwater and foreign matter into the engine room 36.
