  • the fully-closed state as illustrated in FIG. 3( c ) is provided for reducing air resistance by preventing travelling wind from being introduced to the inside during high speed travelling and the like.
  • the fully-closed state denotes a state in which air is prevented from being introduced to the inside of the shutter device 10 from the front side.
  • the shutter valve 11 is in a state of being vertical.
  • air resistance reduction provides an advantage to improve fuel efficiency.
  • the movement of the shutter valves 11 is controlled by the actuator 12 rotating the lever 14 a.
  • the shutter valve 11 is moved in the closing direction by wind pressure of travelling wind and in the opening direction by the biasing means. Basically, travelling wind inflows from the front of the automobile. However, depending on location of the shutter device 10 , there may be a case of inflowing from a position other than the front.
  • the opening is required to be fully-open or at least at the predetermined opening to prevent occurrence of overheating.
  • the present invention includes the biasing means which causes movement of returning from the fully-closed state to the predetermined opening state.
  • FIG. 4 is an explanatory view for attaching a return spring which is an example of the biasing means.
  • a return spring 13 is arranged between the rotating shaft 16 of the shutter valve 11 and the lever 14 a as the biasing means.
  • the lever 14 a includes a space 14 c which is capable of accommodating the return spring 13 .
  • the return spring 13 biases the lever 14 a in a direction to open the shutter valve 11 .
  • the return spring 14 a being the biasing means is not necessarily arranged at the lever 14 a which is connected to the actuator 12 .
  • the shutter valves 11 are interlocked. Therefore, it is not particularly required to limit where the return spring 14 a is arranged. Naturally, it is possible to arrange at a plurality of positions.
  • FIGS. 5( a ) to 5 ( c ) are explanatory views for operational directions of forces; FIG. 5( a ) illustrates a fully-open state, FIG. 5( b ) illustrates a predetermined opening state, and FIG. 5( c ) illustrates a fully-closed state.
  • a relative rotation range of the lever 14 a against the rotating shaft 16 is limited by the stopper 16 b arranged at the rotating shaft 16 .
  • the stopper 16 b has a C-shape obtained by eliminating a part of a cylindrical rib and accommodates the lever 14 a whose width is smaller than a width of an opening portion of the C-shape.
  • the return spring 13 being the biasing means biases the shutter valve 11 in the direction to be opened.
  • the relative rotation can be performed only by the amount of a gap s formed between the stopper 16 b and the lever 14 a.
  • a rotational force A is exerted from the actuator to the lever 14 a.
  • the shutter valve 11 when the shutter valve 11 is to be closed, transmission of the force is performed by the lever 14 a being contacted to the stopper 16 b.
  • a biasing force F of the return spring 13 is exerted, transmission of the force from the lever 14 a to the stopper 16 b is performed via the return spring 13 .
  • the rotation is performed without changing a relative positional relation as maintaining the gap s between the lever 14 a and the rotating shaft 16 .
  • movement of the shutter valve 11 is determined by a balance between travelling wind W and the biasing force F. That is, when the travelling wind W becomes larger than the biasing force F, the shutter valve 11 is rotated toward the fully-closed state. When the travelling wind W becomes smaller than the biasing force F, the shutter valve 11 is rotated toward the predetermined opening state. At that time, the lever 14 a and the rotating shaft 16 are relatively rotated. Here, it is also possible that the lever 14 a in the fully-closed state is contacted to the stopper 16 b at the opposite side to the side in the predetermined opening state.
  • the predetermined opening can be ensured without being maintained at the fully-closed state even when the actuator fails. Accordingly, it is possible to avoid at least overheating, while producing effects such as air resistance reduction during high speed operation and warming-up acceleration at engine operation. Further, since movement of the actuator is limited between the fully-open state and the predetermined opening state, the actuator can be downsized and the device can be also downsized as a whole. In addition, since the movement of the actuator can be small, it is possible to produce an effect to suppress power consumption.
