Further, the bearing portion 18 and the output shaft 13 are sealed with a sealing means (not shown) such as an O-ring to prevent water from entering from a surface other than the upper surface.

  As shown in FIGS. 4 and 5, the cover 17 is formed in a shape capable of covering the case 16 by providing a space 19 with the case 16, and is integrally formed by, for example, casting or the like. . The cover 17 is provided with a through hole 20 (see FIG. 2) at a position corresponding to the tap hole 25 formed on the base 4. The cover 17 is placed and fixed on the base 4 by inserting and tightening a screw (not shown) into the through hole 20. Here, air is accumulated in the storage box 9 due to water intrusion into the space below the upper surface of the case 16 (specifically, the upper end 24 surface of the side wall of the case 16 described later) in the space 19. By forming 21, water can be prevented from entering the case 16.

  Next, the structure which prevents the penetration | invasion of the water in the case 16 of the vehicle withdrawal prevention apparatus which concerns on this embodiment is demonstrated based on FIG. In the following description, water such as rainwater begins to accumulate around the vehicle exit prevention device, the water level around the cover 17 gradually increases (see FIG. 5), and the water level around the cover 17 is the upper surface of the cover 17. An example will be described in which the vehicle exit prevention device is flooded (see FIG. 6).

  First, water such as rainwater starts to accumulate around the vehicle exit prevention device shown in FIG. 1, and at the same time, the water gets over the base 4 and enters the space 19 between the cover 17 and the base 4 or from the insertion portion 22. start. Then, the water level of the water that has entered the space 19 gradually rises according to the water level of rainwater or the like around the cover 17. In this state, the pressure in the cover 17 is atmospheric pressure. Further, the intrusion of water from a surface other than the upper surface of the case 16 is prevented by the waterproof structure of the case 16 itself. Then, as shown in FIG. 5, the water level of the water that has entered the space 19 exceeds the upper end 23 of the insertion portion 22, and at the same time, in the storage box 9, the region inside the case 16 and the space 19 above the water level. An air pool 21 composed of a region is formed. Then, as shown in FIG. 6, when the water level around the cover 17 further rises, the air pool 21 is subjected to pressure according to the rise in the water level, and the air pool 21 is compressed and water in the cover 17 is compressed. As the water level rises, the pressure in the air pool 21 begins to rise. The water level in the cover 17 is maintained where the pressure in the air pool 21 and the pressure corresponding to the height difference between the water level around the cover 17 and the water level in the cover 17 are balanced. The In this way, the air reservoir 21 is formed so as to cover the upper portion of the case 16, and as shown in FIG. 6, for example, even when the vehicle exit prevention device is submerged, water flows into the case 16 from the upper surface of the case 16. Avoid intrusion.

  With such a configuration, the vehicle escape prevention device according to the present embodiment is configured to prevent the intrusion of water from a surface other than the upper surface while opening the upper surface, and is mounted and fixed on the base 4. The case 16 is covered by a cover 17 that houses the drive mechanism portion 8 and that is provided with a space 19 between the case 16 and is placed and fixed on the base 4, so that water can enter the case 16. This can be prevented by the air reservoir 21 formed inside. In this way, it is possible to prevent water from entering the drive mechanism unit 8 without providing a seal member that seals between the case 16 and the cover 17. Therefore, it is not necessary to perform complicated operations such as the installation work and application work of the seal member between the case and the cover, and the work of inspecting whether or not the seal member has been correctly installed. Work time can be shortened. In this way, it is possible to provide a vehicle exit prevention device that can easily prevent water from entering the drive mechanism unit 8.

  Further, in the above embodiment, the wiring of the cable such as a power cable and a communication cable to the drive mechanism unit 8 is omitted from illustration, but for example, from the outside of the case 16 at the lower part of the storage box 9 via the space 19. It is preferable to lay from the upper surface of the case 16. Thus, the cable laying operation can be easily performed using the space 19 provided between the case 16 and the cover 17. Conventionally, the cable is inserted into the case 16 by, for example, making a hole for wiring in the case 16, and a rubber seal member such as grommet is used to close the hole for the communication. However, in the case of the invention according to the present embodiment, as shown in FIG. 5, the upper surface 24 of the case 16 is covered with the air reservoir 21, so that a sealing member such as a grommet is not used. A cable can be laid in the case 16.

  In the present embodiment, the back surface of the cover 17 is described as being formed so as to be horizontal with respect to the ground as shown in FIG. 5 and the like, but although not illustrated, it faces the upper surface of the case 16. The inner surface of the cover 17 to be formed may be inclined in one direction. In this case, water droplets condensed on the back surface of the cover 17 after water has entered, etc. can flow in one direction, and water can be prevented from entering the case 16 more reliably.

  In the present embodiment, the upper end 24 of the case 16 is preferably formed as high as possible on the cover 17 side in consideration of wiring space such as a power cable and a communication cable. When the height in the cover 17 is the same, the higher the upper end 24 of the case 16 is, the higher the water level in the cover 17 can be allowed to rise. Therefore, even when the device is submerged deeply, the case 16 enters the case 16. Infiltration of water can be prevented.

  Further, in the present embodiment, the lock unit 2 has been described as standing between the front and rear tires of the parked vehicle that has entered to prevent unauthorized parking of the parked vehicle. You may stand up and prevent illegal leaving of a parked vehicle.
