Therefore, the sheet material 11 is housed in the rear space SP1 of the inner cover 31, that is, the space between the inner cover 31 and the holder 22. Note that FIG. 9A corresponds to the operation when the rear door 4 is opened, and FIG. 9B corresponds to the operation when the rear door 4 is closed. In FIG. 9B, the illustration of the spring 33 is omitted for convenience.

As shown in FIG. 9A, when the rear door 4 is opened, the surface cover 34 is urged forward by the spring 33, and the space SP0 is created between the inner cover 31 (plate portion 311) and the surface cover 34 (plate portion 341). It is formed. Therefore, the passage PA (FIG. 2) from the rear space SP1 of the inner cover 31 (plate portion 311) to the front space (SP2) of the surface cover 34 (plate portion 341) via the slit holes 318, 344 and the slit holes 318, 342a. 7A) is released.

As a result, air flows through the passage PA as shown by the arrow in FIG. 9A, and the scent of the fragrance of the sheet material 11 can be efficiently diffused toward the front space SP2 which is the opening of the rear door 4. Therefore, the occupant feels the fragrance when getting on and off the vehicle 1, and the comfort of the occupant is improved. In particular, since an air flow is generated around the rear door 4 as the rear door 4 is opened, it is easy to generate an air flow that passes through the sheet material 11, and the effect of diffusing the scent is high.

In the present embodiment, the slit holes 318 of the inner cover 31 and the slit holes 344 of the surface cover 34 are formed so as to be displaced from each other in the vertical direction. Therefore, it is possible to prevent dust, raindrops, and the like from entering the rear space SP1 from the front space SP2 when the rear door 4 is opened, and it is possible to suppress deterioration of the drug unit 10. In the surface cover 34, not only the slit holes 344 are formed on the front surface but also the slit holes 342a are formed on the left and right side surfaces, so that the scent is diffused over a wide range around the drug unit 10 when the rear door 4 is opened. Can be done. Since the slit holes 344 and the slit holes 342a are formed so as to be displaced from each other in the vertical direction, the slit holes 344 and 342a are continuously formed over the entire length of the surface cover 43 in the vertical direction, and the scent is formed around the slit holes 344 and 342a. Can be spread well.

As shown in FIG. 9B, when the rear door 4 is closed, the surface cover 34 comes into contact with the sealing material 32, and the convex portion 343 of the surface cover 34 is inserted into the slit hole 318 of the inner cover 31 and the first convex portion of the inner cover 31. The 316 fits into the slit hole 344 of the surface cover 34, respectively. As a result, the passage PA (FIG. 7A) communicating the rear space SP1 of the inner cover 31 and the front space of the surface cover 34 is blocked, and the sheet material 11 is arranged in the sealed rear space SP1. Therefore, the volatilization of the fragrance can be suppressed, and the effect of the fragrance can be continuously exerted when the rear door 4 is opened. Further, since the chemical unit 10 is sealed when the rear door 4 is closed, it is possible to prevent foreign substances such as dust and water droplets from being mixed into the chemical unit 10, and a stable fragrance effect can be obtained when the rear door 4 is opened. Be done.

When the sheet material 11 dries due to the diffusion of the scent from the drug unit 10 and the effect of the scent is reduced, the occupant removes the cover portion 30 while the base portion 20 of the drug unit 10 is adhered to the rear door 4, and the drug is used. Disassemble the unit 10. As a result, the sheet material 11 can be replaced, and the drug unit 10 can be used continuously. The occupant can easily remove the cover portion 30 by operating the side wall 314 of the inner cover 31 so as to spread it outward in the left-right direction, whereby the seat material 11 can be easily attached / detached or replaced.

According to this embodiment, the following effects can be obtained.
(1) The drug unit 10 has a pair of facing surfaces on the vehicle body frame 2 side and the rear door 4 side facing each other when the rear door 4 provided on the vehicle body frame 2 is closed, that is, the rear end surface 5a of the center pillar 5 and the front end of the rear door 4. It is provided in the gap CL between the surface 4a and the surface 4a (FIG. 3). The drug unit 10 includes a case for accommodating a sheet material 11 impregnated with a volatile agent (fragrance), that is, a base portion 20 and a cover portion 30 (FIGS. 4 and 5). The medicine unit 10 (base portion 20, cover portion 30) is substantially flat so as to be arranged in the gap CL between the rear end surface 5a of the center pillar 5 and the front end surface 4a of the rear door 4 when the rear door 4 is closed. (Fig. 4). The base portion 20 has a rear adhesive surface 212 attached to the front end surface 4a of the rear door 4 (FIG. 6).

As a result, the drug unit 10 having a simple structure can effectively generate fragrance in the vicinity of the door opening as the rear door 4 is opened. That is, the drug unit 10 can be easily retrofitted to the vehicle 1 without configuring the vehicle 1 so as to separately provide a space for mounting the drug unit 10. Further, when the rear door 4 is closed, the sheet material 11 can be sealed, whereby the volatilization of the fragrance is suppressed, and the effect of fragrance can be exhibited for a long period of time.

(2) The drug unit 10 further includes a cushion material 15 attached to the rear end surface 5a of the center pillar 5 so as to press the cover portion 30 when the rear door 4 is closed (FIG. 3). As a result, regardless of the variation in the gap CL between the rear door 4 and the center pillar 5, a predetermined pressing force can be applied to the drug unit 10 via the cushion material 15 when the rear door 4 is closed, and the drug unit 10 can be applied. Can be kept in a well-sealed state. Further, since the cushion material 15 is an elastic member, it is possible to suppress an impact when the drug unit 10 and the cushion material 15 come into contact with each other when the rear door 4 is closed.

(3) The drug unit 10 is impregnated with a fragrance and includes a sheet material 11 housed in a case (between the base portion 20 and the cover portion 30) (FIG. 5). As a result, the effect of fragrance can be exerted again by replacing the sheet material 11 when the effect of fragrance is reduced with the passage of time. That is, the effect of fragrance can be maintained with an inexpensive configuration in which the sheet material 11 is simply replaced. Instead of replacing the sheet material 11, the effect of the fragrance can be maintained by additionally impregnating the sheet material 11 with an fragrance agent. Further, since the sheet material 11 has a simple shape, it is easy to handle, and the sheet material 11 can be easily replaced. Further, by using the sheet material 11, the drug unit 10 can be formed thin as a whole, and the drug unit 10 can be easily arranged in the limited gap CL between the rear door 4 and the center pillar 5.

(4) The cover portion 30 has a passage PA that communicates the rear space SP1 of the cover portion 30 in which the drug (fragrance) is stored and the front space SP2 of the cover portion 30 (FIG. 7A). The surface cover 34 of the cover portion 30 is provided so as to be movable in the front-rear direction with respect to the inner cover 31. In the chemical unit 10, when the surface cover 34 is pushed backward by the pressing force from the cushion material 15, the passage PA is blocked, while the pressing force from the cushion material 15 is removed and the surface cover 34 is pressed by the spring 33. It is configured to open the passage PA when pushed forward (FIGS. 7A, 7B). That is, as the surface cover 34 moves in the front-rear direction, the slit holes 318 and 344 of the cover portion 30 are closed or opened, and the passage PA is closed or opened. As a result, the scent component can be maintained in the sheet material 11 for a long period of time, and the effect of the scent can be sustained.

(5) A fragrance is used as the drug inside the drug unit 10. As a result, the occupant feels the scent when getting on and off the vehicle 1, and the comfort of the occupant is improved.

(7) The vehicle 1 according to the present embodiment includes a drug unit 10, a vehicle body frame 2 having an opening of the rear door 4, and a rear door 4 provided on the vehicle body frame 2 so as to open and close the opening. Prepare (Figs. 1 to 3). The rear door 4 has a front end surface 4a as an attached surface to which the drug unit 10 is attached (FIG. 3). By attaching the drug unit 10 to the rear door 4 in this way, the odor can be efficiently diffused on the movement line of the occupant.

This embodiment can be transformed into various forms. Hereinafter, some modification examples will be described. In the above embodiment, the medicine unit 10 is attached to the front end surface 4a of the sliding rear door 4, but it may be attached to another position of the rear door 4 or other than the rear door 4, and the attachment position of the medicine unit 10 is Not limited to those mentioned above. FIG. 10 is a perspective view showing an example in which the drug unit 10 is attached to the front door 3 on the driver's side. In the example of FIG. 10, the drug unit 10 is attached to the upper end surface of the front door 3 in a substantially horizontal posture so that the longitudinal direction of the drug unit 10 is in the front-rear direction. Although not shown, the rear door may be configured as a hinge-type rear door that can rotate around the hinge portion as a fulcrum, and the drug unit 10 may be arranged between the rear end portion of the rear door and the C-pillar. ..

The drug unit 10 may be attached to the vehicle body side (body frame 2 side) instead of the door side. For example, the drug unit 10 may be attached to the rear end surface 5a of the center pillar 5, and the cushion material 15 may be attached to the front end surface 4a of the rear door 4. That is, of the pair of facing surfaces facing each other (front end surface 4a, rear end surface 5a), the first facing surface to which the drug unit 10 is attached and the second facing surface to which the cushion material 15 is attached are doors. It may be either the side or the vehicle body side. If the drug unit 10 is attached to the vehicle body side, the scent can be efficiently diffused to the occupants in the vehicle. On the other hand, if the drug unit is attached to the door side, the scent can be diffused at a place away from the vehicle body.

In the above embodiment, a single chemical unit 10 is attached to the rear door 4 via the rear adhesive surface 212 (attachment surface). That is, although a single drug unit 10 is attached to a single door, a plurality of drug units 10 may be attached to at least one of the door side and the vehicle body side for a single door. FIG. 11 is a perspective view of the vehicle 1 showing an example thereof. In FIG. 11, a plurality of drug units 10 are attached to a back door 6 rotatably provided in the vertical direction with the upper end as a fulcrum. That is, the drug unit 10 is attached to the lower end of the back door 6 and the outside (right side, left side, lower side) of the opening of the vehicle body frame 2 facing the peripheral edge of the back door 6, respectively. This allows the scent to be diffused over a wide area. When some scent components disappear, other scent components can maintain the effect of the scent.

Instead of attaching multiple drug units to a single door, a single drug unit may be attached to multiple doors. FIG. 12 is a front view of a part of the center pillar 5 schematically showing an example thereof, and more specifically, a front view of the vicinity of the central portion in the vertical direction of the center pillar 5. In FIG. 12, the center pillar 5 straddles the axis CL1 in the central portion in the front-rear direction of the center pillar 5, that is, the axis CL1 which is the boundary line between the front door (first door) and the rear door (second door) (not shown). The drug unit 10A is attached to the door. Therefore, the drug unit 10A is configured to be wide, and when the front and rear doors are closed, the front side of the drug unit 10A is pressed by the front door, and the rear side of the drug unit 10A is pressed by the rear door. As a result, the number of drug units 10A can be saved.

In the above embodiment, the drug unit 10 is pressed via the cushion material 15 when the door is closed, but the configuration of the pressing member is not limited to that described above.
