DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arrangement structure of a canister mounted on an automobile.

[0002]

2. Description of the Related Art When a fuel supply port is opened at the time of refueling in a state where fuel vapor generated in a fuel tank mounted on an automobile is filled in an upper space of the fuel tank, the fuel vapor in the fuel tank is reduced. It will flow out and pollute the atmosphere. As a countermeasure, an evaporative fuel control device for collecting and processing the evaporative fuel generated in the fuel tank is provided.

[0003] This evaporative fuel control apparatus has a valve 10 above a fuel tank 101 as schematically shown in FIG.
The evaporative line 103 communicating with the canister 104 is connected to the canister 104 and the engine 105 via the engine 105.
And a purge line 106 interposed with a check valve 107.

[0004] With this configuration, when the fuel vapor generated in the fuel tank 101 reaches a set value, the valve 102 is pushed open, and the fuel vapor in the fuel tank 101 is led out to the canister 104 via the evaporation line 103, and The fuel vapor introduced into the canister 104 is once absorbed and stored in an adsorbent in the canister 104. The check valve 107 is opened by the negative pressure of the intake system due to the operation of the engine 105, and the evaporated fuel stored in the canister 104 is supplied to the intake system of the engine 105 together with the purge air to be processed by the combustion in the engine 105. You.

The canister is usually arranged in the engine room. However, various parts such as engine auxiliary parts and electric parts are mounted in the engine room, so that the space for disposing the canister is limited, and the requirement of the canister is reduced. Since the size of the canister is increased with an increase in the capacity, the canister is sometimes mounted on the rear portion of the vehicle body where it is relatively easy to secure the arrangement space.

A structure in which the canister is mounted on the rear part of the vehicle body is disclosed in, for example, Japanese Patent No. 2545376, and as shown in FIG. 11, the rear wheel house inner 112 near the axle center line of the rear wheel 111.
A recess 113 is formed on the side surface of the bracket 11 toward the passenger compartment, and a canister 115 is accommodated in the recess 113 so that the bracket 11
There is a mounting structure of a canister that is fixed through the 6.

Further, as disclosed in Japanese Patent No. 2910607 and as disclosed in FIG. 12, right and left rear side frames 121 and left and right rear side frames 1 are provided.
The canister 125 is disposed in a space surrounded by a cross member 122 erected between the first and second members 21 and an exhaust pipe 123 disposed near the rear side frame 121 and the cross member 122 and passing exhaust gas from the engine.

However, since the canister 115 is disposed near the side of the vehicle body, there is a concern that the canister 115 may be damaged when a predetermined or more impact load is applied to the vehicle body from the side due to a side collision or the like. .

According to Japanese Patent No. 2910607, the canister 125 is arranged in a space surrounded by the rear side frame 121, the cross member 122, and the exhaust pipe 123. The heat of the gas is applied to the rear side frame 121, the cross member 122 and the exhaust pipe 12.
The gas accumulates in the space surrounded by 3 and the ambient temperature in the space rises to heat the adsorbent in the canister 125, thereby promoting the desorption of fuel from the adsorbent.

However, since the canister 125 is attached to the floor panel 124 by a bracket or the like in the vicinity of the rear side frame 121 and the cross member 122, the deformed rear side frame is subjected to an impact load exceeding a predetermined amount due to a collision or the like. 121, the exhaust pipe 123, the cross member 122, etc.
There is a concern that the canister 125 may be damaged by contact with the canister 125.

Further, since the exhaust pipe 123 disposed close to the canister 125 has a relatively high temperature, the case of the canister 125 needs to be formed of a heat-resistant material, which limits the degree of freedom in design. In addition, there is a concern that manufacturing costs may increase.

Accordingly, a first object of the present invention, which has been made in view of the above points, is to provide a canister arrangement structure for an automobile which can protect the canister from an impact load due to a collision or the like.
