【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show a vehicle auxiliary equipment arrangement structure according to an embodiment of the present invention, 1 is a front fender which constitutes an outer surface of a front portion of a vehicle, and 2 is an inside of the front fender 1. Is a wheel apron that is located at the side and forms the side wall of the engine room 3, and the wheel apron 2 is formed with a wheel housing portion 2a. Further, the wheel apron 2 includes a first vertical portion 2b joined to a frame 4 extending in the vehicle front-rear direction on the front side of the wheel housing portion 2a and a vehicle outer side (that is, a front side) from an upper end of the vertical portion 2b. It has a horizontal portion 2c that extends substantially horizontally on the fender 1 side) and a second vertical portion 2d that extends substantially vertically upward from the vehicle outer side end portion of the horizontal portion 2c. The frame 4 is joined to the side surface of the first vertical portion 2b on the engine room side, and forms a closed cross section extending in the vehicle front-rear direction together with the vertical portion 2b.

A secondary air pump 6 as a vibration generating component is arranged below the horizontal portion 2c, and an air amount adjusting device 7 is arranged in front of the secondary air pump 6. The suction port of the secondary air pump 6 is connected to the other end of the first air supply pipe 8 whose one end is connected to an air cleaner (not shown) arranged in the engine room 3 One end of the second air supply pipe 9 is connected to the discharge port of the air pump 6, and the other end of the second air supply pipe 9 is connected to the inlet of the air amount adjusting device 7. One end of a third air feed pipe 10 is connected to the outlet of the air volume adjusting device 7, and the other end of the air feed pipe 10 penetrates the wheel apron 2 (first vertical portion 2b). Is installed in the engine room 3 and is connected to the exhaust system of the engine. Then, by operating the secondary air pump 6, air is supplied from the air cleaner to the air amount adjusting device 7 through the first and second air supply pipes 8 and 9, and the air amount adjusting device 7 adjusts the supply amount. After that, it is introduced as secondary air into the exhaust system of the engine through the third air supply pipe 10 and is used for oxidizing HC and CO in the exhaust gas.

Further, below the horizontal portion 2c, a radiator sub-tank 11 as a resin component is provided between the air pump 6 and the wheel housing portion 2a of the wheel apron 2 in the vicinity of the secondary air pump 6. It is arranged. The water inlet / outlet portion 11a of the sub tongue 11 extends through the horizontal portion 2c into the engine room 3, and is connected to a radiator via a pipe (not shown). Two upper and lower mounting portions 11b and 11c are integrally formed on the side surface of the sub tank 11 facing the wheel apron 2 (first vertical portion 2b), and the upper mounting portion 11b is mounted on the side surface of the wheel apron 2. It is bolted to a portion that forms a closed cross section with the frame 4, and the lower mounting portion 11c is bolted to a portion that is lower than the joint portion of the wheel apron 2 with the frame 4.

On the other hand, a mounting bracket 13 is attached to the secondary air pump 6, and the mounting bracket 13 has a first mounting portion 13 a extending above the air pump 6 and a mounting bracket 13 below the air pump 6. It has the extending 2nd attachment part 13b. The first mounting portion 13a is bolted to the plate 14 fixed to the second vertical surface 2d of the wheel apron 2, and the second mounting portion 13b is formed on the sub tank 11. It is bolted to the attached seat portion 11d. The air amount adjusting device 7 is attached to a portion of the wheel apron 2 that forms a closed cross section with the frame 4 via a mounting bracket 15. In FIG. 2, 21 is a bonnet.

Next, to explain the operation and effect of the above-mentioned embodiment, the vibration generated in the secondary air pump 6 during the operation of the secondary air pump 6 is transmitted from the first mounting portion 13 a of the mounting bracket 13 to the first mounting portion 13 a of the wheel apron 2. It is transmitted to the vertical portion 2 d of the second mounting portion 13 and is transmitted to the sub tank 11 from the second mounting portion 13 b of the mounting bracket 13. At this time, since the wheel apron 2 is made of a thin plate material, the wheel apron 2 itself deforms and radiates vibration energy against the vibration. Further, since the sub-tank 11 is made of a resin which is easily deformed, it is deformed in the same manner as the wheel apron 2 with respect to vibration and radiates vibration energy. From this fact, the vibration of the air pump 6 is hardly transmitted to the frame 4 and further to the vehicle compartment side through the wheel apron 2 or the sub tank 11, and it is possible to reduce the indoor noise.

Further, since the so-called dead space outside the engine room 3 is located below the horizontal portion 2c of the wheel apron 2, the secondary air pump 6, the air amount adjusting device 7, and the radiator sub-tank 11 are arranged at this location. By doing so, the parts can be easily and appropriately arranged in the engine room 3.

Furthermore, since the secondary air pump 6 is not directly connected to the frame 4 or the portion of the wheel apron 2 to which the frame 4 is joined, the deformation of the frame 4 during a frontal collision may cause the secondary air pump 6 to deform. The desired shock absorbing effect can be exerted without being restricted by. Since the air amount adjusting device 7 is a small component and is attached only at one place where the wheel apron 2 is joined to the frame 4, the deformation of the frame 4 at the time of a frontal collision is prevented by the air amount adjusting device 7. It is not regulated. The mounting portion 11b of the sub-tank 11 is mounted on a portion of the wheel apron 2 that is joined to the frame 4, but the sub-tank 11 is made of resin, and when the frame 4 is deformed during a frontal collision, the sub-tank is mounted. Since the mounting portion 11b of 11 is broken, the deformation of the frame 4 is not restricted by the sub tank 11.
