  Thus, when the bracket is fastened to the engine side via the second boss part and attached, and the accessory equipment is bolted and held on the first boss part of the bracket, the accessory equipment is attached to the engine side. On the other hand, if the cooling water pipe is connected to the inlet side and the outlet side of the cooling water channel drilled in the bracket, the cooling water pipe is also supported by the pipe at the same time.

  Here, the positional relationship between the accessory equipment and the cooling water pipe is always unchanged because it is held by the same bracket, and sufficient consideration is given to variations in assembly accuracy and component precision between these accessory equipment and the cooling water pipe. Since it is not necessary to take a clearance, the arrangement of the two as close as possible is realized, and the arrangement space can be greatly reduced in size.

  Further, in the present invention, it is preferable that the first boss portion for holding the accessory equipment by bolt fastening is provided at a plurality of locations corresponding to different accessory equipment. A plurality of brackets that have been divided for each accessory in the prior art are made into one unit as a component, and the number of parts is reduced as compared with the conventional case.

  Furthermore, when carrying out the present invention more specifically, it is preferable that the inlet pipe is fitted and fixed to the inlet side of the cooling water channel, and the outlet pipe is fitted and fixed to the outlet side of the cooling water channel, In this way, it is possible to easily connect the cooling water pipe to the cooling water passage of the bracket via the inlet pipe and the outlet pipe.

  According to the bracket of the present invention described above, various excellent effects as described below can be obtained.

  (I) According to the invention described in claim 1 of the present invention, it is possible to realize the closest arrangement of the accessory equipment and the cooling water pipe as much as possible, thereby greatly reducing the arrangement space. Therefore, the mountability of the engine on the vehicle can be improved as compared with the conventional case.

  (II) According to the invention described in claim 2 of the present invention, a plurality of brackets conventionally divided for each accessory can be sub-united as one component, thereby reducing the number of components. Since it can be reduced as compared with the prior art, it is possible to simplify the work of assembling the accessory equipment on the engine side, reduce the work load, and significantly reduce the cost.

  (III) According to the invention described in claim 3 of the present invention, the cooling water pipe can be easily connected to the cooling water channel of the bracket via the inlet pipe and the outlet pipe.

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

  1 to 4 show an example of an embodiment for carrying out the present invention, and an example of a bracket 4 for attaching an engine hanger 1 and an intake pipe 2 to an engine 3 as accessory equipment is shown. A boss portion 5 (first boss portion: see FIGS. 2 to 4) for holding the base end portion 1a bent in an L shape of the engine hanger 1 by bolt fastening, and a longitudinal direction of the intake pipe 2 as appropriate. A boss part 6 (first boss part) for holding the flange part 2a formed to project at a position by bolt fastening, and a boss part 7 (second boss part) for fastening its own bolt to the engine 3 side ) And a cooling water channel 8 (see FIG. 2) drilled so as to penetrate in the vertical direction.

  More specifically, in the case of the bracket 4 shown here, a boss portion 7 for bolting itself to the engine 3 side is formed at the right end portion in FIG. A bolt 9 (see FIG. 1) is tightened into a bolt hole 7 a that is opened in two upper and lower stages 7 and is attached to the engine 3.

  A boss portion 5 for the engine hanger 1 is formed at the left side position in FIG. 1 close to the boss portion 7 so as to protrude from the boss portion 7 to the anti-engine 4 side. At the left side position (left side in FIG. 1), a boss portion 6 for the intake pipe 2 extending in a curve is formed so as to move away from the engine 3 toward the tip side. Bolt holes (not shown) opened in the base end portion 1a of the engine hanger 1 and the flange portion 2a of the intake pipe 2 are aligned with the upper and lower two-stage bolt holes 5a and 6a opened in the end face on the side. 10 and 11 (see FIG. 1).

  On the other hand, a cooling water passage 8 penetrating in the vertical direction is formed in the central portion of the bracket 4 in the width direction (left-right direction in FIG. 1) by processing after casting, and below the cooling water passage 8. The inlet pipe 12 is fitted and fixed by press-fitting into the inlet portion opened downward, and the outlet pipe 13 is fitted and fitted into the outlet portion bent and opened to the right in FIG. It is fixed. In FIG. 1, reference numeral 14 denotes a cooling water pipe connected to the inlet pipe 12 and the outlet pipe 13 by fitting the end portions thereof.

  Thus, when the bracket 4 is bolted and attached to the engine 3 side via the boss portion 7, the engine hanger 1 and the intake pipe 2 are respectively bolted and held on the boss portions 5 and 6 of the bracket 4, The engine hanger 1 and the intake pipe 2 are attached to the engine 3 side. On the other hand, an inlet pipe 12 and an outlet pipe 13 are provided on the inlet side and the outlet side of the cooling water channel 8 drilled in the bracket 4. If the cooling water pipe 14 is connected, the cooling water pipe 14 is also supported by the pipe.

  Here, the arrangement relationship between the engine hanger 1 and the intake pipe 2 and the cooling water pipe 14 is always unchanged because it is held by the same bracket 4, and the assembly of the engine hanger 1 and the intake pipe 2 and the cooling water pipe 14 is constant. Since it is not necessary to provide a sufficient clearance in consideration of variations in accuracy and component accuracy, the arrangement of the two as close as possible is realized, and the arrangement space can be greatly reduced in size.

  In particular, in the present embodiment, since the boss portions 5 and 6 are provided at a plurality of locations corresponding to the two accessory equipments of the engine hanger 1 and the intake pipe 2, the engine hanger 1 and the intake pipe 2 are conventionally provided. A plurality of brackets that are used individually corresponding to each other are sub-united as one part, and the number of parts is reduced as compared with the conventional art.

  Therefore, according to the above embodiment, the engine hanger 1 and the intake pipe 2 and the cooling water pipe 14 can be arranged as close as possible, and thus the arrangement space can be greatly reduced in size. Since the mountability of the engine 3 to the vehicle can be improved as compared with the conventional one and the number of parts can be reduced as compared with the conventional one, the assembly work of the engine hanger 1 and the intake pipe 2 to the engine 3 side can be performed. Simplification can reduce the work burden and drastically reduce the cost.

  Further, the inlet pipe 12 is fitted and fixed to the inlet side of the cooling water channel 8, and the outlet pipe 13 is fitted and fixed to the outlet side of the cooling water channel 8, so that the inlet pipe 12 and the outlet pipe 13 are interposed. Thus, it is possible to easily connect the cooling water pipe 14 to the cooling water channel 8 of the bracket 4.
