Has been.

  One end of an electrical wiring 35 is connected to each relay 33, and the electrical wiring 35 extends downward and rearward from each relay 33 and is bundled together by a binding fixture 36. In this state, each electric wiring 35 is drawn out to the engine room 18 side through a wiring hole 37 penetrating the partition wall 4a. Since the bundling fixture 36 is fixed on the right side wall 4c by the bolt 38, the electric wiring 35 from each relay 33 is prevented from being loosened at the intermediate position and kept in a state of being separated from the bottom wall 4e. .

  One end of each electrical wiring 40 is connected to the left and right headlights 25 described above, and each electrical wiring 40 extends rearward. The left electrical wiring 40 extends from the headlight 25 to the rear partition 4a, extends rightward from the bottom wall 4e while maintaining a predetermined height, and is fixed on the partition 4a by a pair of fixing brackets 41.

The left electrical wiring 40 extends forward on the right side of the partition wall 4 a, then turns back and merges with the electrical wiring 40 from the right headlight 25, and is bound and fixed together with the electrical wiring 35 from the relay 33. They are bundled by a metal fitting 36 and pulled out to the engine room 18 side.

  Brackets 42 are erected at the rear positions of the left and right headlights 25 on the bottom wall 4e, and an intermediate portion of the electric wiring 40 from the headlight 25 is fixed to the upper part of the brackets 42. As a result, the electric wiring 40 is prevented from slackening at the intermediate portion, and is kept away from the bottom wall 4e.

  Also, as shown in FIG. 5, an electrical wiring 44 provided with a connector 44a at one end is fixed to the fixing bracket 41 on the partition wall 4a together with the electrical wiring 40 from the left headlight 25. 44 is also drawn out to the engine room 18 side along with other electric wires 35 and 40. Although not shown, the connector 44a is connected to an air flow sensor and a clogging sensor provided in the air cleaner 32 described above.

  As described above, the electric wires 35, 40, 44 from the auxiliary machines such as the headlight 25, the air cleaner 32, and the sensor of the relay 33 are drawn into the engine room 18 in a bundled state, as shown in FIG. The right side wall 4c is fixed to the right side wall 4c by a fixing metal fitting 45 while being extended obliquely upward rearward.

The devices to which the auxiliary machines 25, 32, 33 are connected via the electrical wirings 35, 40, 44 are installed in various parts of the vehicle body. For example, meters and switches to which the relay 33 and the headlight 25 are connected. (Equipment) is provided on the operation console 11, and an ECU 46 (equipment) to which the sensor of the air cleaner 32 is connected is arranged in a tool box under the driver's seat 12.
Therefore, each electrical wiring 35, 40, 44 is appropriately branched at an appropriate position near the counterpart device on the right side wall 4c, and is extended and connected to the device. For example, the electric wiring 44 from the sensor of the air cleaner 32 is branched at the upper end of the right side wall 4c in FIG. 4, and the connector at the tip of the electric wiring 44 is connected to the ECU 46 in the tool box.

  As is clear from the above description, the electrical wiring 35 from each relay 33 is separated from the bottom wall 4e while being prevented from slacking at the middle position by the binding fixture 36, and the electrical wiring from the left and right headlights 25. 40 is prevented from slackening at the intermediate position by the bracket 42, and the electric wiring 40 on the left side thereof is fixed to a predetermined height on the partition wall 4a by a pair of fixing brackets 41, and the electric wiring 44 from the sensor of the air cleaner 32 is also provided. It is fixed to a predetermined height on the partition wall 4a by a pair of fixing brackets 41. As a result, in the auxiliary machine chamber 21, all the electrical wirings 35, 40, 44 are fixed in a state of being separated from the bottom wall 4e.

  During the compacting operation by the Macadam roller 1, mud and the like adhering to the outer peripheral surfaces of the left and right front rolling wheels 2 are scraped off by the scraper 20, so that dust around the auxiliary machine chamber 21 adjacent to it And dust are scattered. Further, when the engine room 18 is maintained, the auxiliary machine cover 22 of the auxiliary machine room 21 is used as a scaffold for the worker, so that mud or the like adhering to the shoe sole of the worker remains on the auxiliary machine cover 22. .

As a result, dust or sand enters the auxiliary machine chamber 21 and gradually accumulates on the bottom wall 4e. In this embodiment, all the electrical wirings 35, 40, and 44 in the auxiliary machine chamber 21 are connected to the bottom wall. Since they are separated from the top of 4e, dust and dust are only deposited below the electric wirings 35, 40, and 44, and the electric wirings 35, 40, and 44 are not buried in the dust and sand.
Therefore, troubles such as short-circuiting of the electrical wirings 35, 40, 44 and corrosion of the terminals can be prevented in advance. Moreover, although it is necessary to regularly clean the dust and sand deposited on the bottom wall 4e, the cleaning work can be easily performed without being obstructed by the electric wirings 35, 40, and 44.

  Further, as is apparent from FIG. 5, the electrical wiring 40 from the left and right headlights 25 is longitudinally cut in the auxiliary machine chamber 21 in the front-rear direction, and therefore has a bottom wall as compared with the other electrical wirings 35 and 44. Although the distance which requires erection (separate from the bottom wall 4e) on 4e is long, since the intermediate location is being fixed to the bracket 42, the contact with the bottom wall 4e by slack can be prevented reliably. Moreover, the present invention can be implemented with a simple configuration in which the bracket 42 is erected on the bottom wall 4e.

By the way, it is desirable that contact with the bottom wall 4e of the auxiliary machine room 21 is avoided as much as possible not only for the electrical wirings 35, 40, and 44 but also for auxiliary machines installed in the auxiliary machine room 21. Another example that considers is described below.
FIG. 6 is a perspective view corresponding to FIG. 3 showing another example of the front vehicle body 4, and FIG. 7 is a cross-sectional view corresponding to FIG.

  In this example, the left and right headlights 25 installed on the bottom wall 4e are transferred to the auxiliary machine cover 22 in the above embodiment. That is, the left and right headlights 25 are attached to the auxiliary machine cover 22 so as to be able to irradiate forward when it is closed. The electric wiring 51 from each headlight 25 is appropriately fixed to the inner surface of the auxiliary machine cover 22 by a fixing bracket 52 while extending to the hinge 23 side, and is bundled together with the other electric wirings 35 and 44 to the binding fixing bracket 36. And pulled out to the engine room 18 side.

In this alternative example, the battery 26 is moved from the auxiliary machine room 21 to another place (for example, the engine room 18), but the battery 26 is installed in the auxiliary machine room 21 as in the above embodiment. You may make it do.
According to another example configured in this manner, since the headlight 25 is not installed on the bottom wall 4e, it is possible to prevent the headlight 25 from being buried in dust or sand, to prevent troubles thereof, and to prevent the bottom wall 4e. It is possible to more easily carry out the cleaning work of dust and sand accumulated on the surface.

This is the end of the description of the embodiment, but the aspect of the present invention is not limited to this embodiment. For example, in the above-described embodiment, the sensors of the relay 33, the headlight 25, and the air cleaner 32 are installed in the auxiliary machine chamber 21 as auxiliary machines, but the auxiliary machines are not limited to this and can be arbitrarily changed. For example, a solenoid valve for controlling the HST or the ECU 46 may be installed in the auxiliary machine chamber 21 as an auxiliary machine.
In the above-described embodiment, the auxiliary machine cover 22 of the auxiliary machine room 21 is opened and closed with the upper end hinge 23 as the center. However, the present invention is not limited to this, and for example, the auxiliary machine with the hinge 23 provided at the lower end as the center. The cover 22 may be opened and closed, or the auxiliary machine cover 22 may be removable from the auxiliary machine room 21.
