[0017]
As shown in FIG. 3, the engine 3 is mounted on a front frame (an example of an engine mounting frame) 12 connected to the mission case 4 via four rubber bushes 13. The front frame 12 is configured in a frame shape including a pair of left and right vertical frames 14 and 15 and front and rear horizontal frames 17 and 18 that connect and integrate them. A muffler 19 is provided on the left outer side of the left vertical frame 14. Is arranged, and the battery 20 is arranged on the right outer side of the right vertical frame 15.
[0018]
As shown in FIG. 2, on the upper side of the front frame 12, left and right front steps 21 and 22, a front cover 24 having a front mask portion 23 and the like, a bonnet 25 that rises from the front cover 24, and a steering wheel A control tower 27 for supporting the handle 26 is provided. The bonnet 25 having a shape lacking a rear surface and a bottom surface is swingably supported so as to be openable and closable around a left and right fulcrum P provided at the upper portion of the rear portion. Next, a support structure for the battery 20 will be described.
[0019]
As shown in FIGS. 2 to 6, the battery 20 is mounted in the left-right direction at a position below the right front step 22 using the battery mounting device A. That is, a bracket tower 28 made of a bent plate is fixedly erected on the outer surface of the right vertical frame 15, and the battery seat 29 is cantilevered and supported on the bracket tower 28 so as to protrude to the left lateral side. At the same time, the mounting device A is configured by providing an attaching / detaching mechanism a that can be moved laterally or downward from the right vertical frame 15 to detach the battery seat 29.
[0020]
The battery seat 29 is formed of a plate material in which tongue pieces 29b, 29c, 29d, and 29e for positioning the front, rear, left, and right side surfaces of the battery 20 are bent on the bottom surface 29a on which the battery 20 is placed, Is mounted on the pedestal portion 28a of the bracket tower 28, and the outer end thereof is fixed to the front frame 12 by being supported on the upper portion of the bracket tower 28 via a pair of front and rear bar rods 30 and 30.
[0021]
The tension bar bolt 30 has its crank portion 30a inserted through a hole 31 formed in the upper part of the front and rear side portions of the bracket tower 28, and a tip screw portion 30b between the right side surface 29e and the bottom surface 29a. The installation is provided by hanging the nut 33 through the notch 32 to be formed. An upper tongue piece 28 </ b> C is formed at the upper end of the bracket tower 28 so as to face the upper surface of the battery 20 and restrict its upward movement.
[0022]
With the above configuration, the battery 20 is equipped by tightening and fixing the two tension bar bolts 30 and 30 with the inner end of the battery seat 29 placed on the pedestal portion 28a. That is, the battery seat 29 on which the battery 20 is placed is cantilevered so as to protrude laterally from the front frame 12, and the battery seat 29 is moved laterally or downward from the front frame 12. An attachment / detachment mechanism a that can be freely detached is provided.
[0023]
The attachment / detachment mechanism a is composed of the tension bar bolt 30 and its nut 33. Therefore, as the attachment / detachment operation of the battery 20, if the two nuts 33 are removed, the battery seat 29 becomes free. If it moves rightward in the left-right direction of the airframe to eliminate interference with the pedestal portion 28a, then if it moves laterally diagonally downward, as shown in FIG. 2, the battery 20 is taken out from below the right front step 22 be able to. When installing, the reverse procedure is sufficient.
[0024]
As shown in FIGS. 2 and 5, the battery 20 is oriented so that the anode terminal 34 is inside the fuselage and the cathode terminal 35 is outside the fuselage, and the anode terminal 34 is below the bonnet 25 in plan view. In addition, the cathode terminal 35 is positioned below the right front step 22, respectively. And in the open attitude of the bonnet 25, it sets to the state which the anode terminal 34 faces the bonnet opening part in planar view.
[0025]
In addition, since the ground wire 36 for conducting the cathode terminal 35 and the vehicle body is provided, the vehicle body connection portion 36a at the tip of the ground wire cannot be brought into contact with the anode terminal 34 when the ground wire 36 is disconnected from the vehicle body. Insulating means b is provided. That is, the vehicle body side connection portion 36 a of the ground wire 36 is bolted to the upper surface of the right vertical frame 15 and the intermediate portion of the ground wire 36 is locked to the rear side surface 29 c of the battery seat 29 using the clamp 37. .
[0026]
That is, even if the vehicle body side connection portion 36a is removed from the upper surface of the right vertical frame 15, the clamp 37 restricts the tip end portion of the ground wire 36 so that it can move freely. Does not physically reach the anode terminal 35. In this case, the insulating means b is constituted by the clamp 37.
[0027]
[Another embodiment]
As shown in FIG. 7, the battery 20 may be a mounting device A that is arranged in the front-rear direction so that the anode terminal 34 is behind and the cathode terminal 35 is front. Even in this case, the anode terminal 34 is clearly arranged to face the bonnet opening, and basically follows the same structure as that of the present embodiment.
[0028]
The lead wire 36 of the cathode terminal 35 is bolted to the front side surface of the bracket tower 28. In this case, the length of the ground wire 36 is very short. It does not reach the anode terminal 34 physically. Therefore, in this structure, the short ground wire 36 by the battery front-back arrangement also serves as the insulating means b, and the clamp 37 is not necessary.
[0029]
In the present embodiment shown in FIG. 4, the vehicle body side connection portion 36 a of the ground wire 36 may be bolted to the front side surface portion of the bracket tower 28. Although not shown, when the tip end portion of the ground wire 36 is pulled and urged toward the cathode terminal 35 by an elastic mechanism such as a spring or rubber strap, the bolt is loosened and the vehicle body side connection portion 36a is removed from the vehicle body. When configured so that the vehicle body part is not automatically touched (non-grounded state), it is ensured that when a lead wire is removed from the anode terminal 34, a tool such as a spanner does not short-circuit even if it touches the vehicle body part. Can appear.
