Based on the above, the invention according to claim 3 connects the transmission case 11 to a high position separated in the front-rear direction of the main transmission case 10 and maintains the oil level of the transmission case 11 at this connection portion. The configuration of the riding management work vehicle is characterized in that the oil level weir 12 is formed. With this configuration, the configuration of the main transmission case 10 and the transmission case 11 that are spaced apart from each other in the front-rear direction can reduce the size of the transmission case as a whole. The outflow of the lubricating oil in the transmission case 11 to the main transmission case 10 is restricted by the oil level weir 12, so that the lubrication can be stably maintained.

Here, the transmission case 11 and the main transmission case 10 are connected to a pipe-shaped connecting case 56.
Are linked by The transmission case 11 is provided with a gear 33, and a gear shaft 57 disposed below the connection case 56 is interlocked with the transmission shaft 31 on the engine 2 side. The rear power take-out shaft 34 is connected to a gear shaft 58 disposed above the connection case 56. The main clutch case 32 disposed between the front and rear transmission cases 10 and 11 has a main clutch 59.
Is provided so that rotation transmission between the rear end of the gear shaft 57 and the front end of the input shaft 60 on the main transmission case 10 side can be turned on and off.

The oil level weir 12 is formed at the junction of the transmission case 11 with the connection case 56 and projects into the connection case 56 at a predetermined height to partition the front and rear. The oil level weir 12 may be formed integrally with the submission case 11 or the connection case 56, or may be mounted with an independent partition plate or the like between the cases 11 and 56. Above the oil level weir 12, a communication port 61 through which the lubricating oil between the upper surface of the inner periphery of the connection case 56 can move back and forth is opened. The normal oil level is set at both communication cases 10,
11 is supplied with lubricating oil.

The formation of the oil level weir 12 keeps the lubricating oil in the transmission case 11 high even when the vehicle body 1 is greatly inclined back and forth,
Can be maintained, and the bottom of the connection case 56 can be formed as low as possible, so that the amount of oil contained can be increased.

Further, such an oil level weir 12 is provided between the front and rear intermediate portions of the connecting case 56 and the main transmission case 1 at the rear end.
It can also be formed at the connection with 0. Next, based mainly on FIGS. 1 to 3 and FIGS. 11 to 14, the invention described in claim 4 is based on one side located on the left and right sides of the vehicle body 1 between the front wheel 13 and the rear wheel 14. , A fuel tank 16 is arranged below the side floor 15L, and a battery 17 is arranged below the side floor 15R on the other side. Thus, the heavy fuel tank 16 and the battery 17 are separately disposed below the side floors 15L and 15R on both left and right sides of the vehicle body 1, so that the high floor form of the vehicle body 1 is maintained and the left and right sides are maintained. Weight balance can be maintained. In addition, it facilitates refueling of the fuel tank 16 and inspection of the battery 17.

According to a fifth aspect of the present invention, the battery case 18 for fitting and supporting the battery 17 is provided rotatably so as to be inclined laterally outward with respect to the support bracket 19 on the vehicle body 1 side. It is characterized by the following. As a result, the battery case 18 supporting the battery 17 can be tilted and rotated to the outside of the side floor 15R.
7 is easy to put in and out, and the upper side floor 15R
Can be narrowed, and a high floor form can be maintained.

When the fuel tank 16 is located below the left side floor 15L, the battery 17 is placed below the right side floor 15R. Each of the fuel tank 16 and the battery 17 is mounted on the floor frame 2.
4 but the upper surface should be as
It is configured so as to be close to the lower surfaces of the L and 15R to form a raised floor. Reference numeral 62 denotes a boarding / alighting step attached to the outside of the floor frame 24.

In the form of maintaining a large capacity, the capacity of the fuel tank 16 can be increased by using a wide side floor 15L by limiting the depth and increasing the front, rear, left, and right dimensions. In addition, since the battery 17 is tilted toward the outside of the side floor 15R by rotating the bottom of the battery case 18 around the support pin 63 on the back side and the bottom portion to the back side, this battery 17 can be easily taken in and out of the battery case 18. A pair of front and rear support brackets 19 are mounted under the floor frame 24, and a box-shaped battery case 18 having an open upper and lower side is rotatable by fitting a support pin 63 on an upper rear side into a support hole 66 of the support bracket 19. Hanged on.

The battery case 18 has a restriction pin 6
4 protrudes forward and backward, and is fitted and guided in an arc-shaped long hole 65 formed in the support bracket 19, thereby regulating the tilt rotation area of the battery case 18. This support pin 63
A set bolt 70 is provided in front of the support bracket 19.
Through the holes 71 of the battery case 18 and the bolt holes 72 of the battery case 18, it is possible to maintain the taking posture of the battery 17. By inserting and removing the set bolt 70, the battery case 18 can be turned around the support pin 63.

Reference numeral 67 denotes a fastening rod for preventing the battery 17 from floating with respect to the battery case 18, reference numeral 68 denotes a holding angle, and reference numeral 69 denotes a fastening nut. The attachment and detachment of the battery 17 from the battery case 18 can be performed by operating the nut 69 to loosen the holding angle 68.
