Generally, vehicles with HST have a pedal on the right side of the vehicle body when HST operation is performed using a foot pedal, but in some cases, such as agricultural tractors, the brake pedals are double-brake in order to act on the left and right brakes independently. It has been difficult to provide enough space on the steps for people to rest their feet on the steps or in small vehicles. Therefore, when getting on or off the vehicle, there is a risk that the vehicle may start moving unexpectedly due to the rider getting his or her shoes caught on the pedal. In addition, when performing HST operation using a foot pedal and a manual lever, there is no place to rest your right foot when using a manual lever, so you may have to keep your foot on the pedal at all times or put your foot under the brake pedal. I feel tired because I have to
This resulted in drawbacks such as not being able to step on the brake immediately. On the other hand, there are pedals that have smaller HST pedals, and pedals that have separate treads at the front and rear by removing the middle part of the pedal, but the former have the disadvantage of being extremely difficult to operate and prone to erroneous operation. Moreover, the latter had the disadvantage that it was necessary to take the trouble to step on the foot when switching from forward to reverse, resulting in poor operating efficiency.

Therefore, in the present invention, the HST operating pedal is configured to be long in the front-rear direction, and is arranged with an upward slope in the front, and the operating pedal is arranged parallel to the inside of the brake pedal, and the front part of the operating pedal and the brake pedal are connected to each other. The center portions are arranged approximately in the same direction in the front and back direction, and the outer side of the operating pedal is cut diagonally so that it becomes narrower at the rear, so that the foot can be placed on the outer side of the operating pedal and behind the brake pedal. It is an object of the present invention to provide an operating pedal for a vehicle equipped with a hydraulic transmission device, which secures a space for carrying the vehicle and eliminates the above-mentioned drawbacks.

Since the present embodiment has the above-described configuration, when the tractor 1 is operated on the foot pedal 13 by driving on the road or performing work such as a front loader, when the foot is placed on the pedal 13, the safety pedal 21 is moved to the arch of the foot. The pedal 13 can be rotated by contacting the pedal 13 to release the lock. And pedal 1
When you step on the front part of 3, link mechanism 17 and HST
The HST operation arm 20 is rotated via the link 19, the HST 9 is shifted forward at a speed corresponding to the amount of rotation of the pedal 13, and the tractor 1 is moved forward at a predetermined speed. Also, if you step on the rear part of the pedal 13,
Similarly, the HST 9 is shifted in the reverse direction to move the tractor 1 backward at a predetermined speed. At this time, since the pedal 13 has an upward slope in the front, it is easy to operate, and by moving your right foot in parallel and slightly laterally, you can press the left and right brake pedals 23a and 23b to brake quickly and accurately. can be operated. Further, when traveling at a constant speed during plowing, mowing, rotary tilling, etc., the manual lever 15 is used to operate the vehicle. At this time, take your foot off the foot pedal 13 and use the safety pedal 21 to
The driver can lock the vehicle in the neutral position, place his right foot on the space A above the step 11a, and continue driving in a comfortable position. Further, when operating the brakes or the differential lock, the left and right brake pedals 23a, 23b or the differential lock pedal 26 can be pressed quickly and accurately by slightly moving the right foot in the front and rear directions. Note that the clutch pedal 27 is installed on the left step 11b, but as mentioned above,
Since the HST operating pedal 13 can be used for all forward, reverse, gear shifting, and stopping operations, there is no need to operate the clutch pedal 27 during normal driving. However, the clutch pedal 27 can be effectively used as a live PTO clutch when attaching an attachment to a work machine.

As explained above, according to the present invention, the HST operation pedal 13, which is long in the front and rear direction, is provided with an upward slope in the front, and the pedal is connected to the brake pedal 23.
a and 23b, and the front part of the HST operating pedal and the center part of the brake pedal are arranged approximately in line with each other in the front-rear direction, so the HST operating pedal and the brake pedal can be operated with the same foot in the front-rear position. This combined with the fact that the driver can quickly and accurately reposition his or her foot and apply the brakes quickly even in sudden situations, and that the driver can place his or her foot on the HST operating pedal in a natural position. Operability can be greatly improved. In addition, since the outside of the HST operating pedal 13 is cut diagonally so that it is narrower at the rear, a space A can be secured to place the foot on the step 11a of the HST operating pedal behind the brake pedal, and the space A can be secured for operation. The foot can be rested when the pedals are not operated, and the foot can be quickly and accurately moved to each pedal in an instant to react quickly.
