  The accelerator operating device 20, the clutch operating device 30, and the change operating device 40 have a structure (see FIGS. 4 and 5) that is installed near each operation object (accelerator 101R, clutch not shown, change pedal 104). ing.

As shown in FIG. 1, the cover includes a torso 51, a thigh 52, a shin 53, an arm 54, and the like. As described above, the step goes to step 103 (the tip of the shin 53). It is attached and fixed by the operation of placing the tank, the operation of sandwiching the tank between the knees (the thigh 52, the connecting part 52a of the shin 53), the operation of grasping the handle with the hand (tip of the arm 54), etc. The auxiliary frame 55 is also fixed.
Further, the torso 51 can be tilted with respect to the thigh 52, and the posture of the driver can be varied (torso 51A).

Next, with reference to FIG. 2, the frame structure of the attachment part of the accelerator operating device 20, the clutch operating device 30, and the change operating device 40 is demonstrated.
Each operating device (accelerator, clutch, change pedal) can be connected to the frame structure 10.
The frame structure 10 is provided with a bar 10W in the left-right direction at the tip of the main frame 10M. Rods 10C and 10D are provided at both ends of the bar 10W via lock mechanisms 10A and 10B.

  The accelerator operating machine 20 is fixedly attached to the tip of the rod 10C. The lock mechanism 10A can be slid in the x and y directions and can be rotated in the Ax, Ay, and Az directions, and can be attached and fixed to the accelerator grip 101R (see FIG. 4) by adjusting the position. ing.

The rod 10 </ b> D is provided with a gripper 32 at the tip thereof, and the gripper 32 </ b> L (see FIG. 4) of the two-wheeled vehicle 100 can be grasped using the gripper 32. Therefore, the rod 10D is fixed by both the lock mechanism 10B and the gripper 32 portion.
In addition, the rod 10D is provided with an attachment portion for the clutch operating device 30 at an intermediate portion thereof, so that the clutch operating device 30 can be attached.

  Similarly, the lock mechanism 10B on the clutch side loosens this and slides the rod 10D in the x and y directions and rotates it in the Cx, Cy and Cz directions, thereby adjusting the position with respect to the grip 101L. Can be fixed.

  The frame 10S is for supporting the torso 51, and can be tilted and locked by the fulcrum 10T. Further, the actuator 10U may be automatically inclined according to the speed.

  As shown in FIG. 3, the left and right lock mechanisms 10 </ b> E can be fixed to the left and right steps 103 </ b> L and 103 </ b> R of the two-wheeled vehicle 50 by a sandwiching method. The lock mechanism 10E can adjust the rotation in the Z direction with respect to the rod 10F.

Further, the rods 10F and 10G can be freely adjusted and locked by a fulcrum 10H.
As shown in FIG. 2B, the rod 10 </ b> F is provided with a mounting portion for the change operating device 40.

  The rods 10G on both sides are connected to the fulcrum 10J, and the rod 10G can be expanded or tightened via the joint 10N by operating an actuator 10K such as a cylinder or a screw that applies a load. Then, the tank of the vehicle is tightened by tightening the rod 10G inward.

  The frame 10L can be adjusted so as to be rotatable in the y direction with respect to the fulcrum 10J, and can be locked. The main frame 10M is rotatable in the y direction with respect to the frame 10L, and can be fixed at an arbitrary angle.

The bar 10W described above is provided at the end of the main frame 10M, and an actuator 10P such as a cylinder or a screw is connected thereto.
When the movable portion 10Q of the actuator 10P is operated by being applied to the rod 10G, a force acts between the bar 10W and the rod 10G, and as a result, the lock mechanism 10E is pressed against the left and right steps 103L and 103R.

  That is, as shown in FIG. 4, when the actuator 10P is operated, the movable portion 10Q at the tip of the actuator 10P extends toward the rod 10G and presses the rod 10G. Then, the lock mechanism 10E connected to the rod 10G is pressed against the step 103L (103R) to be fixed.

A mounting portion for the change operating device 40 is provided at an intermediate portion of the rod 10F. The change operating device 40 can rotate in the Cy direction with respect to the rod 10F and can be set at an arbitrary angle.

The lock mechanism 42 (= 10E) rotates the knob 42c so that the jaws 42a and 42b are closed and fixed to the step 103L.
The attachment 45 of the change pedal 104 is also fixed to the change pedal 104 by closing the jaws 45a and 45b by rotating the knob 45c.

  Since the attachment 45 and the movable portion 43 of the change operating device 40 are connected by the rod 44 and the joint, the change pedal 104 can be operated by moving the movable portion 43 (linear motion).

  As a result, the installation work can be performed quickly, the response and detection sensitivity with each operating unit is good, and it can be used in place of a human, so it can save labor and has a good correlation with the actual driving conditions. A running test device was provided.

  However, with the recent diversification of vehicle types in response to demand for large two-wheeled vehicles, etc., it is necessary to carry out a running test corresponding to these various vehicles. For example, a running test of a scooter type two-wheeled vehicle If a conventional two-wheeled vehicle running test device is mounted when performing the operation, the scooter-type two-wheeled vehicle does not straddle the tank, so that the tank cannot be tightened from the left and right with the rod 10G. Because the end of the neck 53 of the body frame is only placed on the floor of a scooter type two-wheeled vehicle, the adjustment position of the travel test apparatus is shifted due to vibrations etc. accompanying the travel test, and a highly accurate travel test There was a possibility that could not be performed.

  Further, when the end of the neck 53 of the leg frame is placed on the board-shaped step, the change pedal 104 cannot be accurately operated with the end of the neck 53 as a fulcrum due to the vibration described above. There was a fear.

On the other hand, it is costly to separately design and manufacture a vehicular running test apparatus corresponding to each vehicle having a board-shaped or scooter type floor-like step. Further, a separate running test apparatus for each vehicle is required. There has been a problem in that the measurement error between the running test apparatuses occurs.

  The clamper 302 can be moved and fixed with respect to the dummy step 301, and can clamp the scooter floor-shaped step portion 306 between the clamping portions 303a and 303b. When the operation lever 304 is operated in the m direction, the clamper 302 contracts between the holding portions 303a and 303b, holds the side surface of the step portion 306 from the left and right width directions, and is fixed to the floor-like step portion 306 of the scooter. The

  Since the locking mechanism 230 sandwiches the dummy step 301 in the same manner as the locking mechanism 230 located at the bottom of the leg frame (= rod 10F) sandwiches the dummy step 213 in the first embodiment, the locking mechanism 230 sandwiches the dummy step 301. Attached to mechanism 230. Accordingly, the rod 10F (see FIG. 7) is fixed to the step unit 306 via the fixing device 300 and the lock mechanism 230, and can be stably fixed to the scooter.
