C. 2. Description of the Related Art Generally, a power vehicle is tested by using a drive simulator including a hydraulic or electric actuator and an automatic driving device so as to be completely equivalent to a person traveling on an actual road. It is common practice to operate a mission and a brake and automatically drive an arbitrary traveling pattern on a chassis dynamometer.

Conventionally, in a drive simulator, there is a mission operation unit for operating a shift lever, as illustrated in FIG.

The mission operating unit 1 is used by being installed on the floor 3 of the power vehicle 2, and includes an actuator unit 4 and a chucking device unit 5. The chucking device unit 5 includes a push-pull solenoid 6 as a drive source, which is to be connected to the actuator unit 4, and a grip claw portion 8 attached to the push-pull solenoid 6 via an interlocking mechanism unit 7. Then, in conjunction with the driving operation of the push-pull solenoid 6, the pair of claws 8a,
8a is opened and closed so that the shift lever 9 can be grasped, and the rotation shaft support portion 7a of the interlocking mechanism portion 7 rotates a predetermined angle around the x axis extending in the longitudinal direction of the chucking device portion 5 in FIG. It is movable.

The mission operating unit 1 configured in this manner grips the shift lever 9 installed on the floor 3 by the chucking device unit 5 and drives and controls the actuator unit 4 in this state to perform a required shift change operation. After completing the operation of moving the shift lever 9 to the predetermined position in each position such as the first speed and the second speed, open the chucking device section 5 and shift the gear of the transmission without applying excessive force. The operation is performed by releasing the lever 9 to bring the lever 9 into an independent state.

In such a shift operation, the shift lever 9 causes tilts in the x-axis and y-axis directions in FIG. 2 which are tilts between the shift direction and the select direction at each position. The tilt around the y-axis is absorbed by the rotating operation of the interlocking mechanism unit 7, and the tilt around the y-axis is a pair of claws 8.
The shape of the gripping surface concave portions of a and 8a is made to have a play having a function of absorbing this inclination so that the operation can be performed without any trouble.

D. DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the conventional mission operating section 1 as described above, the interlocking mechanism section 7 is provided with a mechanism for operating the pair of claws 8a, 8a, and therefore the rotation angle is limited in terms of the mechanism structure. There is. For this reason, when the power vehicle is diversified and the operating range of the shift is widened as in recent years, the rotation angle of the interlocking mechanism portion 7 cannot sufficiently follow the inclination of the shift lever 9 around the x-axis at each position. Then, there was a problem that it could not be operated.

Further, in order to increase the rotation angle of the interlocking mechanism portion 7 about the x-axis, the structure becomes large and the weight thereof increases. Therefore, the actuator portion for driving the chucking device portion 5 is operated. 4 is also inconvenient because a large load is applied to the control performance and the control performance deteriorates, and there is also a problem that it may not be installed in a narrow vehicle due to too much space.

The present invention has been made in view of the above points, and an object of the present invention is to newly provide a chucking device which can cope with a large inclination of each position of a shift lever, and which is small, lightweight and easy to handle.

E. Means for Solving the Problems The chucking device for a drive simulator according to the present invention is
The main casing is pivotally attached to the free end of the support rod attached to the actuator part, and the respective root ends of the pair of operating rods are pivotally attached to the main casing at positions separated by a predetermined distance. At the positions near the free ends of the operating rods, pivot pins are attached to the shaft pins of a pair of claws that hold the shift lever from both sides, and springs that bias the operating rods in the mutually opening direction. Installed, one end of the outer wire is fixed to one of the operating rods, one end of the inner wire is fixed to the other operating rod, and the other ends of the outer wire and the inner wire 14 are relatively pulled and changed. It is characterized in that it is configured to be connected to a source.

F. Operation With the above-mentioned configuration, the inner wire is relatively pulled by the drive source, the pair of operating rods are interlocked and interlocked, the shift lever is sandwiched, and the pulling force of the drive source is increased. Then, the pair of operating rods are opened by the biasing force of the spring to release the shift lever.
Further, the tilting of the shift lever is absorbed by the free rotation of the pivots of the claws and the free rotation of the pivot of the main casing, so that the tilting of the shift lever can be naturally followed. Has the effect.
