Along with the normal rotation... the dial shaft of the lever seat A′ also rotates in the normal direction.
In order to stop, reverse, and stop, the rear part of seat A' is raised, stopped, lowered, and stopped in a continuous manner to test the operation durability of the lifter. At this time, as the rear part of the seat A' moves up and down, the dial shaft 11 below the seat A' tilts. It is mounted on a mounting plate b, and the mounting plate b moves up and down with the forward and reverse rotation of the rotating shaft 7 by the rotating shaft synchronizing cylinder 2, so that the rotating shaft 7 is always on the extension line of the dial shaft 11. is located. Therefore, motor 3
The driving force is transmitted to the dial shaft 11 via the rotary shaft 7, and the lifter A is actuated accurately to move the seat part A.
Move the rear part up and down. When the lifter is operated, the dial shaft 1 of the digital indicator 6a
If the one-rotation set value is set up or down, and the lifter operation goes outside the stroke (outside the set value), the torque is instantly sensed, the motor 3 is stopped, and the direction of rotation of the motor 3 is then reversed. It is configured. Note that the operating torque can be directly read at any time using the digital indicator 6a.

試験を正確に行ない得る。 As described above, the present invention is provided with a buffer mechanism for absorbing the large load that occurs when the motor starts, a torque converter, and a correction mechanism for correcting the misalignment between the lifter's dial axis and the rotation axis between the motor and the chuck. Because of this, the chuck operates properly and the test results are displayed properly. Also, during the test, the lifter's dial axis tilts as the seat moves up and down, but the rotation axis that can be connected and interlocked with the dial axis also tilts.
The rotary axis tuning cylinder provided on the mounting plate allows the dial to tilt on the extension line of the dial axis. Therefore, the rotary shaft moves in accordance with the movement of the dial shaft, and the drive force of the motor is accurately transmitted to the dial shaft via the rotary shaft to operate the lifter, so that the durability test of the lifter can be performed accurately.
