According to such a configuration, in the conventional shift fork test apparatus, when a predetermined load is applied in one direction through the bar 110, the load is applied to the pair of pads 12 through each column 125. The load applied to each pad 12 deforms the arm 11 of the shift fork.

When the arm 11 is deformed by a load, the bar 110 is moved to correspond to the deformation amount, and the movement amount of the bar 110 is measured by the gauge 130 and applied to deform the arm 11. The value of the losing load is also measured by the load cell 120.

However, although the deformation amount of the pad 12 of the shift fork 10 is differently generated due to the torsion caused by the slide movement of the arm 12, it is impossible to measure the actual deformation amount of the two side pads 12 according to the structural load. There is this.

In addition, since the column 125 is in contact with the pad 12, there is a possibility that slip occurs, so that the reliability of measuring the deformation amount is further lowered.
