The present application relates to a runout detection device, which includes a base plate, lateral plates, guide sleeves, springs and dial gauges, etc. During the operation, the sliding sleeve and the lateral dial gauge are moved along the sliding groove in the lateral formwork, so that the runout of right end of the work piece may be measured. The bottom plate of the lower end measuring device is placed above the base plate, the ball at the top end of the probe is always in contact with the lower end of the work piece under the action of the upper spring, the probe is pressed down when contacting a projection, and the L-shaped plate is rotated clockwise through the head nail, at this time, the runout of the lower end of the work piece may be known by the reading of the lower dial gauge.
