Abstract
A form measuring apparatus that is provided with a form measuring device that includes a detection device detecting a position on a surface of an object, and a feeding mechanism that moves the form measuring device in an axis direction. The feeding mechanism includes a drive shaft provided so as to be rotatable around an axis; a traction nut that is provided so as to hold the drive shaft from a direction orthogonal to an axis line of the drive shaft, and that also can switch between a frictional contacting state frictionally contacting the drive shaft and a separation state separated from the drive shaft; and a bracket coupling the traction nut and the form measuring device. The bracket is provided with a motor that includes a rotation shaft that is inclined with respect to the axis line, and the motor rotates the drive shaft.
