Abstract:
1. A probe, comprising: a force sensor that detects a measuring force generated when the probe contacts with a workpiece and outputs the measuring force as a force detection signal; a position detector that detects a measuring position of the workpiece detected by the force sensor and outputs the measuring position as measuring position information; a relative moving section that relatively moves the force sensor and the workpiece; a probe body that is held by the relative moving section; a sensor module to which the force sensor is attached; and a fixing member that is inserted to the sensor module and the probe body, the fixing member detachably positioning and fixing the sensor module to the probe body, wherein the probe body includes a substantially planar first positioning portion, a second positioning portion that is formed upright on the first positioning portion and an engaging hole that is provided to the first positioning portion, the engaging hole allowing the fixing member to be inserted thereinto and engaged therewith in a detachable manner, the sensor module includes a slidable-contact portion that slidably contacts with the first positioning portion, a pressing portion that is pressed against the second positioning portion and an insertion hole that communicates a slidable-contact portion side and a side opposite to the slidable-contact portion side, the insertion hole allowing the fixing member inserted thereinto, the fixing member includes: a rod-like portion that is formed in a rod-like shape and inserted into the insertion hole, an end side of the rod-like portion engaged with the engaging hole; and a fixing projection that protrudes from a lateral surface of the other end side of the rod-like portion, and the insertion hole includes an inclined portion on which the fixing projection can abut, the inclined portion inclined such that a distance between a pressing portion side of an opening positioned opposite to the slidable-contact portion and the pressing portion becomes gradually larger toward the slid-contacting portion, the insertion hole having a diameter larger than that of the rod-like portion.
