Abstract
An electric parts unit is located between a pair of holders formed inside surface of a jointing portion of a frame of an assembly. When the assembly is inserted into a cylinder, a projection(s), which is on an outer surface of the jointing portion and has relation to the positions of the holders, is (are) pressed by an inner surface of the cylinder so that the jointing portion bends inward and the holders hold the electric parts unit. Therefore, even if the probe is used under a quaking condition, the electric parts unit will not be quaked so that any noise will not be produced.
