Alignment adjusting mechanism and measuring instrument

A measuring instrument, comprising:

• an adjusting plate having a first adjustment end and a second adjustment end which are parallel to each other in a first direction;
• a probe fixing portion integrated with the adjusting plate;
• a probe that is fixed to the probe fixing portion and that has a shaft and a stylus formed on a tip of the shaft;
• a base that is connected with a measuring instrument body and that has a first base end and a second base end which are parallel to each other in the first direction;
• an inclination adjuster that presses the adjusting plate in a direction parallel to a planar direction of the adjusting plate and substantially in a second direction orthogonal to the first direction;
• adjustment connectors that respectively connect the first adjustment end with the first base end and the second adjustment end with the second base end;
• and
• a measuring unit that detects a position of the stylus when the stylus is in contact with an object to be measured to measure a profile of the object, wherein
• the base is connected with the measuring instrument body while a displacement of the base in the second direction is restricted, and
• the stylus is disposed on a line of intersection of:
• a first inclined surface including the first adjustment end of the adjusting plate and the first base end of the base;
• and a second inclined surface including the second adjustment end of the adjusting plate and the second base end of the base, when the adjusting plate is not pressed by the inclination adjuster.
