<p>PROBLEM TO BE SOLVED: To provide a positioning mechanism which is easily attachable/detachable and which can reproduce positional relationship with good accuracy, and a positioning method.SOLUTION: A positioning mechanism is for performing positioning between a cylinder block 5 having positioning holes 5b and a measurement jig plate 2 having guide holes 2b corresponding to the positioning holes 5b. The positioning mechanism includes: a first pin 3 which includes a fixing part which is fixed to the positioning hole 5b on one side and an adjustment part which is inserted into the guide hole 2b on the other side, in which a female screw part is formed inside the fixing part, in which a taper part is formed and also a split groove is formed so as to expand in a radial direction inside the adjustment part; and a second pin 4 in which a pressing part, which pushes and expands the adjustment part in the radial direction by coming into contact with a male screw part which is screwed into the female screw part and the taper part, is formed.</p> |
