Claims

[Scope of utility model registration request]

Locking holes are drilled at predetermined intervals in a master pole that supports the master arm of a master & slave type robot, and the locking holes are fixed to the base end of the master arm and fitted onto the master pole so as to be able to slide vertically. The tip of the plunger is fitted and locked into a desired hole of the master pole by the spring force on the side of the boss, and when the knob is pulled against the spring force, the tip comes out of the hole. A master arm height positioning mechanism comprising a spring plunger whose engagement is released.
