Abstract
Provided is a drive mechanism capable of withstanding sterilization treatment using a sterilization gas such as hydrogen peroxide and capable of performing positioning operation with heightened accuracy. In a drive mechanism according to the invention, a movable block disposed in the internal space of a partition wall for blocking a sterilization gas is coupled to a movable platform disposed in the external space of the partition wall by means of a magnet coupling mechanism. Further, biasing magnet units are disposed on surfaces, of the movable block and the movable platform, on which no magnet coupling mechanism is disposed, such that the biasing magnet units serve as magnetic poles repelling each other. Repelling force generated by the biasing magnet units serves as biasing force that biases the movable platform toward the partition wall.
