PURPOSE:To obtain a shifter capable of shifting an object by the driving force converted from oscillation in optional direction and besides freely of conversion of the direction of shifting, by constituting it such that the direction of the driving force that a driving force converter converts can be reversed freely. CONSTITUTION:For a shifter, four pieces of parallel bases 11a,...11d are arranged so that each topside 12a...12d may be oscillated vertically, and four pieces of blades for reversing the direction of shifting are made so that the set of blades 14a and 14d and the set of 14b and 14c may be reverse in the direction of inclination. And, in case of shifting a mover 13 right, the set of the base bodies 11a and 11d corresponding to the blades 14a and 14d, which generating the rightward driving force, are oscillated by an oscillation means, and the other set of base bodies 11b and 11c are left unoscillated. On the other hand, in case of shifting the mover 13 left, conversely the base bodies 11b and 11c are oscillated to stop the oscillation of the base bodies 11a and 11d. As a result, the mover 13 is shifted right and left. |
