A translational movement device (10), in which a moving part (43) moves reciprocally while maintaining a parallel attitude, comprises: elastic parts (41, 42); a fixed part (44); a moving part (43); and a drive receiving part (45M) which is attached to the moving part (43) and moves reciprocally together with the moving part (43) by receiving an electromagnetic force in a non-contact manner. The elastic parts (41, 42) and the moving part (43) constitute a parallel leaf spring structure (40) having one end (40a) secured to the fixed part (44). The drive receiving part (45M) receives the electromagnetic force such that the moving part (43) of the parallel leaf spring structure (40) oscillates at a resonant frequency. It becomes possible to improve the translational movement of the moving part in a case where the parallel leaf spring structure is caused to oscillate at the resonant frequency thereof. |
