請求項１記載の電子時計の構造。[Claims for Utility Model Registration] (1) A base frame and a receiving member for supporting and accommodating a power source, circuit means, electrostrictive converting means, gear train means, etc., and the electrostrictive converting means has a concave cross section. The gear train means includes a stator that fixes a piezoelectric vibrator to the outer bottom surface of the recess and generates a traveling wave, and a disk-shaped rotor that presses against the rib end surface of the recess, and the gear train means rotates the rotor. In an electronic watch consisting of a deceleration gear train that decelerates and a pointer wheel train that displays the pointer, one shaft member fixed to the base frame bears and supports the deceleration gear train, and the other supports the pointer wheel. A structure of an electronic timepiece characterized by a structure in which columns are supported by bearings. (2) The structure of an electronic timepiece according to claim 1, wherein the rotor is pivotally supported by an opening formed in the center of the shaft member.
