<p><P>PROBLEM TO BE SOLVED: To provide a rotary electronic component which does not generate uneven torque when a rotary body rotates, is difficult to have noise in an electrical output, and reinforces falling-off prevention strength of the rotary body and pressed fracture prevention strength. <P>SOLUTION: A rotary electronic component comprises: a case 10; a rotary body 50 comprising a shaft part 53 projecting from an upper surface of a rotary main body part 51 housed in a rotary body housing recessed part 13 in the case 10; and a cover 130 covering an upper part of the case 10 which houses the rotary main body part 51. The rotary body 50 is axially supported in a freely rotatable manner only by a shaft support part 135 in the cover 130. An entire surface of the rotary main body part 51 which is opposed to an inner bottom surface of the rotary body housing recessed part 13 (surface of a flexible circuit board 30) in the case 10 is installed separately from the inner bottom surface by mounting a case mounting part 55 projecting from an outer periphery of the rotary main body part 51 on a rotary body mounting part 25 provided around the rotary body housing recessed part 13 in the case 10. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
