ROTARY ELECTRONIC COMPONENT

PROBLEM TO BE SOLVED: To provide a rotary electronic component which can stably support a wiper and a rotating body which are stored in a case.SOLUTION: A rotary electronic component comprises: a circuit board built-in case 10 in which a circuit board 50 is insert molded in a case 20 and a sliding-contact pattern 53 of the circuit board 50 is exposed on a bottom face of a rotating body storage recess 21 provided in the case 20; a rotating body 90 to which a slider 70 is attached; and a middle terminal organizer 120 having a shaft 123 and a middle terminal 125. The case 20 has a slider support protrusion 23 which protrudes on the top face side through a substrate through hole 54 provided on the circuit board 50 and which is integrally formed with the case 20 in the rotating body storage recess 21. A shaft insertion through hole 25 is provided at the center of the slider support protrusion 23. The rotating body 90 with the slider 70 being attached is stored in the rotating body storage recess 21; and the slider 70 is mounted on the slider support protrusion 23; a tip of the shaft 123 inserted in the shaft insertion through hole 25 is inserted in a through hole 73 provided on the slider 70 and the tip is swaged thereby to support the rotating body 90 and the slider 70 in a rotatable manner.SELECTED DRAWING: Figure 5 【課題】ケース内に収納する摺動子及び回転体を安定性良く支持できる回転式電子部品を提供する。【解決手段】回路基板５０をケース２０内にインサート成形し、その際ケース２０に設けた回転体収納凹部２１の底面に回路基板５０の摺接パターン５３を露出した回路基板内蔵ケース１０と、摺動子７０を取り付けた回転体９０と、軸部１２３と中端子１２５とを有する中端子形成体１２０とを具備する。回転体収納凹部２１内に、回路基板５０に設けた基板貫通孔５４を介して上面側に突出する摺動子支持突部２３をケース２０と一体に成形する。摺動子支持突部２３の中央に軸挿入用貫通孔２５を設ける。回転体収納凹部２１内に摺動子７０を取り付けた回転体９０を収納して摺動子支持突部２３上に摺動子７０を載置し、軸挿入用貫通孔２５に挿入した軸部１２３の先端を摺動子７０に設けた貫通孔７３に挿通してかしめ、回転体９０と摺動子７０を回動自在に支持する。【選択図】図５
