に行ない得る等の効果を生じる。 As described above, since the variable capacitor of the present invention has a structure in which the terminals of the trimmer capacitor protrude toward the board side, the soldering work can be performed easily by using a solder dip on the printed circuit board. By inserting the board into the opening hole of the case bulge and then pushing the board into the case, the terminals of the trimmer capacitor are bent toward the board by the bulge and protrude toward the board. This eliminates the need for bending and locking the terminals to protrude them to the board side, which improves assembly work efficiency.In addition, the terminals of the trimmer capacitor are covered by the bulge of the case and guided. Therefore, firstly, there is no fear that the terminals of the trimmer capacitor will come off the bulge and jump up, and the terminals can be reliably held in a state protruding from the board side. It is possible to increase the integration density because it can be assembled on a printed circuit board in close proximity to other components without causing electrical problems due to contact with other components, and furthermore, the terminals protruding from the opening holes do not bulge out. Since the position of the variable capacitor is regulated by the part and the opposing part, the positioning accuracy of the tip of the terminal can be improved, but mounting the variable capacitor on the printed circuit board requires troublesome work such as correcting the position of the terminal. This results in effects such as smooth operation without any problems.
