In other words, the contact portion 54a of the first contact member 54 as the common contact is formed in a ring shape at a position closest to the center C3, and the contact portion 55a of the second contact member is disposed at a second position from the center C3. In addition, the contact portion 56a of the third contact member 56 is disposed at a position closest to the center C3. The rotary body 57 formed of a synthetic resin molded article has an operation portion 57& and a disk-shaped portion. In the mounting portion 57b, the rotating body 57 is housed in the recessed portion 101175.doc 1276131 52a by the mounting portion 57b, and the operating portion 57a is protruded from the hole 53a of the cover 53 and is rotatably guided by the convex portion 52b. The center of rotation of the rotating body 57 is the center C3 of the recess 52a. The annular sliding element 58 formed of a metal plate has one first contact portion 58a and a pair of second and third portions that are asymmetrically disposed on a line passing through the center C4 thereof. The contact portion 58b, 58c° is mounted on the mounting portion 57b in a state where the center C4 and the center C3 which is the center of rotation of the rotating body 57 are attached, and the first sliding member 58 is rotated. The second and third contact portions 58a, 58b, and 58c are each slid to the first The second and third contact portions 54a, 55a, and 56a constitute a conventional rotary electronic component. (For example, refer to Patent Document i) However, the conventional rotary electronic component is the first, second, and third sliding members 58. The contact portions 58a, 58b, 58c are asymmetrically disposed on the line passing through the center C4 while being mounted on the mounting portion 57b in a state in which the center C4 of the sliding member 58 coincides with the rotation center C3 of the rotating body 57, thereby generating the sliding member 58. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The first, second, and second contacts 4 5 8 a, 5 8 b, and 5 8 c of the element 58 are asymmetrically disposed on the line passing through the center c 4 while rotating the center C4 of the sliding member 58 and the rotating body 57.

Thus, the present invention is directed to providing a directional type electronic component on the mounting of the sliding member. . Rotation of the erroneous attachment of the movable member [Summary of the Invention] The first solution to the above problem is to provide a housing having a rotating body and a first mounting on the housing. a sliding element composed of a metal poetry-eighth total plate that is physically and slidably connected to the second dipole 2 conductor; the i-th and second-conducting conductors are disposed not to have a rotation center from the rotating body The sliding element has a pair-moving-two-pair 苐1 and a second contact portion disposed on a line passing through the center thereof, and the sliding member is loaded on the above-mentioned/monthly X-piece, and the two-conductor of the rotating towel core is/ At the same time, the second contact portion of the electric body is slidably attached to the fourth class, and the second means is a second means for solving the configuration of the sliding element, and the second and second contact portions are formed on a part of the ring. The upper side of the element is the third means for solving the problem, and the configuration is such that the first and second contact portions are slidably disposed in the rotating body mounting portion. Further, as a fourth means for solving the above-described sliding element, the rotary electronic component of the present invention has a configuration in which the mounting portion is disposed on a line of a core. 'The structure is equipped with a housing that can be rotated 101175.doc 1276131 with % swivel, the first and second conductors mounted on the housing, and mounted on the rotating body and slid over the first and The first and second electric conductors of the 'moon element' composed of a metal plate of the electric conductor are respectively disposed on a circumference having a different radius from the center of rotation of the rotating body; the sliding element has a symmetry disposed on the line passing through the center At least one pair of the second contact portions of the position, while the sliding jaw is offset from the center of rotation at the center of the sliding member, and is mounted on the rotating body 'with the rotation of the rotating body'! The contact portion is slidably coupled to the electric field correcting body, and the second contact portion is slidably coupled to the second electric conductor. In other words, the position of the sliding element having the first to second contact portions disposed at the symmetrical position on the line passing through the center is offset from the center of rotation of the rotating body, and is mounted on the (fourth body). The i-th contact portion is slidably coupled to the second conductor. Since the second contact body is in the opposite direction to the (four) contact portion, each of the first contact portions is also slidably attached to the first and second electric conductors, so that there is no restriction (mounting direction) in the mounting direction of the sliding member. The mounting work is simple 'there is no slip element error. The installer is different. The sliding element is formed in a ring shape, and the second contact portion is formed on the %-portion portion. Therefore, a large (four) large sliding element can be obtained. In addition, the 'monthly 胄 胄 Between the first and second contact parts, it is said that there is a pair of Anro installed on the swivel "mail m »1 Λ. ^ 疋The installation strength is strong, because "enough to get In addition, the sliding member is disposed on the rotating body, and the mounting portion is disposed at the center of the sliding member through the center of the sliding member. Therefore, the mounting position is correct. The sliding member can be obtained. 101175.doc 1276131 BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of a main portion of a rotary electronic component of the present invention, FIG. 2 is a plan view of an insulating substrate of a rotary electronic component of the present invention, and FIG. 3 is a view showing the present invention.
