The operating member 57 is attached by fitting the regular hexagonal spherical body portion 57d on the shaft body 57b side into the through hole 54a of the rotating body 54 from the insulating base 51 side and holding the shaft body 57c in the housing 56a. The operating member 57 is located on the horizontal line Z2 with a coil spring 58 interposed between the shaft body 57c and the housing 56a. Accordingly, the operation member 57 can perform a rotating operation and a tilting operation with the contact portion of the regular hexagonal sphere portion 57d with the rotating body 54 as a fulcrum.

In the conventional multidirectional input device having such a structure, when the operating portion 57a of the operating member 57 is rotated, the rotating body 54 is rotated by the regular hexagonal spherical portion 57d of the shaft 57b, and the contact piece 52 is slid.

[0010]

In the conventional multidirectional input device, since the regular hexagonal spherical portion 57d performs a circular motion, the fitting of the regular hexagonal spherical portion 57d into the through hole 54d is loose. When rotated, the regular hexagonal spherical part 57d
Between the and the rotating body 54, play occurs in the rotating direction,
There is a problem that the rotation of the operation member 57 cannot be transmitted to the rotating body 54 immediately. In addition, the repetition of the tilting operation of the operation member 57 causes abrasion between the regular hexagonal sphere portion 57d and the rotating body 54, thereby increasing the play in the rotating direction and further increasing the rotation of the operating member 57. 54 cannot be transmitted immediately.

Next, when the pressing of the operating member 18 is released,
The shaft 18d is returned to the original state by the biased push button 17, the operation member 18 and the rotating body 8 are returned to the original horizontal state, and the push switch 15 is also returned to the original state. Contact switching is performed. When the operation member 18 is tilted, the shaft 18d is guided by a vertical groove (not shown) provided in the case 19 so that the shaft 18d can be accurately moved downward. Thus, the operation of the multidirectional input device of the present invention is performed.

In the above-described embodiment, the tilting operation of the rotating body 8 has been described as performing the tilting operation using the insulating base 1 as a supporting member. However, the mounting plate 12 or another member is supported by the supporting member. May be used for

According to the multidirectional input device of the present invention, the shaft 18
When the operating member 18 is tilted in a direction perpendicular to the axial direction G2 of c and 18d, the rotating body 8 performs a tilting operation together with the operating member 18, and the push switch 15 is operated by the operating member 18, so that the shaft The body 18c and the hole 8f of the rotating body 8 can be fitted in a state where there is no play in the rotating direction, so that the rotation of the operating member 18 can be immediately transmitted to the rotating body 8, and the operation is reliable and the precision is improved. And a good multidirectional input device can be provided. Further, there is no wear between the hole 8f and the shaft 18c due to the rotation of the regular hexagonal sphere as in the related art, and accurate rotation transmission can be performed for a long time.

Further, since the hole 8f of the rotating body 8 and the shaft 18c of the operation member 18 are fitted without any gap, a more reliable operation and a more accurate multi-directional input device can be provided. In addition, the rotary electric component D1 has a support member for causing the rotating body 8 to perform a tilting operation. When the operating member 18 tilts, the rotating body 8 comes into contact with the supporting member. Since the rotating body 8 performs the tilting operation, the structure is simple, and a reliable tilting operation of the rotating body 8 can be obtained.

Further, since the supporting member is formed by the insulating base 1 or the mounting plate 12 which constitutes a part of the rotary electric component D1, the number of components is small, and the inexpensive and compact rotating body 8 is provided. A configuration capable of tilting operation is obtained. The support member is formed of an insulating base 1 that forms a part of the rotary electric component D1. The insulating base 1 has a hole 3b for loosely fitting a shaft 8a provided on the rotating body 8. , Operation member 18
During the tilting operation, the shaft 8a comes into contact with the side surface forming the hole 3b, and the rotating body 8 performs the tilting operation. Therefore, the structure is intermediate, and the tilting operation is performed at a position far from the operation unit 18a. A fulcrum is formed, so that the rotating body 8 has a small inclination and good contact of the contacts can be obtained.

Further, the rotary electric component D1 has a mounting plate 12, which has a cylindrical portion 12h located in the rotating body 8, and a shaft 18c of the operating member 18 is mounted on the mounting plate 12.
Since the shaft body 18c is fitted into the non-circular hole 8f of the rotating body 8 while being inserted into the cylindrical portion 12h from the side, the shaft body 18c can be inserted by guiding the cylindrical portion 12h, and the assemblability is good. At the same time, the shaft body 18c is fitted in the hole 8f in a substantially horizontal state by the cylindrical portion 12h, so that the hole 8f or the shaft body 18c is less damaged during assembly.

The rotating body 8 has a cylindrical holding portion 8b, and a code pattern extending in the axial direction G1 is provided on the outer peripheral portion of the holding portion 8b. The contact piece 6 arranged in a direction perpendicular to the direction G1 is slid, so that the contact position of the code pattern on the contact piece 6 only moves downward, and the contact state between the two can be reliably maintained. Can be provided.
