本考案は可変抵抗器、詳述するなら箱形ケースの側面部
に取付けた複数の可変抵抗器を、ケースに傾斜自在に取
付けた作動杆により任意に操作ができるようにしたジョ
イステックタイプの可変抵抗器の改良構造に関する。[Detailed description of the invention] This invention is a variable resistor, or more specifically, a plurality of variable resistors attached to the side of a box-shaped case, which can be operated arbitrarily by an operating rod attached to the case so as to be tiltable. This invention relates to an improved structure of a joystick type variable resistor.
最近この種の可変抵抗器においては作動杆に取付けるボ
ールの材質をコストを安くする目的で金属から絶縁材に
変えている。Recently, in this type of variable resistor, the material of the ball attached to the operating rod has been changed from metal to an insulating material in order to reduce costs.
しかしこの場合、作動杆を取付けたボールを絶縁材で成
型したものにあっては、金型で精度の高い円心が出す、
従って完全な球面体を得ることができないため、ボール
の回動が不安定になるという欠点があった。However, in this case, if the ball with the operating rod is molded from an insulating material, the mold will produce a highly accurate center of the circle.
Therefore, since a perfect spherical body cannot be obtained, there is a drawback that the rotation of the ball becomes unstable.
加えて、ボールの支承部の精度のバラツキが製造上世は
難く、特にボールとその支承部材とを金属と絶縁材との

のためボール10の回転が不安定になって作動杆にぶれ
が生じ、且つ、作動感触も良くないという欠点があった
。In addition, variations in the accuracy of the ball bearing part are difficult in manufacturing, especially when the ball and its bearing parts are made of different materials, such as metal and insulating material, due to differences in expansion coefficient due to temperature. Taking these into consideration, it is necessary to set a certain amount of clearance between the ball and the member that supports it, which may cause the rotation of the ball 10 to become unstable, resulting in vibrations in the operating rod, and The drawback was that it did not have a good feel.
