Problems solved by technology

[0005] However, since a specified load is applied to the O-ring during installation in consideration of assembly errors, there is a possibility that the O-ring is attracted to the bearing portion or the opposing surface of the rotating part and the frictional resistance becomes too large, making it difficult to install the O-ring. The problem of getting the specified torque
Therefore, in order to reduce frictional resistance, it has been conceived to apply a lubricant on the opposite surface of the O-ring, but in this case, the O-ring will be damaged due to uneven coating amount or lubricant immersion into the O-ring. Due to the influence of ring expansion and other influences, there is a deviation in the torque, which leads to the problem of unstable operation tactility

Abstract

The invention provides a rotating type electric component which can eliminate friction deviation resulted from an O-shaped ring and stably supply designated torque. The O-shaped ring (17) is clamped by the upper surface of a rotary body (5) and a bearing component (3) opposed to the upper surface of the rotary body (5). A plurality of concentric round groove parts (5C) are formed on the upper surface of the rotary body (5). Thus the flatted O-shaped ring (17) is made not to be attached on the upper surface of the rotary body (5). By the above-mentioned means, the rotary body (5) which is sleekly rotating when friction is generated between the rotary body (5) and the O-shaped ring (17) can stably supply designated torque and make a user obtain excellent operation touches.

Description

technical field [0001] The present invention relates to a rotary electric component that is mounted on, for example, a control panel of an automobile and used, for example, for setting the temperature of an air conditioner. Background technique [0002] Conventionally, an encoder with a push button switch mechanism disclosed in Patent Document 1 is known as a rotary electric component. This encoder includes a storage chamber formed by combining a bearing portion on an upper portion of an insulating case, and a rotating member rotatably operated by an operating member is arranged in the storage chamber. A conductive pattern is buried on the rotating member, and a signal is output by sliding contact with a sliding sub-piece arranged on the insulating case. [0003] In addition, an elastic O-ring such as silicone rubber is sandwiched between the facing surface between the above-mentioned bearing portion and the rotating member, and torque is applied during rotation. [0004] ...
