PROBLEM TO BE SOLVED: To avoid leakage of a viscous liquid contained in a container from a bearing.SOLUTION: An eddy-current type instrument comprises: an inductor that is rotated by the action of eddy currents generated by rotation of a magnet; a pointer rod 17 to which a pointer is attached and that is rotated together with the inductor around an axis A; a container 50 that is attached to the pointer rod 17 and contains a viscous liquid S therein; and a bearing 60 that receives the pointer rod 17. The container 50 has a bottom 51 through which the pointer rod 17 penetrates and a first cylinder 52 that extends along the axis A from the bottom 51 toward the pointer. The bearing 60 is provided in the first cylinder 52 at the pointer side and has a second cylinder 62 that is put in the viscous liquid S contained in the container 50. In the container 50, an inclined plane 53 is formed. The inclined plane 53 connects an inner peripheral surface 52a of the first cylinder 52 and the bottom 51, and is inclined toward the axis A from the inner peripheral surface 52a.SELECTED DRAWING: Figure 2

    【課題】収容体に収容された粘性液体が軸受部から漏れ出すことを抑制する。【解決手段】渦電流式計器は、磁石の回転により発生する渦電流作用によって回転する誘導体と、指針が取り付けられ、誘導体と共に軸線Aを中心に回転する指針軸17と、指針軸17に取り付けられて内部に粘性液体Sを収容する収容体50と、指針軸17を受ける軸受部60と、を備える。収容体50は、指針軸17が貫通する底部51と、底部51から軸線Aに沿って指針側へと延びる第1筒状部52と、を有する。軸受部60は、指針側から第1筒状部52の内部に到ると共に、収容体50に収容された粘性液体Sに浸る第2筒状部62を有する。収容体50の内部には、第1筒状部52の内周面52aと底部51とを繋ぐ傾斜面53であって、内周面52aから軸線Aに向かって傾斜する傾斜面53が形成されている。【選択図】図2
