Title:
EDDY CURRENT TYPE INSTRUMENT AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2018/021006
Kind Code:
A1
Abstract:
In order to provide a technique for improving the productivity of an eddy current type instrument having a spiral spring, a spiral spring (60) of this eddy current type instrument (10) comprises a central section (61) fixed to a second rotating shaft (51), and a winding section (62) wound in a helical shape around the central section (61). A lid body (40) of the eddy current type instrument (10) has a fixing section (70) for fixing an end portion (64) of the winding section (62), and the fixing section (70) is formed in a position at which the end portion (64) of the winding section (62) can be pushed back such that a gap between adjacent components in the radial direction becomes wider relative to the natural length of the winding section (62).
