Abstract

PROBLEM TO BE SOLVED: To reduce the time required for the clamping work of an electronic- component attaching band, by correcting simply the upper-side and lower-side positional discrepancies between both the end portions opposed to each other of the main body of the band which are generated in the metallic working thereof. SOLUTION: The side surface of a cylindrically formed electronic-component main body 1' is surrounded by a band-form band main body 1. By opposing to each other both the end portions of the band main body 1, the relative distance between both the end portions is compressed to fasten the electronic- component main body 1' to the band main body 1 in its inside. In this electronic- component attaching band, after making lateral-U-shaped the form of an end portion 20a of the band to use it as a guide portion 23, the distance between both the end portions of the band is compressed to contact them with each other. By this feature, even when there are generated the upper-side and lower- side positional discrepancies between the end portion 20a and the other end portion 20b of the clamping portion of the band, both the end portions can be aligned easily with each other while correcting the positional discrepancies.
