Abstract

PURPOSE: To reduce a carrying cost due to the possible repeated use of a holder by mounting carrying objects such as a bobbin on a carrier through elastic retaining members which engage detachably with an engagement hole for ensuring easy detachment to the carrier. CONSTITUTION: Each of carriers 2 has a cylindrical through-hole at the suspended position of a bobbin 6, and a large-diameter end 7a of each of carriers 2 makes an opening. The large-diameter end 7a communicates with the intermediate part of each carrier by a taper part. Each of elastic retaining members 8, which is formed by a hollow cylindrical synthetic resin tube sleeve, is housed in a through-hole 7. On one end of each elastic retaining member 8, an outgoing retaining projected bar 9 is formed. A taper face 9a is formed below the retaining projected bar 9. Slots 10 are formed in parallel with an axis on diagonal lines of the four positions of the elastic retaining members 8. To retain a bobbin holder 5 attached to the bobbin 6, it is necessary to simply push downwards the elastic retaining members 8 into the corresponding through-holes 7 from the lower side. As a result, the taper face 9a can be prevented from falling off owing to its connection with the taper face of the surface end 7a.
