A holding tool for an elongated member includes a connecting member to be attached to an attachment member, a first holding part for holding the elongated member comparatively tightly, and a second holding part for holding the elongated member with a prescribed space therearound. A gap is formed between the first and second holding parts so that the elongated member can move from the first holding part to the second holding part.

Holding tool for elongated member

A torque limiter is formed of a shaft, a cylindrical magnet attached to an outer periphery of the shaft, and a housing for rotationally supporting the axial ends of the shaft and formed of first and second housing portions. A magnetizable member in a cylindrical shape is attached to inner peripheries of the first and second housing portions to thereby form a space between cylindrical portions of the first and second housing portions. The magnetizable member faces an outer periphery of the magnet with a predetermined gap therebetween when the magnet is inserted into the magnetizable member. A ring containing magnetizable materials therein is attached to the space on an outer periphery of the magnetizable member. The ring changes an apparent volume of the magnetizable member, so that torque of the torque limiter is adjusted by selecting a proper ring.
