A structure for connecting a screw shaft 3 and a drive cable 6 in a seat belt positional adjustment device comprises a first joint 16 coupled to the screw shaft 3, and a second joint 28 coupled to the drive cable 6. The connecting ends of screw shaft 3 and drive cable 6 are noncircular in section. The joint 16 includes a cylindrical rotatable member 20 having a noncircular bore 22 to receive the end 14 of the screw shaft 3. The joint 28 includes a cylindrical coupling member 32 having a noncircular bore 36, a holder 30 for the coupling member 32 and a stopper 38 extending radially from the inner periphery of the holder 30 to prevent release of the spring biassed coupling member 32 from the holder 30. The end 12 of the drive cable 6 is inserted into the bore 36 and the coupling member 32 and rotatable member 20 are engaged with each other. Holders 18, 30 for the rotatable member 20 and coupling member 32 have interengaging elements 26, 46 to prevent the first and second joints from being separated from each other. <IMAGE>
