<p>PURPOSE:To downsize a structure and to process a flexible longitudinal body at the internal part by fixing one end part of a circular arcuated flexible longitudinal body to a speed reducer case and the other end part to a 1st housing and inserting them into the insertion holes of the peripheral walls of first and second housings. CONSTITUTION:An annular space 25 is formed coaxially with a speed reducer case 11, integrally and bonded so as to include a speed reducer 10 and 1st housing 21 and at the interval to the external part in the radial direction of the speed reducer case 11 and a first housing 21 and a cylindrical second housing 23 which internal face one end is sealed freely rotatably to the external face of the opposite end to the bonding with the speed reducer 10 of the first housing 21 is provided. The flexible cable 26 arranged in U shape is stored in this annular space 25 and made in a circular arcuated shape along the outer peripheral faces of the speed reducer case 11 and first housing 21. Moreover insertion holes 31, 32 are respectively formed on the peripheral walls of the first and second housings 21, 23 and the flexible cable 26 is inserted into these insertion holes 31, 32 with its extension from the U shaped part.</p> |
