Disclosed a slider unit having built-in a moving-coil linear motor(20) made compact in construction by the provision of an improved magnet yoke(21) for supporting field magnets(30,31), which is made in a slim construction, nevertheless very high in stiffness. The magnet yoke(21) is comprised of a pair of confronting webs(22,23) and a connecting web(24) to connect integrally the confronting webs(22,23) to each other. The magnet yoke(21) of such integral construction helps ensure the overall high stiffness despite the webs being made thin. Thus, the magnet yoke(21) may be made considerably slim, compared with the prior magnet yoke(21) in which the confronting webs (22,23) and connecting web(24) are produced individually. A moving-coil assembly(40) is installed to a table(2) movable in a sliding manner through linear motion guide units(16) with respect to a stationary bed(2). <IMAGE> |
