PROBLEM TO BE SOLVED: To expedite high acceleration capability by performing weight balancing with a spring for reciprocating a table in a vertical direction when a bed is vertically set in a slide device. SOLUTION: This slide device includes: the bed 1, the table 2 which can reciprocate relative to the bed 1, a field magnet 20 formed from magnets 21 which are parallelly provided at the table 2 so that the polarities may be alternately different in a traveling direction of the table 2, an armature assembly body 15 formed from a coreless and flat armature coil 16 which faces the field magnet 20 and is disposed at the bed 1, and the coil-type spring 5 crossed over between the bed 1 and the table 2. The spring force of the spring 5 constantly supports the table 2 over an effective stroke S of the table 2 to the bed 1. COPYRIGHT: (C)2008,JPO&INPIT
