ROLLING GUIDE DEVICE AND OPENING AND CLOSING MECHANISM
A stable guiding operation is performed. A rolling guide device 10 includes a track member 11 including a mounting surface portion 12 and a pair of wall portions 13, 14, and a plurality of first rolling elements 31 rollably disposed inside a space 15 surrounded by the mounting surface portion 12 and the pair of wall portions 13, 14 included in the track member 11. Rolling element rolling surfaces 13a, 14a that are in contact with rolling element outer circumferential surfaces of the first rolling elements 31 are formed at respective wall surfaces of the pair of wall portions 13, 14, the wall surfaces facing each other, the rolling element rolling surfaces 13a, 14a formed at the pair of wall portions, respectively, are each formed as a circular arc groove including a single circular arc, to allow each of the first rolling elements 31 and the corresponding one of the rolling element rolling surfaces 13a, 14a to be in contact with each other at one point, and a moving member 21 includes a second rolling element 41 that rolls in contact with an outer end portion 14b of one wall portion of the pair of wall portions 13, 14 included in the track member 11.
