A rolling guide device comprising: a track member that is a long member extending in a longitudinal direction, the track member including a mounting surface portion that serves as a base for mounting to an external member and a pair of wall portions provided in such a manner as to stand from respective opposite end portions of the mounting surface portion toward one side; a moving member installed in such a manner as to be capable of reciprocating movement along the longitudinal direction of the track member ; and a plurality of first rolling elements rollably disposed inside a space between the track member and the moving member , the space being surrounded by the mounting surface portion and the pair of wall portions included in the track member , to guide reciprocating movement of the moving member relative to the track member , wherein a rolling element rolling surface that is in contact with a rolling element outer circumferential surface of a first rolling element from among the first rolling elements is formed at each of respective wall surfaces of the pair of wall portions , the wall surfaces facing each other, the rolling element rolling surfaces 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 and the corresponding one of the rolling element rolling surfaces to be in contact with each other at one point, and the moving member includes a second rolling element that rolls in contact with an outer end portion of one wall portion of the pair of wall portions included in the track member . a track member that is a long member extending in a longitudinal direction, the track member including a mounting surface portion that serves as a base for mounting to an external member and a pair of wall portions provided in such a manner as to stand from respective opposite end portions of the mounting surface portion toward one side; a moving member installed in such a manner as to be capable of reciprocating movement along the longitudinal direction of the track member ; and a plurality of first rolling elements rollably disposed inside a space between the track member and the moving member , the space being surrounded by the mounting surface portion and the pair of wall portions included in the track member , to guide reciprocating movement of the moving member relative to the track member , wherein a rolling element rolling surface that is in contact with a rolling element outer circumferential surface of a first rolling element from among the first rolling elements is formed at each of respective wall surfaces of the pair of wall portions , the wall surfaces facing each other, the rolling element rolling surfaces 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 and the corresponding one of the rolling element rolling surfaces to be in contact with each other at one point, and the moving member includes a second rolling element that rolls in contact with an outer end portion of one wall portion of the pair of wall portions included in the track member . <EOS>
