Rolling guide device

A rolling guide device, comprising:

• a track member that is an elongated member extending in a longitudinal direction, the track member being formed by:
• an attachment surface portion serving as an attachment reference with respect to an external member;
• and
• a pair of wall portions installed upright toward one side from each of both ends of the attachment surface portion;
• a moving member installed to be movable in a reciprocal manner along the longitudinal direction of the track member;
• and
• a plurality of rolling bodies that guide a relative reciprocal movement of the moving member with respect to the track member by being rollably disposed in a space surrounded by the attachment surface portion and the pair of wall portions forming the track member and between the track member and the moving member, wherein:
• a rolling-body rolling surface that comes into contact with a rolling-body outer circumferential surface of each of the rolling bodies is formed in each of wall surfaces of the pair of wall portions facing each other;
• a scraper including a pressing portion corresponding to each of the rolling-body rolling surfaces, wherein the scraper is turnably installed in the moving member, and each pressing portion presses corresponding one of the rolling-body rolling surfaces;
• the scraper includes at least:
• an attachment portion turnably attached to an attachment shaft formed in the moving member;
• and
• a frictional force of each pressing portion with respect to the rolling-body rolling surface is smaller than a frictional force of the attachment portion with respect to the attachment shaft formed in the moving member.
