Abstract
In a linear guide apparatus, a rolling-element accommodation belt 50 is incorporated into each of endless circulation passages. This rolling-element accommodation belt 50 is formed into a shape having ends and has a plurality of rolling-element accommodation sections for individually accommodating balls 46. Of the rolling-element accommodation sections, first rolling-element accommodation sections 55A located at the respective end sections are formed so as to constrain movement of a spacer section 59 located at the end section toward the outer periphery side of an endless circulation passage by means of the ball 46 accommodated in the spacer section. Second rolling-element accommodation sections 55B other than the first rolling-element accommodation sections are formed so as to enable removable accommodation of the balls 46 to be accommodated toward the inner periphery side of the endless circulation passage.
