A ball connecting body for a ball screw or a linear guide-way, comprises
spacers, guide linking members, and connecting members. The spacers are
interposed between two adjacent balls, thereby preventing the two balls
from hitting. The guide linking members are used for linking the two
spacers, so that the ball may be maintained in a space formed by the
guide linking members and the spacers. The connecting member connects two
adjacent spacers. The total width of the connecting member in a direction
of a connecting line of the two guide linking members is smaller than the
total height of the connecting member in a direction vertical to the
connecting line of the two guide linking members, so that the connecting
member has an excellent bendable capability in the direction of the
connecting line of the two guide linking members.
