PROBLEM TO BE SOLVED: To provide a direct advance movement mechanism capable of generating large thrust, maintaining movement straightness of a moved body with high accuracy, and transmitting direct advance movement.SOLUTION: The direct advance movement mechanism 1 comprises:a motor 11(a driving source)which driving by rotating;motion conversion means 2 for converting rotation motion of the motor 11 into direct advance motion and transmitting to a feed screw 12(a reciprocating moving body);and a moved plate 31(a moved body)which is moved by thrust of the feed screw 12.Between the feed screw 12 and the moved plate 31, a thrust transmitting part 5 for transmitting thrust in direct advance direction and a whirling absorption part 6 for absorbing whirling generated on the feed screw 12 are connected in parallel. |
