OIL LEAK PREVENTING DEVICE FOR ROD-SHAPED MEMBER

摘要

PROBLEM TO BE SOLVED: To prevent a lubricating oil from being leaked from a combined movement part in a rod-shaped member to perform the combined movement of sliding in the axial direction and in a direction crossing the axial direction. SOLUTION: The rod-shaped member to perform the combined movement of reciprocating in the axial direction and reciprocating in the direction crossing the axial line while being linked with the main shaft of a sewing machine, is provided with a plate-shaped oil thrower member formed with a hole to which the rod-shaped member is fitted and allowing the axial movement of the rod-shaped member, and a guiding member for blocking the movement of the oil thrower member in the axial direction of the rod-shaped member and allowing the movement of the oil thrower member in the direction crossing the axial line of the rod-shaped member.
