A long rod polishing device includes a prismatic or columnar battery, a battery mounting portion, an electric motor, a pad, and a rod portion. The battery is mountable to the battery mounting portion. The electric motor is driven by an electric power from the battery. The pad has a polishing surface and moves by a driving force from the electric motor. The rod portion has an end portion to which the pad is coupled. The battery mounted to the battery mounting portion has a longest side. The longest side has a direction so as to form an angle with respect to a second imaginary straight line. The second imaginary straight line is perpendicular to both of a center axis of the rod portion and a first imaginary straight line. The first imaginary straight line is perpendicular to the center axis and parallel to the polishing surface of the pad.

No: 18/417381 Application Filed: January 19, 2024 Assignees: MAKITA CORPORATION (Anjo-shi, JP) Claim: 1-14. (canceled) Claim: 15. A long rod polishing device comprising: a prismatic or columnar battery; a battery mounting portion to which the battery is mountable; an electric motor driven by electric power from the battery; a pad having a polishing surface, the pad moving by a driving force from the electric motor; a rod portion having an end portion to which the pad is coupled; and a handle portion mounted to an end of the rod portion opposite to the pad, wherein the battery mounting portion is located on the handle portion, the battery has a long side that is longest of all sides of the battery and the long side forms an angle with respect to a second imaginary straight line when the battery is mounted, the second imaginary straight line is perpendicular to both of a center axis of the rod portion and a first imaginary straight line, and the first imaginary straight line is perpendicular to the center axis and parallel to the polishing surface of the pad, the long side of the battery mounted to the battery mounting portion is parallel to the center axis of the rod portion, the rod portion is thinner and longer than the handle portion, and the pad is configured to change its posture around an axis parallel to the first imaginary straight line. Claim: 16. The long rod polishing device according to claim 15, wherein a plurality of the batteries are mountable to the battery mounting portion. Claim: 17. The long rod polishing device according to claim 15, wherein the electric motor and the pad are held to a head portion housing, and the pad is configured to change the posture around the axis parallel to the first imaginary straight line via the head portion housing. Claim: 18. The long rod polishing device according to claim 15, wherein the handle portion includes a dust collection hose coupling portion to which a dust collection hose is connectable. Claim: 19. The long rod polishing device according to claim 18, wherein the battery mounting portion is closer to the pad in a direction of the center axis of the rod portion than the dust collection hose coupling portion is. Claim: 20. The long rod polishing device according to claim 15, wherein the battery is slidably mounted to the battery mounting portion. Claim: 21. The long rod polishing device according to claim 15, wherein the battery is a lithium-ion battery. Claim: 22. The long rod polishing device according to claim 15, wherein the handle portion includes a grip portion that projects toward a side opposite to the pad and is configured to be gripped by a user. Claim: 23. The long rod polishing device according to claim 22, wherein the battery mounting portion is closer to the pad in a direction of the center axis of the rod portion than the grip portion is. Claim: 24. The long rod polishing device according to claim 15, wherein the handle portion includes a speed adjustment dial, and a switching state of the speed adjustment dial corresponds to a speed setting. Claim: 25. The long rod polishing device according to claim 24, wherein the handle portion includes a grip portion which projects toward a side opposite to the pad and is configured to be gripped by a user, and the speed adjustment dial is closer to the pad in a direction of the center axis of the rod portion than the grip portion is. Claim: 26. The long rod polishing device according to claim 15, wherein the electric motor includes a motor shaft rotatably driven by the electric power, a direction of the motor shaft intersects a direction of the center axis of the rod portion. Current International Class: 24; 24; 24; 24; 24; 24
