Abstract (en)
The present invention has an object of providing a seaming device that does not need the supply of a lubricant at a high pressure from an outside, obtains a sufficient flow rate while suppressing the leakage of the lubricant, and obtains sufficient lubricating performance and heat exhausting performance even when the seaming device is used at a low speed or at a high load. Seaming rolls (451) and (452) have, therein, a lubricant pump mechanism that transfers a lubricating oil between a lubricant path (454) of a seaming roll pin (453) and a bearing (458).
