AI Technical Summary

Technical Problem

In the prior art, when a grease storage section is provided on the sliding surface of a component, the volume needs to be increased to avoid lubricant depletion, which leads to a reduction in the sliding surface area, an increase in surface pressure, increased wear, and a decrease in strength.

Method used

A lubricant flow path with an opening is provided on the first component, through which lubricant is supplied to the sliding surface, avoiding enlarging the opening of the sliding surface and maintaining the necessary amount of lubricant.

Benefits of technology

It inhibits the reduction of the sliding surface area, prevents lubricant depletion, reduces wear, and maintains strength.

Abstract

Provided is a device capable of supplying a lubricant to a surface at which two members meet. A device (1) such as a stapler is provided with a first member (2) having a first surface (20) and a second member (3) having a second surface (30) that meets the first surface (20) in part or entirely, the first member (2) and the second member (3) being configured to act in opposition to each other, the first member (2) having a flow path (5) of the lubricant provided with an opening (50) in the first surface (20) on a surface (23a) other than the first surface (20).
