Connecting member for an abrasive member

Abstract

A connecting member for an abrasive member includes a body and a fixing member. The body includes a connecting portion, a cylindrical portion connected to an end of the connecting portion and having a compartment, and an opening intercommunicated with the compartment. The compartment includes an inner periphery having an inner threaded portion. The fixing member includes a stopper portion and an outer threaded portion integrally connected to the stopper portion and threadedly engaged with the inner threaded portion. The outer threaded portion of the fixing member extends through an axial hole of an abrasive member and is, then, threadedly engaged with the inner threaded portion of the body. A bottom face of the cylindrical portion and the top face of the stopper portion together clamp an upper face and a lower face of the abrasive member, thereby securely fixing the abrasive member and the body together.
