  • Grip member for wrench
    Publication number: 20050217438
    Abstract: A wrench includes a body and a grip member. The body includes a head on an end thereof and a handle on another end thereof. The handle includes two opposed sidewalls and a recessed portion between the sidewalls. The handle further includes a grasping section, with the recessed portion being at least partially located in the grasping section. The grip member is securely attached to the recessed portion of the handle. Thus, the driving force from the user can be effectively transmitted to the head of the body, as the sidewalls of the handle withstand most part of the driving force. Preferably, each sidewall of the handle extends across a central line of a height of the combined handle/grip member.
