Abstract

A golf club head includes a body and a retaining element removably mounted to the body. The retaining element includes a main body and an annular wall extending from a side of the main body of the retaining element. The annular wall defines a compartment for receiving a weight that is retained to the body of the golf club head by the retaining element. A vibration absorbing washer is received in the compartment of the retaining element and mounted to the weight. The vibration absorbing washer absorbs vibration during swing, thereby enhancing assembling reliability of the weight.

Claims

1. A golf club head comprising:

a body having a recess, with a bottom wall defining the recess including a positioning hole, and with a peripheral wall defining the recess including an inner thread;

a retaining element removably mounted to the body, with the retaining element including a main body and an annular wall extending from a side of the main body of the retaining element, with the annular wall defining a compartment, and with the annular wall of the retaining element including an outer thread for threadedly engaging with the inner thread of the body;

a weight received in the compartment of the retaining element and retained to the body of the golf club head by the retaining element, with the weight including a flange on an outer periphery thereof, with the flange of the weight having a diameter greater than that of the positioning hole of the bottom wall, with an end of the weight extending through the positioning hole, and with the flange of the weight abutting against the bottom wall defining the recess; and

at least one vibration absorbing washer received in the compartment of the retaining element and mounted to a side of the weight, with the vibration absorbing washer absorbing vibration during swing, thereby enhancing assembling reliability of the weight.

2. The golf club head as claimed in claim 1, with the body of the golf club head including a sole having the recess, and with the retaining element being received in the recess.
