<p>PURPOSE:To sufficiently exhibit the effect of a weight embedded in a head for minimizing the movement of the head when a ball is driven in a so-called metal wood. CONSTITUTION:A head 1 has an outer shell part 2 consisting of titanium alloy and having a hollow part 2 in the inside. The volume of the hollow part 2 is 240cm<3> or more. A weight 18 consisting of titanium alloy is embedded on the lower part rear side in the outer shell part 3. The weight of the weight 18 is 10g or more. The volume of the hollow part 2 is set large as 240cm<3> or more, whereby the head 1 is difficult to move. The weight 18 is set heavy as 10g or more, whereby the effect of the weight 1 can be sufficiently exhibited.</p> |
