<p>A device for insertion into the handgrip portion (16) of a game or sport article, comprises an elongated casing adapted to be inserted into an axial hole (15) of the handgrip portion, a mass (2) movable axially relative to the casing, and means arranged to vary the position of the mass in order to place it in a pre-established position with respect to the casing, comprising a screw (3) and nut (4). One member of this pair is rigidly connected to the mass and the other member is actuable from the outside of the casing, in order to vary the position of the mass relative to the casing so as to displace the position of the centre-of-mass of the article in an axial direction. <IMAGE></p> |
