<p>A torque wrench comprises a body member (2) containing a piston-cylinder assembly (10) to the piston of which is secured a shuttle member (14) reciprocable with the piston within the body member (2), and a housing (22) mounted on the body member (2) and including a drive member (28) pivotal about an axis (P) and having a neck portion (34) radially remote from the pivot axis (P). The shuttle member (14) has a cylindrical bore (16) therein the central longitudinal axis of which extends parallel with the pivot axis of the drive member (28), said bore (16) housing a cylindrical drive pin (18) in which is formed a transverse bore (20), the neck portion (34) of the drive member (28) being received within said bore (20) whereby, on linear movement of the piston, the drive member (28) is pivoted about the pivot axis (P) with the neck portion (34) of the drive member (28) undergoing guided sliding movement in the bore (20) of the drive pin (18), and the drive pin (18) pivoting about the central longitudinal axis of the bore (16) in the shuttle member (14). <IMAGE></p> |
