Claims

[Claims for Utility Model Registration] (1) A cylindrical lifter body having a female thread formed on its inner peripheral surface, a plunger disposed within the cylindrical lifter body and having a male thread screwed into the female thread; A mechanical spring consisting of a torsion spring disposed between the cylindrical lift body and the plunger, one end of which is latched to the cylindrical lift body and the other end of which is latched to the plunger to apply a torsional force to extend the plunger. The thrust adjuster is characterized in that the plunger has a two-piece structure including a tip plunger member and a male threaded member, and a spacer spring is disposed between the two members to form a constant axial gap between the two members. Mechanical lash adjuster. (2) The mechanical lash adjuster according to claim 1, wherein the threads formed in the cylindrical lifter body and the male threaded member are symmetrical trapezoidal threads. (3) The mechanical lash adjuster according to claim 1, wherein the axial gap between the tip plunger member and the male screw member is adjustable by a shim.
