Abstract
A shock-absorbing mechanism for use in a dial gage where longitudinal motion of the spindle is converted to rotational motion of a pointer shaft gear by a pinion shaft rotated by said spindle and a magnifying gear coaxially and idlingly meshed with said pinion shaft, comprising a star-shaped pressure spring with radiately extending, elastic branches having not only elasticity in the axial direction of said pinion shaft but also high rigidity in the rotating direction thereof, and a dished spring bearing to deform said pressure spring so as to provide said axial elasticity, said star-shaped pressure spring and dished spring bearing being disposed coaxially with said magnifying gear and a stopper ring fixed on said pinion shaft so that the magnifying gear is pressed against the stopper ring in a frictionally contacted manner.
