ABSTRACT:
In a seal device in a displacement measuring instrument, comprising a hollow case fixed to one member, a connecting rod for imparting a displacement of the other member to a displacement detecting mechanism housed in the hollow case through the opening and seal members disposed at opposite sides of the opening, for shielding a penetrating portion of said connecting rod, to enhance the drip-proof performance, a difference is given between the positions of the forward ends of lip members constituting said seal members, whereby the forward end of the lip member disposed at one side where liquid drops are generated is projected farther than the forward end of the lip member disposed at the other side, and/or a liquid receiving groove extending along the opening is provided at least at one side of the inner surface of the hollow case, liquid drain holes are formed in the bottoms of the liquid receiving grooves, filters for excluding dust intruding from outside are provided in the liquid drain holes, and/or liquid breaking means for precluding a liquid flow intruding from outside of the hollow case are provided on the outer peripheral surface of the connecting rod.
