記載のリミツトスイツチ構造。[Scope of Claim for Utility Model Registration] (1) A limit switch that rotates a rotating shaft by tilting a roller lever due to a load on the roller, operates a plunger mechanism by the plunger pushing part of this, and operates a built-in switch by this plunger mechanism. In this invention, the roller lever mechanism is constructed by having a pair of lever parts facing each other and having their bases fixed to a rotating shaft and their tips fixed to a roller shaft supporting a roller, thereby imparting rigidity to the pair of lever parts. A limit switch structure characterized by forming a part. (2) The rigidity imparting part is formed by forming side pieces on both side edges of the lever part that are perpendicular to the surface of the lever part,
Rectangular convex portions and concave portions are formed alternately on these side pieces, and the convex portion of one lever portion is engaged with the concave portion of the other lever portion, and the convex portion of the other lever portion is engaged with the concave portion. 2. The limit switch structure according to claim 1, wherein the limit switch structure has a closed cross-sectional shape. (3) Claim (1) characterized in that the rigidity imparting portion is formed by forming grooves having an arcuate cross section on the face portion of the lever portion from the shaft attachment portion of the base portion to the tip side.
The limit switch structure described.
