Claims

[Scope of utility model registration request]

At the folding part of the folding table board in which the auxiliary table board is swingably hinged to the main table board, a sheath tube is fixed perpendicularly to the folding line along the underside of the main table board, and pushed deep inside the sheath tube. A spring is built in, and a bar rod is inserted into the front part so as to be able to slide in and out by being compressed by the push spring, and the push spring and the lock bar are inserted in a cylindrical body that is connected orthogonally to one side of the outer end of the sheath tube. and is biased by a push spring so that the tip of the lock rod is brought into pressure contact with the side surface of the bolt and engaged with the front end of the bolt,
An operating protrusion is provided that protrudes outward from the middle part of the lock lever through the guide hole of the cylinder, and when the auxiliary table board is moved downwardly, it slides into contact with the operating protrusion and resists the biasing force of the pressing spring. An operating device for a folding table board, characterized in that an operation plate provided with a convex portion for pressing in the opposite direction is attached to a portion of the lower surface of the auxiliary table board close to the folding line.
