Claims

[Scope of utility model registration request]

It is formed in a columnar shape, has a collision part whose lower end is spherically processed, and a rod-shaped holding part at the upper end of the collision part, and is held on a support plate supported at a predetermined height by an angle. In a dynamic dent strength testing device that tests dent resistance by dropping a weight on a thin steel plate placed at the bottom end of an angle,
a collet formed in a hollow shape and having fingers made of a plurality of elastic members at its tip; a connecting shaft that is vertically movable and connected to a ring fitted on the outside of the fingers and penetrated within the collet; , a gripping device comprising an elastic member that constantly urges the finger inward through the connection shaft is provided on the support plate, and the gripping device is gripped by the finger by sliding the connection shaft downward. A dynamic dent strength testing device characterized in that the holding portion of the weight is opened at a plurality of locations at the same time.
