Claims

[Scope of utility model registration request]

a support stand that is capable of moving a tightening device for tightening end bolts to the cylinder head of the engine between a position above an end bolt carrying stand for supplying and setting the end bolts and above a setting position of the cylinder head;
The rotary drive unit is composed of a nut runner type rotary drive unit with a built-in drive source that can adjust the rotational speed of the rotary shaft, and an elevating device that moves the rotary drive unit up and down with respect to the support base, and further includes: At the lower end of the rotating shaft, there is a cylinder whose lower end is open and a slit in the axial direction is provided in the side wall. At the same time, there is provided a chuck portion consisting of a pair of opposing clamping levers, each of which is rotatably biased via a spring provided at each upper end so that a protrusion provided at the lower end thereof approaches each other at all times; An automatic tightening device for end bolts in a cylinder head of an engine, characterized in that an end bolt carrying table is provided with a clamping device for elastically clamping a flange portion at the lower end of the head of the end bolt.
