A pair of moving members having a U-shaped cross section consisting of a bottom plate and left and right upright plates are provided on the guide member so as to be movable in different directions in the radial direction of the lid, and the pair of movements A pair of guide rolls are implanted at the inner end of each member, and the cover member A pair of slanted guide holes that are movable in a direction perpendicular to the direction of movement of the pair of moving members, and that form a mutual shape that can be slidably fitted to the pair of guide rolls. And a spring for locking the pair of moving members to move inwardly between the pair of guide rolls, and the movable plate via the rotating horizontal shaft by the swinging motion of the operating member. There is provided a pressure cooker characterized in that an operating arm for moving the moving member in a direction orthogonal to the moving direction of the moving member is provided, and the pair of locking members are fixed to the outer end portions of the pair of moving members. .

  According to a second aspect of the present invention, there is provided a safety member that is provided on the lid body and can be moved up and down by a change in internal pressure of the container body and the moving member. Provided with a safety mechanism composed of a locking portion capable of preventing lateral movement, and further provided with a steam vent valve having an adjustment weight for adjusting the pressure in the container body on the lid body. The invention according to claim 3 is characterized in that an opening / closing valve is provided in the safety member to open and escape steam when the pressure in the container body in the closed state increases excessively.

  As described above, according to the present invention, the moving plate is moved in a direction orthogonal to the moving direction of the moving member against the locking spring by moving the operating member upright and swinging. By moving and operating the above-mentioned operation member in a tilting and swinging manner, the moving plate is moved backward in the direction perpendicular to the moving direction by the locking spring. The pair of moving members are moved in different directions in the radial direction of the lid body by the fitting with the oblique guide holes and the guide member, and the lid body is fixed to the container body at the fixed position where the pair of locking members are located inside.

  According to a second aspect of the present invention, there is provided a safety member provided on the lid body and movable up and down by a change in internal pressure of the container body and the moving member. Since a safety mechanism comprising a locking portion that can prevent the outward movement of the safety member is provided, the safety member can be raised at a fixed position where the pair of locking members are located on the inner side. On the other hand, when the pressure in the container body drops, the safety member will drop. When the pressure in the container body is still high, the operation member is raised and fixed. When trying to move the moving member outward from the position to the release position, the outward movement of the moving member is prevented by the locking portion, so that unintentional removal of the lid can be prevented and safety can be improved. In addition, the lid body Since the steam release valve having an adjustment weight for adjusting the pressure in the body is provided, the pressure in the container body can be adjusted, safety can be improved, and the invention according to claim 3 is provided. In addition, since the safety member is provided with an on-off valve that opens and escapes steam when an excessive pressure rise in the container body in the closed state, an excessive pressure rise occurs in addition to the pressure adjusting action of the steam release valve. Sometimes the on-off valve opens to allow the steam to escape, thereby further enhancing safety.
