PURPOSE: To obtain the subject producing apparatus capable of pulling a container-fixing pin with both hands and laying a reactor with the same hands and returning the reactor to original position by only pushing the reactor back.

CONSTITUTION: This apparatus for producing soap is equipped with a pin- attaching plate 26 respectively fixed to both sides of a reactor 3, a container- fixed pin 9 inserted into the hole of the pin-attaching plate 26 and a container- fixing plate 8 having a notch 25 for receiving the container-fixing pin 9. A spring 27 fitted into the top of the container-fixing pin is suppressed by a washer 28 and a pin 29. The container-fixing pin has an engaging part 37 thicker than the top and the notch of the container-fixing plate consists of a slot part passing only top of the container-fixing pin and a holding part having size in which an engaging part is put. The end part of the container-fixing plate is inclined to the reactor side and the end 38 of the container-fixing plate exists at the position closer to the reactor side than the end of the engaging part.
