PROBLEM TO BE SOLVED: To provide an auxiliary lock for an aluminum sash capable of solving such a problem that a magnetic force is weakened due to a long time use, conventionally, there is the auxiliary lock for the aluminum sash fixing by rotating a knob inserted in a window frame such as the aluminum sash or the like or projecting a stopper by the knob, however, the sash can't be opened and closed in a state to mount it on the window frame, and it can be used in a state to mount it by using magnetic force. SOLUTION: A spring material is used for raising and falling an undulating plate for the subsidiary lock for the aluminum sash storing the undulating plate by freely coming in and out of a box-shaped substrate with a pivot.
