PROBLEM TO BE SOLVED: To provide a looseness prevention structure for a push button employed in equipment having a push button, solving a problem caused by deviation of a push switch with reference to a base plate of the push switch. SOLUTION: The looseness prevention structure is provided on the equipment 1 comprising a base 7, the push switch 4 having a shaft 5 axially slidable, mounted on the base plate 3 fixed to the base, and the push button 6 fitted into the shaft of the push switch. Pressing the push button in the axial direction of the shaft causes the shaft to slide to allow the push switch to generate a signal. The chattering prevention structure is to prevent the push button 6 from chattering in the radial direction of the shaft 5, while the push button 6 is pressed. A guide part 9 for restricting the push button 6 in the radial direction of the shaft and guiding in the pressing direction is movably supported in the radial direction of the shaft 5 with reference to the base 7.
