A dial knob for a microwave oven is provided to improve the durability of products by minimizing damage to a knob body made of metal materials during a process of manufacturing the dial knob. A dial knob for a microwave oven includes a knob body(51), a push button(55), a fixing device, and an interlocking device. The knob body(51) is a hollow cylinder having one open surface and forms an external appearance. The push button(55) is coupled with the inside of the knob body(51) and is installed in an encoder. The fixing device is installed at the side where the knob body(51) and the push button(55) correspond and prevents the knob body(51) and the push button(55) from being randomly separated. The interlocking device is installed at the side where the knob body(51) and the push button(55) correspond, and makes the knob body(51) and the push button(55) interlocked as single body.
