>>32376552ねじ (Neji) means screw/spring and apparently ねじ巻き (Nejimaki) is what you call that key-like thing (I don't know what these are called in English) on it's back that one uses to wind-up it up. So if you combined ねじ + ま + きつね you get Nejimakitsune, which contains the phrase Nejimaki. So basically, it's just called wind-up fox with a slightly puny name. I'm assuming the (仮) thing might be a reference to the microwave in Steins;Gate.
