A detection part provided on a member that performs periodic motion with respect to the compressor body, and a detector facing the detection part and fixed to the compressor body. In the compressor rotation speed detection device, which detects the rotation speed of the compressor as a change in magnetic flux, the detector is provided with a drive section made of a shape memory alloy that senses the ambient temperature and moves the detection element section, When the compressor is abnormally overheated, the detection element part 1
1. A rotational speed detection device for a compressor, comprising an abnormal overheat detection mechanism that detects abnormal overheating of the compressor by moving a distance relative to the compressor. 2. The rotational speed detection device for a compressor according to claim 1, wherein the detector is an electromagnetic pickup, and the detection element portion is a central axis of the electromagnetic pickup. 3. The rotational speed detecting device for a compressor as set forth in claim 2, wherein the driving portion is the central shaft itself. 4. The rotational speed detection device for a compaction machine according to claim 2, wherein the drive section is a spring that biases the central shaft.
