PROBLEM TO BE SOLVED: To provide a sensor unit which absorbs impact and vibration by means of not only a volume and a material of impact/vibration absorption material but also a structure for absorbing impact and vibration and which is easy to be attached to/detached from a measurement object, and provide a motion measuring system using the sensor unit.SOLUTION: Each of sensor units 10A-10C to be attached to a measurement object 1 includes a first buffer part 30 having an outer wall 32 contacting with an attachment face 1B of the measurement object, a second buffer part 40 disposed inside the outer wall of the first buffer part and being softer than the first buffer part, a sensor part 20 held within the second buffer part, and a thin fixation member 33 which extends from an end face of the outer wall of the first buffer part, is mounted to cover an end circumferential face of the measurement object, and fixes the first buffer part to the attachment face of the measurement object. |
