PROBLEM TO BE SOLVED: To provide a noise measurement device capable of facilitating a coupling work for a plurality of amplifiers for measurement, a vibration measurement device, and an amplifier for measurement of vibration. SOLUTION: This noise measurement device, vibration measurement device or amplifier 1 for measurement of vibration has a roughly rectangular parallelepiped shaped chassis. The device is equipped with a connection fitting 8 for connecting the chassis 2 to another chassis 2 which is in contact with the former chassis 2 at the left side and/or right side thereof. The connection fitting 8 is constituted of a base 15 and a hook plate 16. The connection fitting 8 is fixed to the top face 7 of the chassis 2 with a single screw 17. The connection fitting 8 is fixed by changing its orientation by a right angle depending on the case where the plurality of chassis 2 are used by connecting them to each other or the case where the chassis 2 is used in a stand alone fashion.
