Abstract

PURPOSE:To rationalize assembly of a measuring instrument, and also to realize a long life of a commodity, by combining a magnet instead of a spring, and installing it to a measuring needle, etc. CONSTITUTION:For instance, a coma 3 is formed by a resin magnet and a needle is attached. Subsequently, a cylindrical coma 4 is made on the outside, and magnetic force is provided so as to conform with a desired rotation. After that, the coma 3 is covered with the coma 4. In this case, magnetic force is applied so that the upper part of the coma 3 and the upper part of the coma 4 become the same pole, and the lower part of the coma 3 and the lower part of the coma 4 become the same pole, as well. As a result, the coma 3 and 4 repel each other, and the coma 3 comes to float in the coma 4. The comas 3, 4 held by each other in this way are covered with a coma 5, by which one device is obtained. The coma 4 and the coma 3 are provided with a hole bigger than the man shaft, and a hole closely fitted to the main shaft, respectively, therefore, the needle is operated by a rotation of the main shaft. In this way, assembly of a measuring instrument is rationalized, and also a long life of the measuring instrument is realized.
