    Abstract: When a reaction solution in a reaction vessel is irradiated with light to measure an amount of transmitted light or the like, the reaction vessel rattles due to vibration and an optical axis is shifted, resulting in a decrease in measurement accuracy.
    A torsion coil spring 302 for urging the reaction vessel is provided in a heat block 200 having a plurality of reaction vessel placement holes 201 on which the reaction vessel 112 is mounted, the reaction vessel 112 includes a protrusion 501 on a part of a side surface, and when the reaction vessel is inserted in the hole, an arm of the torsion coil spring 302 is operated so as to be retreated along the protrusion, and, when the reaction vessel is fitted in the hole, it urges the protrusion horizontally with a lower side in a vertical direction and urges the reaction vessel 112 to press against the wall of the hole 201.
