DYNAMOMETER-USE CALIBRATION DEVICE, WEIGHT FOR DYNAMOMETER-USE CALIBRATION DEVICE, WEIGHT SHAFT FOR DYNAMOMETER-USE CALIBRATION DEVICE, AND STOWAGE BOX FOR WEIGHT FOR DYNAMOMETER-USE CALIBRATION DEVICE
DYNAMOMETER-USE CALIBRATION DEVICE, WEIGHT FOR DYNAMOMETER-USE CALIBRATION DEVICE, WEIGHT SHAFT FOR DYNAMOMETER-USE CALIBRATION DEVICE, AND STOWAGE BOX FOR WEIGHT FOR DYNAMOMETER-USE CALIBRATION DEVICE
The present invention is provided with: a weight shaft 10 provided to an arm 1a of a dynamometer 1; a weight placement section 11 supported by the weight shaft 10; and weights 21 that are loaded onto the weight placement section 11. The weight shaft 10 is provided with constricted sections K at any position in the axial direction; meanwhile, the weights 21 are each provided with a cutout section 24 that is cut out from the middle of a side end section 22a and is introduced onto the constricted section K. The cutout width of the cutout section 24 is formed so that a round hole 25 is wider than an opening section 26b. The weights 21 are descended while in a state of having been inserted into the constricted section K from the opening section 26b to the round hole 25, and sequentially loaded onto the weight placement section 11.
