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
There are provided weight shaft 10 to be connected with arm 1a of dynamometer 1, weight placement section 11 supported by weight shaft 10 and weights 21 to be stacked on weight placement section 11. Weight shaft 10 includes constricted segment K at a predetermined position in the axial direction. Each weight 21 includes a cutout portion 24 cut out from a middle of a side end portion 22a and arranged to receive the constricted segment K. The cutout width of this cutout portion 24 is greater at a round hole 25 than at an open end 26b. Weights 21 are stacked on weight placement section 11 by lowering each weight in the state in which the constricted segment is inserted from the open end 26b into the round hole 25. 展开▼
