Abstract:
There are provided weight shaft  10  to be connected with arm  1 a  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  22 a  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  26 b.  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  26 b  into the round hole  25.

Claim (Index 11):
A calibration apparatus for a dynamometer, the calibration apparatus comprising:\n a weight shaft to be connected with an arm of the dynamometer; a weight placement section supported by the weight shaft; and weights to be stacked on the weight placement section; the calibration apparatus being arranged to perform torque calibration by comparison between a load of the weights and an indicated load of a load measuring device; the weight shaft including a constricted segment at a predetermined position in an axial direction of the weight shaft; each weight includes a cutout portion which is cut out from a middle of an end portion of the weight to a central region of the weight and adapted to be introduced onto the constricted segment so that the constricted segment is inserted in the cutout portion of the weight; the cutout portion being so formed that a cutout width of the cutout portion in the central region of the weight is greater than or equal to an outside diameter of a remaining segment of the weight shaft other than the constricted segment; the cutout portion including a guide slit guiding from an open end at the middle of the end portion to a bottom portion of the cutout portion in the central region; the guide slit including an upper slit on an upper surface's side and a lower slit on a lower surface's side; and the cutout width of one of the upper and lower slits being greater than or equal to the outside diameter of the constricted segment, and smaller than or equal to the outside diameter of the remaining segment.
