In a sensory test we examined variations of sleeve cap points fit for the form of drooping arms from the point of adaptability of motions. The results were as in the following : 1) In the slant form between the rear slant 2° and the front slant 4° it is better to displace the sleeve cap points forwards. The maximum of variations was about 1.7 cm. 2) In the front slant angles of drooping arms 5°～ 6° variation of sleeve cap points was about 0 cm. 3) In the slant form of more than 7° forwards it is better to displace the sleeve cap points rearwards. The variations were almost in proportion to the slant angles of drooping arms, and the maximum was about 2 cm
