Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent the generation of local stress in a cage of a ball bearing provided between a flexible spline and an elliptical cam of a wave motion gear reducer.SOLUTION: A cage 10 has a structure of five pieces separated in a circumferential direction. Respective circumferential angles θ-θcorresponding to lengths of the separated pieces 21-25 in the circumferential direction are less than 90°.SELECTED DRAWING: Figure 1 【課題】波動歯車減速機のフレクスプラインと楕円状カムとの間に介在する玉軸受の保持器において、局部的な応力の発生を防止する。【解決手段】保持器１０は、周方向に五分割された構造にする。各分割片２１〜２５の周方向長さに対応の円周角θ１〜θ５は、それぞれ９０°未満とする。【選択図】図１
