Beschreibung
Zusammenfassung:	The invention achieves a structure capable of suppressing, in a worm reducer provided with a means for elastically biasing the tip section of a worm toward a worm wheel side, the tip section of the worm from being displaced in a direction perpendicular to the biasing direction. In the present invention, a support bearing (17) that supports the tip section of a worm (16) is elastically biased by an elastic biasing means (81) toward a worm wheel (15) side, and is elastically clamped by an elastic clamping means (82) from both directions of a first direction parallel to the biasing direction of the elastic biasing means (81) and a second direction perpendicular to the central axis of a worm accommodation part (22). 本发明实现一种构造，在具备朝向蜗轮侧弹性地对蜗杆的前端部进行施力的机构的蜗轮减速器中，能够抑制蜗杆的前端部在与施力方向成直角的方向上位移。支撑蜗杆(16)的前端部的支撑轴承(17)由弹性施力机构(81)朝向蜗轮(15)侧弹性地施力，而且由弹性夹持机构(82)在与平行于弹性施力机构(81)的施力方向的第一方向和蜗杆收纳部(22)的中心轴正交的第二方向上从两侧弹性地夹持。
