Abstract

PURPOSE:To reliably fix a bearing by accomodating a bearing having two parallel surfaces in a bearing accomodating hole through a guide groove formed on a housing, and positioning the bearing turned in a needed angle by a positioning plate. CONSTITUTION:A bearing 21 is fitted to a roller shaft 25. A bearing 21 fitted to the roller shaft 25 is fitted in a guide groove 29 with two parallel surfaces 22, 22 thereof matched with both walls of the guide groove 29. At that time, the bearing 21 is pushed in together with a positioning plate 33 and moved in a bearing storing hole 28. After that, the positioning plate 33 is turned clockwise in a 90-degree arc, and with the movement, the bearing 21 is turned to block up the lower end opening of the guide groove 29. Subsequently, a screw 37 is engaged with a screw hole 31 of a housing 27 through a hole 36 of the positioning plate 33 to fasten the positioning plate 33 to the housing 27.
