Abstract

PURPOSE: To eliminate a precise machining work process and reduce a manufacturing cost by a method wherein supporting protuberances are formed on a circular inner peripheral surface for mounting a bearing in the gear box made of die cast light metal and the bearing is force fitted and secured therewithin, in a speed change gear device for an automatic doop equipment or the like.
CONSTITUTION: The mounting part 6 having the circular inner peripherial surface 4 is formed on the internal surface of the side wall 2 of the gear box formed by die cast molding method from a light metal material. A plurality of supporting protuberances 20 are formed on the circular inner peripheral surface 4 with intervals in the peripheral direction. The inner diameter D1 of the circular inner peripheral surface 4 is somewhat larger than the circular outer peripheral surface 12 of the bearing member 14 to be mounted therewithin and a diameter D3 of a circle defined by the supporting protuberances 20 is somewhat smaller than the outer diameter D2 of the circular outer pherpheral surface of the bearing member 14. The bearing member 14 is secured within the mounting part 6 thus formed by force insert-fitting.
