Abstract: An outer joint member for a constant velocity universal joint is formed by a face spline forming apparatus and a face spline forming method. The face spline forming apparatus includes a punch member having a tooth portion for forming a face spline, a pedestal having an end-surface receiving surface for receiving an opening end surface of a cup section, and a shaft member having an inner-surface receiving surface for receiving a bottom-wall inner surface of the cup section. The opening end surface and the bottom-wall inner surface are brought into a simultaneous pressure receiving state. In this state, the punch member performs a rocking motion to form the face spline in a bottom-wall back surface due to plastic deformation caused by the tooth portion of the punch member.

Abstract: A housing slidably guides a slider, which is driven in response to selection of a shift range of an automatic transmission. Upper and lateral sides of a movable range of the slider are covered with the housing. Thereby, application of hydraulic fluid and foreign objects to guide rails is limited to limit malfunction of the slider. Furthermore, even when the hydraulic fluid and foreign objects adhere to the guide rails, the hydraulic fluid and foreign objects can be collected at ends of the movable range of the slider and can be expelled to an outside of the housing through open ends of the housing.

Abstract: A rotor shaft is supported in a rotatable manner at both ends by bearings respectively disposed to a housing forming a part of a stator and provided with a positioning portion of the bearing in at least one shaft end. The positioning portion is formed of an annular step-like rise portion that abuts on a circular arc surface provided to an inner ring corner of the bearing. A rotor shaft capable of holding the bearing in a stable manner over a long period is thus obtained without increasing the number of components and the numbers of working processes and assembly man-hours for the shaft. It thus becomes possible to solve problems, such as an increase in cost due to a large amount of working margin and increases of the direct material cost and in weight due to a larger finishing diameter of the shaft.
