    Abstract: A rocker arm formed of material in a shape of sheet has a pair of side wall portions, a connection portion for a valve stem receiving portion and a connection portion for a pivot receiving portion which interconnect the side wall portions, and an open portion for arranging a roller which is formed between the two connection portions. A distance between outer side surfaces of the pair of side wall portions in the connection portion for the valve stem receiving portion is reduced in a direction from upper edges to lower edges in a step-like shape having two or more step differences, whereby a first outer side surface and a second outer side surface are formed.

    Abstract: A step portion is formed at an outer peripheral surface of an axially-central portion of an outer ring, and is smaller in diameter than outer peripheral surfaces of axial opposite end portions of the outer ring. The step portion is continuously formed over an entire periphery of the outer ring, and has a predetermined width over the entire periphery. The outer peripheral surface and inner peripheral surface of the outer ring are pressed radially inwardly, and therefore are bulged radially inwardly into a step-like shape to form the step portion having an axis coinciding with a axis of the outer ring. A pedestal of a cylinder block and a cap member retain the outer peripheral surface of the step portion, thereby positioning the outer ring in the axial direction and also preventing a movement of the outer ring in the axial direction.

    Abstract translation: 在外圈的轴向中央部的外周面形成台阶部，其直径比外圈的轴向相对端部的外周面小。 台阶部分在外圈的整个周边上连续地形成，并且在整个周边上具有预定的宽度。 外圈的外周面和内周面被径向向内挤压，因此被径向向内凸出成阶梯状，以形成具有与外圈的轴线重合的轴的台阶部。 气缸体和盖构件的基座保持台阶部的外周面，从而将外圈沿轴向定位，并且还防止外圈沿轴向移动。

    Abstract: The bearing device 4 is press-fitted between the inside surface of the axis insertion hole of a steering column and the outside surface of a steering axis inserted into the axis insertion hole so as to support the steering axis. The bearing device 4 comprises a roller bearing arranged on the outside surface of the steering axis and a spacer ring arranged between the outside surface of the roller bearing and the inside surface of the axis insertion hole. The spacer ring comprises a wall thickness holding unit for holding the thickness of its wall in the radius direction and a thickness reduction unit which is provided on at least one site of the inside and outside surfaces and its end in the vicinity of the wall thickness holding unit and which reduces the thickness of the wall to facilitate deformation of the spacer ring.
