    • A multijoint manipulator apparatus includes a tubular-member, linear-motion-transmission-members, a drive-unit, a position-detector, a tension-detector, an operation-unit, and a movement-degree-calculation-unit. The linear-members are inserted in the tubular-member, one end and the other end of each of the linear-members being fixed to the vicinity of a joint of the tubular-member and the drive-unit, respectively. The drive-unit moves the linear-members. The position-detector and the tension-detector detect positions and tension of the linear-members, respectively. A desired position/posture of a point of interest is input to the operation-unit. The calculation-unit calculates a current position/posture of the point, a weighting factor serving to give priority to and move the linear-members the tension of which is relatively low among the linear-members, and movement degrees of the linear-members to move the point to the desired position/posture, and causes the drive-unit to pull the linear-members.

    • A method of manufacturing a retainer for a roller bearing made of a metal plate and has a tubular main portion, pockets formed in the main portion intermittently concerning a circumferential direction and capable of retaining rollers rollably, and an outwardly oriented flange-like collar portion. An annular intermediate material is formed by die cutting the metal plate, and after a second intermediate material is formed by forming through holes in the intermediate material intermittently, a portion of the second intermediate material excluding a radially outer end portion is plastically deformed into a tubular shape. The portion plastically deformed tubular shape is formed as the main portion, a portion corresponding to the radially outer end portion of the second intermediate material is formed as the collar portion or a collar portion element for forming the collar portion, and portions corresponding to the through holes are formed as the pockets.
