摘要： PURPOSE:To provide a rotary valve sleeve, which can be manufactured without generating distortion, and a device for manufacturing it. CONSTITUTION:A rotary valve sleeve 10 has wide grooves 11 having a wide opening width and narrow grooves 12 having a narrow opening width formed between lands projected from the inner peripheral part, and houses a spool valve member in the inner peripheral side thereof freely to be rotated. The narrow grooves 12 are formed deeper than the wide grooves 1 to take a balance of the volume in a constant range around the wide groove 11 and the volume in a constant range around the narrow groove 12. Consequently, unevenness of deformation quantity due to quenching is eliminated to previously prevent the generation of distortion.

摘要： PURPOSE:To simplify a supporting device and to attain miniaturization by providing, at a position opposite to the diameter direction of the inner/outer cylinder of one presser, the other presser that is fixed on a movable frame. CONSTITUTION:A piston 10 is extended and inserted into an opening 8a by a cylinder 12. When a vertically movable frame 26 is lowered by a motor 20, the upper end of a tube 22 is held and fixed by a tube holder 32. Then, a piston 58 is extended by a pressurizing cylinder, one holder 60 is moved left and abutted on the tube 22 from the right side. Also, when the piston 58 is extended, a movable frame 39 is moved right. A holder 68 is abutted on the tube 22 from the left side. In addition, when the piston 58 is extended, a mutually approaching force is actuated between the holder 60 and 68, and the outer wall of the tube 22 is calked by a calking punch and bitten in a calking groove. Since calking is completed when the piston 58 is moved forward for a prescribed stroke, the movable frame 39 is then moved left by means of a spring when the piston 58 is contracted.

摘要： PURPOSE:To provide a press fitting device which can surely press fit a first member such as a housing H and a second member such as a spacer S into a cylindrical member such as a rack tube T. CONSTITUTION:A housing H is held almost perpendicular by a housing supporting unit, and an end face on the press fit side of the housing H is held by a spacer guide 112 from the outer circumference with a space left above. A spacer S is conveyed by a spacer conveying unit to be mounted in a space surrounded by the spacer guide 112 on the upper end face of the housing H, and a press fitting means 38 is operated to lower a rack tube T. At this time, first, the rack tube T is brought into contact with the upper end of the second member guiding means 112 while being engaged with the spacer S, but since the spacer guide 112 is supported by slide supporting means 124 to 137 slidable in the axial direction, it is also lowered while being pressed by the rack tube T. A cylindrical member holding means is further lowered, and the housing H is press fit into the rack tube T.

SOLUTION: This solenoid-driven valve 10 has an intake valve 14 arranged in an internal combustion engine, a rocking member 20, an intermediate member 61, an upper ball 71 and a lower ball 76. The rocking member 20 makes rocking motion by operating electromagnetic force. The intermediate member 61 connects a part between the intake valve 14 and the rocking member 20, and transmits the rocking motion of the rocking member 20 to the intake valve 14 as linear motion. The upper ball 71 has a curved surface 71a and is arranged between the rocking member 20 and the intermediate member 61. The lower ball 76 has a curved surface 76a, and is arranged between the intake valve 14 and the intermediate member 61. The upper ball 71 rotates to the rocking member 20 while slidingly contacting the curved surface 71a with the rocking member 20, and the lower ball 76 rotates to the intake valve 14 while slidingly contacting the curved surface 76a with the intake valve 14.
