摘要： PROBLEM TO BE SOLVED: To provide a small and compact valve lifter small in number of component parts. SOLUTION: This valve lifter forms a screw hole 13 on a closure end plate 9 of a guide cap 7 built in between a cam 5 and a top end part of a valve stem 3a, and an adjust bolt 14 is screwed and engaged with the screw hole 13. The adjust bolt 14 is pressed to the valve system 3a by a spring. The screw threads of the screw hole 13 and the adjust bolt 14 are formed to be saw-tooth, and the adjust bolt 14 is constituted to move to the valve steam 3a side by elastic force of the spring. The length of the valve lifter in the axial direction can be compacted by the screw engagement of the screw hole 13 formed on the guide cap 7 with the adjust bolt 14.

摘要： PROBLEM TO BE SOLVED: To contact a planetary roller and a carrier with each other in an optimal condition, and improve a lubricating condition of a contact part of the planetary roller and an input shaft by contacting/guiding the carrier with/to an outer peripheral surface of the input shaft. SOLUTION: An oil containing member 5 is arranged between an inner circumferential surface of a carrier 3 and an input shaft 1, and the carrier 3 is contacted with and guided to the input shaft 1 through the oil containing member 5. For example, the oil containing member 5 is formed by impregnating lubricating oil into a porous material formed of a sintered material, or by compressing a mixture of resin and lubricating oil by heating and cooling, and an inner peripheral surface of the carrier 3 is installed so as to contact with the input shaft 1 or the input shaft 1 and a planetary roller 2. Therefore, looseness of the carrier 3 is eliminated, and the axis of the carrier 3 always coincides with the axis of the input shaft 1, and operation can be performed in a condition where a contact surface pressure value is lowest between the planetary roller 2 and the carrier 3. Lubricating oil of the oil containing member 5 is supplied to an outer peripheral surface of the input shaft 1, and a lubricating condition of a contact part of the planetary roller 2 and the input shaft 1 is improved.

摘要： PROBLEM TO BE SOLVED: To dispense with side plates to be attached to both sides of a fixed wheel by extending both ends of the fixed wheel in the axial direction, and an inner flange for guiding a planetary roller to the revolutional direction at the inner dia. part of both ends extended. SOLUTION: Both ends of a fixed wheel 4 are respectively extended in the axial direction in correspondence with almost the thickness of side plate, and at the inner dia. part of the extended ends annular inner flanges 4a are respectively formed. This flange 4a guides a planetary roller 2 to the revolutional direction through a slightly small gap in the axial direction. Accordingly, side plates are unnecessary on both sides of the fixed wheel 4. With the formation of the flange 4a at right angles to the axis of the wheel 4, the perpendicularity to the roller 2 can be ensured easily, thereby preventing generation of skew in the roller 2.

摘要： PURPOSE:To increase durability of a vibration-proof material by providing an interference portion, projected in the direction to narrow a clearance formed between inner and outer external cylinders, on either of the two cylinders, in an external cylinder for tri-board type constant-speed joint composed of the inner and outer external cylinders and provided with the vibration-proof material in a clearance formed between them. CONSTITUTION:An external cylinder is composed of a bottomed cup type inner external cylinder 1 and a bottomed cup type outer external cylinder 2. A vibration-proof material 4 of elastic material such as rubber, etc., is provided between a circumferential clearance 3 formed between both cylinders by combining both of them. A split ring 13 is formed by a square-section metal wire of resiliency, formed in clover-shape so that it can be fitted onto the external surface of the inner external cylinder 1, and cut off in some places 14. If excessive torque is given and both the inner and outer external cylinders 1 and 2 are relatively displaced in rotating direction, the split ring 13 will be interfered with the internal peripheral surface of the outer external cylinder 2 to restrict more displacement. Thus excessive deformation of the vibration-proof material 4 can be prevented.
