摘要： PROBLEM TO BE SOLVED: To provide a fluid pump suitable for a fuel high pressure injection pump of a diesel engine by preventing abnormal wear or seizure in a sliding part between the cam and the plunger. SOLUTION: In this fluid pump with a plunger operated by a cam mechanism, the cam mechanism consists of a cam, a roller which slidingly contacts with the cam, and a shoe which slidingly contacts with the cam and abuts on the plunger. Either of the roller or the shoe is made of ceramics with coefficients of thermal expansion nearly equal to that of the other part. For example, one part is made of a ferrous metal, while the other part is made of zirconia ceramics. In the fluid pump having the same structure as the above, at least one of the roller and the shoe is made of silicon nitride ceramic or silicon carbide ceramic. Both ends of the roller are formed into a crown shape, so that the variation of the surface pressure caused by sliding contact between the roller and the cam, in the longitudinal direction of the roller lies in a prescribed range.

摘要： PROBLEM TO BE SOLVED: To provide a bolt tightening apparatus that structurally simply micro-vibrates a bolt at right angles to the bolt axis when tightening the bolt.
SOLUTION: A reducing eccentric cam 16 directly coupled to an input rotary shaft 14 fits peripheral external teeth with internal teeth on an inner circumference of a case 12A. The internal gear 12 synchronously rotates a coaxial, slow rotation rotor 20 via rotation transmission pins 22 to rotate a socket wrench 150, which tightens a bolt 110. A displacement controlling eccentric cam 24 is fixed at the rotation center of the reducing eccentric cam 16 so as to penetrate the rotation center of the slow rotation rotor 20. The displacement controlling eccentric cam 24 holds an axially penetrating displacement controlling pin 26 enclosed with double eccentric rings 24. The external teeth are fewer than the internal teeth. The rotation axes of the input rotary shaft 14 and displacement controlling pin 26 are offset, and the offset is adjusted by the rotational position of the double eccentric rings 24.
