A sintered bearing is made of a sintered compact containing nickel silver (Cu—Ni—Zn) as a base. In the sintered bearing, P is not added in the sintered compact. Alternatively, a content of P in the sintered compact is less than 0.05 mass % in terms of mass ratio to a total mass. Consequently, crystal grains constituting the sintered compact can be micronized. In particular, in the sintered bearing, an average crystal particle diameter of the crystal grains constituting the sintered compact is 20 μm or less. Consequently, the mechanical strength and the vibration resisting properties can be improved, and the rotation shaft can be prevented from being damaged.

[Problem] To provide a wick manufacturing method capable of facilitating control of a capillary force of a wick. [Solution] A wick manufacturing method according to the present invention includes: a step for feeding raw material powder containing metal powder onto a base; a step for acquiring a sintered body by heating the raw material powder on the base; and a step for rolling the sintered body. Forming the sintered body by heating the raw material powder fed onto the base enables formation of a sheet-shaped sintered body. Rolling the sintered body enables the porosity of the sintered body to be controlled after the sintered body has been formed. Thus, the capillary force of a wick 1 can be controlled.

[Problem] To improve the mechanical strength and vibration resistance of a sintered bearing and to prevent damage to the rotary shaft of the sintered bearing. [Solution] A sintered bearing 20 according to the present invention is formed of a sintered body that uses nickel silver (Cu-Ni-Zn) as a base material. In this sintered bearing 20, P is not added into the sintered body, or alternatively, the P content in the sintered body is less than 0.05% by mass in terms of the mass ratio to the total mass. Consequently, crystal grains constituting the sintered body can be miniaturized. Specifically, the average crystal grain size of the crystal grains that constitute the sintered body in this sintered bearing 20 is 20 μm or less. Consequently, it is possible to improve the mechanical strength and vibration resistance, while preventing damage to the rotary shaft.

Abrégé

4) membrane on a porous surface of an inner surface or on porous surfaces of an inner surface and both end surfaces. Thus, gaps between particles become small because diameters of the particles of material powder of a powder sintered bearing material are approximately even and fine and are even small pores. As a result, sealing pores on the surface due to steam treatment is easy, and dynamic pressure cannot be leaked.
