摘要: A half bearing is provided with a first groove and a second groove on the inner circumferential surface side. The first and second grooves extend in the circumferential direction of the inner circumferential surface, and retain lubricating oil. The end of the first groove in the circumferential direction, on the downstream side in the rotational direction of the shaft (the end on the crush relief side), is located away from a crush relief so as not to reach the crush relief. Also, the end of the second groove in the circumferential direction, on the downstream side in the rotational direction of the shaft (the end on the crush relief 14 side), is located away from the crush relief so as not to reach the crush relief.

摘要: A sliding member (10) includes a base material (12), a porous sintered layer (14) provided on the base material (12), and a resin layer (16) impregnated into the porous sintered layer (14) and provided on the porous sintered layer (14). In the porous sintered layer (14), a porosity decreases from a second surface (S2) opposite to a first surface (S1) closer to the base material, toward the first surface (S1), the first surface and the second surface each being one of end surfaces in the thickness direction, and a decrease rate of the porosity in the thickness direction (Z) in a first region (E1) occupying 50% or more of the thickness of the porous sintered layer (14) from the second surface (S2) toward the first surface (S1) is larger than a decrease rate of the porosity in the thickness direction (Z) in a second region (E2) other than the first region (E1) in the porous sintered layer (14).

摘要: Included are: a case; a motor provided in the case and having a rotatable shaft; two blowers provided in the case and including impellers that are fixed to a shaft and are capable of being rotated by the motor, the impellers each having multiple blades disposed at predetermined intervals on a circumference of the corresponding impeller; an intake port provided in the case and configured to take air in between the two blowers; and discharge ports provided in the case to each correspond to a one of the two blowers, each configured to discharge the air taken into a corresponding blower through the intake port to the outside. In each of portions that accommodates corresponding one of the two blowers in the case, a side opposite to a side through which air is taken in is sealed off so as to prevent inflow of air.

摘要: An object of the present invention is to provide a technique capable of realizing good wear resistance with a simple structure. A sliding member and a sliding bearing each include a base layer and a coating layer formed on the base layer, the coating layer having a sliding surface with a counterpart member. The base layer is formed of a hard material that is harder than the coating layer, and the average concentration of a diffusion component of the hard material diffused from the base layer is 4 wt % or more in an evaluation range, in the coating layer, in which the distance from an interface with the base layer is 1 μm or more and 2 μm or less.

摘要: A sliding bearing that is disposed in a cylinder block and supports a journal portion of a crankshaft, including: a semi-annular first split bearing having a first circumferential end surface; and a semi-annular second split bearing having a second circumferential end surface. The first and second circumferential end surfaces contact each other, the first split bearing has a same outer diameter as an outer diameter of the second split bearing, the second split bearing has a thickness at a second circumferentially central position that is greater than a thickness of the first split bearing at a first circumferentially central position, the thickness of the first split bearing is decreased from the first circumferentially central position toward the first circumferential end surface, the thickness of the second split bearing is decreased from the second circumferentially central position toward the second circumferential end surface.
