Abstract:
A rotary slide bearing part of a rotary slide slit bearing for supporting a rotary shaft thereon in a rotatable manner, comprising a first bearing surface portion for arrangement adjacent to a second bearing surface portion of another rotary slide bearing part of the rotary slide slit bearing, a load from the shaft to be borne by the first bearing surface portion being larger than a load from the shaft to be borne by the second bearing surface portion, whereinthe first bearing surface portion includes a fluidal pressure generating surface facing adjacent the shaft to generate a fluidal pressure between the fluidal pressure generating surface and the shaft, a main groove arranged at a circumferential end of the first bearing surface portion adjacent to the second bearing surface portion, and a sub-groove extending in line with and from the main groove in a circumferential direction of the first bearing surface portion, and an axial width of the sub-groove is smaller than that of the main groove.
