摘要： Each of an N1 number of protruding portions Pi is placed in a deviation angle range [θ1(2i-1), θ1(2i)] in a first cylindrical coordinate system in which a central axis of a base portion 12 of a first member 10 serves as a z-axis. Each of an N2 number of recessed portions Qj is placed in a deviation angle range [θ2(2j-1), θ2(2j)] in a second cylindrical coordinate system in which a central axis of an opening portion 22 of a second member 20 serves as a z-axis. In the course of relatively rotating the first cylindrical coordinate system and the second cylindrical coordinate system, in a state of the z-axes thereof made to coincide, for an arbitrary k = 1, 2, .. N2, a state S- (k+1) is implemented by the time a state S- (k), in which θ1(2i(k)-1) = θ2(2j(k)-1) and θ1(2i(k))

摘要： Each of an N 1 number of protruding portions P i is placed in a deviation angle range [θ 1(2i-1) , θ 1(2i) ] in a first cylindrical coordinate system in which a central axis of a base portion 12 of a first member 10 serves as a z-axis. Each of an N 2 number of recessed portions Q j is placed in a deviation angle range [θ 2(2j-1) , θ 2(2j) ] in a second cylindrical coordinate system in which a central axis of an opening portion 22 of a second member 20 serves as a z-axis. In the course of relatively rotating the first cylindrical coordinate system and the second cylindrical coordinate system, in a state of the z-axes thereof made to coincide, for an arbitrary k = 1, 2, .. N 2 , a state S - (k+1) is implemented by the time a state S - (k), in which θ 1(2i(k)-1) = θ 2(2j(k)-1) and θ 1(2i(k) ) 2(2j(k)) , transitions to a state S + (k), in which θ 2(2j(k)-1) 1(2i(k)-1) and θ 1(2i(k)) = θ 2(2j(k)) . Here, i (k) = σ 1 ({(k - 1) mod N 1 }+1) (σ 1 : bijection of sequence {1, 2, .. N 1 }, and j(k) = σ 2 ({(k-1) mod N 2 }+1) (σ 2 : bijection of sequence {1, 2, .. N 2 }).

摘要： The present invention provides a thrust sliding bearing in which a dust cover, which covers a piston rod of a thrust-type suspension, is reliably and simply assembled to a lower case superimposed over an upper case, and the mold structure during the molding of the lower case is simple. Provided is a thrust sliding bearing (100) in which: a lower case (120), which rotatably slides around an axial center (C) of an upper case (110), has a plurality of upper tongue pieces (123) that engage with case-side protuberances (113b) of the upper case (110), and a plurality of lower tongue pieces (124) that engage with cover-side protuberances (Da1) of a dust cover (D); and the upper tongue pieces (123) and the lower tongue pieces (124) of the lower case (120) protrude along an axial center (C) of an inner peripheral surface (122a) of a cylinder part (122) provided to the lower case (120), so that the protuberances do not overlap each other along the axial center (C).

摘要： Provided are: a slide bearing configured so that degradation in sliding performance caused by the entry of dust, muddy water, etc. can be prevented at low cost; and a strut-type suspension using the slide bearing. A slide bearing (1) is provided with: an upper case (2); a lower case (3) joined to the upper case (2) in a pivotal manner and forming an annular space (5) between the upper case (2) and the lower case (3); and an annular center plate (4) disposed in the annular space (5). An annular lip (43) is formed integrally at the outer peripheral edge (423) of the flange (42) of the center plate (4). The lip (43) is in contact, while deflecting, with an annular protrusion (252) formed in an annular groove (24) in the upper case (2) and covers a thrust bearing surface (422) and a thrust supporting surface (251).

摘要： Provided is a slide bearing capable of retaining strength while achieving weight reduction and cost-cutting.
The slide bearing has an upper case (2) to be attached to an upper support for attaching a suspension to a vehicle body, a lower case (3) rotatably combined with the upper case (2), an annular center plate (4) located between the upper case (2) and the lower case (3), and an annular sliding sheet (5) located between the upper case (2) and the center plate (4). The lower case (3) has a lower case body (31) in a substantial cylindrical shape, a flange part (32) projecting radially outward from an outer peripheral surface of the lower case body (31), and hollow sections (321) formed on an outer peripheral surface of the flange part (32). A plurality of the hollow sections (321) are formed at equal intervals in a circumferential direction on the outer peripheral surface of the flange part (32).-

摘要： Provided is a thrust bearing for vehicles, which is configured so that: the direct contact between an annular recess and an annular protrusion, which form a labyrinth structure between an upper case and a lower case, is avoided to prevent torque from increasing and noise from occurring; and lubricating oil present in the thrust bearing is prevented from leaking. A thrust bearing (100) for vehicles is configured so that a labyrinth structure (RB) comprising an annular recess (121b) and an annular protrusion (111ba), which are formed concentric with an upper case (110) and a lower case (120), is formed on the case outer peripheral side or the case inner peripheral side of the portion where the upper case (110) and the lower case (120) are in direct or indirect contact with each other, a labyrinth spacer member (140) for preventing the direct contact between the annular recess (121b) and the annular protrusion (111ba) is disposed between the annular recess (121b) and the annular protrusion (111ba), and the labyrinth structure (RB) reduces sliding resistance during relative pivoting to a level lower than that in the case where the annular recess (121b) and the annular protrusion (111ba) are in direct contact with each other.

摘要： Provided is a slide bearing of lower cost that is capable of preventing the intrusion of dust, muddy water, etc. and has good sliding performance. In a ring-shaped space (5) formed by assembling an upper case (2) with a lower case, a ring-shaped outer dust seal part (42), which bends with one end (420) contacting the upper case (2) and the other end (421) contacting the lower case, is disposed on the outside of a ring-shaped thrust bearing part (40), and the outer dust seal part (42) is connected to the thrust bearing part (40) by connecting parts (43) that extend radially outward from the outside of the thrust bearing part (40), integrating the two as a dust seal-integrated center plate (4). Disposed between the thrust bearing part (40) and the upper case (2) is a ring-shaped lubrication sheet (6), which has surfaces (62, 63) that slide on the mating surfaces facing same.
