A sliding bearingis composed of a pair of halved bearingsand is provided with crush reliefsE,E in positions adjoining abutment surfacesB,B of these halved bearings. Chamfered portionsD,D are formed in inward edge portions of the above-described abutment surfacesB,B, and a dust pocketis formed on the middle side of the chamfered portionsD,D. The relative angle &#x3b1; formed by the above-described crush reliefsE,E with sliding surfacesin positions adjoining the crush reliefsE,E is set at 0.69&#xb0; or more.

Sliding bearing

A sliding bearingis formed cylindrically of a pair of half bearingsand. A dust pocketformed of a recess part is formed in the inner peripheral edges of joining surfacesA andA of the half bearingsand, and foreign-substance discharge groovesand' are formed in a sliding surfacecontinuing from the dust pocket

A sliding bearingis formed into a cylindrical shape by placing abutting surfacesA andA of a pair of half-bearingsandso as to abut against each other. Two foreign substance discharging groovesand' inclined with respect to an axial direction of the sliding bearingare formed on a sliding surfaceadjacent to an inner circumferential edgeof the abutting surfacesA andA. When a lubricant is supplied to the sliding surface, a foreign substancemixed in the lubricant is trapped by foreign substance discharging groovesand&#x2032; and then discharged out of the sliding bearingfrom endsA andB (A&#x2032; andB&#x2032;) open to end facesand

A gear assembly comprising two gears and a spring in the form of a C-shaped clip interconnecting the two gears. Two pins are provided on one of the two gears and the spring has two holes, one in each end thereof, whereby the spring can be carried by one gear in a pretressed state by means of the pin-and-hole connection. The other gear has a groove to cover the spring, thus the assembly work can be accomplished simply by resting the second gear to the first gear. An end wall of the groove engages with an end of the spring to create a spring force necessary to provide non-backlash mating with a third gear.
