Abstract

PURPOSE: To abbreviate a centering work for cylinder machining and to reduce the machining cost, by forming the engaging recessed parts, which engage with parts of inner-hole circumferential surface of a cylinder body, in the outer circumference of a sleeve.
CONSTITUTION: A sleeve 10 constitutes of a cylindrical fixing part 10a to be cast-in fixed in the inner hole 21 of a main block body 20 and a cylindrical projecting part 10b setting with the inside of a crank case, projecting from the inner hole 21; and two annular engaging recessed parts 11, 12 are formed on the outer circumference of the cylindrical fixing part 10a. At the casting of the body 20, a part of molten metal which forms the body 20 flows into these recessed parts 11, 12 respectively, and the sleeve 10 is engaged with a part of the circumferential surface of the inner hole 21 of the body 20 with its engaging recessed parts 11, 12 and surely fixed. When the sleeve 10 is pushed into a cutting grinder from its one end, the outer circumference of the cylindrical fixing part 10a is cylindrically machined and automatically pushed outside from said grinder after machining, thus the cylindrical machining is easily performed.
