<p>PROBLEM TO BE SOLVED: To shorten an axial dimension of a casing and to simplify a drilling process of an oil passage for supplying oil liquid. SOLUTION: Inclined rotation support members 24, 40 are fitted into fitting recess parts 6, 8 of a rear casing 5 and a front casing. Oil passages 28, 44 are opened on inner circumference surfaces 6A, 8A of the fitting recess parts 6, 8 and on outer circumference surfaces 24D, 40D of the inclined rotation support members 24, 40 to provide with a support member side oil passage 30. Since each oil passage 28, 30, 44 is fitted in thickness dimensions of the inclined rotation support members 24, 40 in the each casing 5, 7, the axial dimension of the each casing 5, 7 is shortened. The each oil passage 28, 30, 44 is formed in an L-shape, so that drilling process is executed with less man-hour.</p> |
