Title:
DOUBLE SHAFT STRUCTURE
Document Type and Number:
Japanese Patent JP2018173156
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a double shaft structure capable of suppressing deviation of a position of a cylindrical rotational shaft in a radial direction of rotation, in assembly of a structure where another rotational shaft is inserted into the cylindrical rotational shaft.SOLUTION: On an inner peripheral surface of an input shaft 21, a small-diameter surface 82 is formed on right and left sides of an opposite portion 81, facing an opening 44 of a communication oil passage 43 of a pump drive shaft 32, so as to avoid the opposite portion 81, wherein an inner diameter of the small-diameter surface is smaller than the opposite portion 81. Consequently, the small-diameter surface 82 approaches an outer peripheral surface of the pump drive shaft 32 with respect to the opposite portion 81. Namely, an interval D1 between the small-diameter surface 82 and the outer peripheral surface of the pump drive shaft 32 is smaller than an interval D2 between the opposite portion 81 and the outer peripheral surface of the pump drive shaft 32.SELECTED DRAWING: Figure 1
