Title:
POWER CYLINDER OF POWER STEERING DEVICE
Document Type and Number:
Japanese Patent JP3851514
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve bearing precision of a bearing bush by reducing the deformation of a barrel part when mounting the bearing bush as much as possible.
SOLUTION: An annular flange 17 protruding to the outside in the radial direction is provided at outer periphery on one end side of the cylindrical barrel part 16 of the bearing bush 14, and an annular recessed part 19 with which the annular flange 17 is engaged is provided in the vicinity of an end part on the side where the bearing bush 14 is inserted in a bush fitting part of a sealing plug 12. When mounting the bearing bush 14, the other end part of the barrel part 16 of the bearing bush 14 is inserted into a rod fitting and insertion hole 13 of the sealing plug 12, and the annular flange 17 is deformed at the end of insertion stroke of the bush 14 and is engaged with the annular recessed part 19 of the sealing plug 12 when the bush 14 is pushed into the rod fitting and insertion hole 13 as it is. Consequently, the deformation of the barrel part 16 in accordance with the deformation of the annular flange 17 is performed at the end only of insertion stroke of the bush 14.
