Claims20
A hydraulic shock absorber, comprising:
- a vehicle body side tube;
- an axle side tube which moves with respect to the vehicle body side tube;
- a hollow rod which is accommodated in the vehicle body side tube and includes a first flow path in which oil flows in an axial direction inside;
- a damping force adjusting unit which adjusts a damping force by adjusting a flow resistance of the oil;
- and
- an enclosure member which is arranged to surround at least a lower end of the rod, wherein
- the enclosure member includes an inflow path which guides oil from the outside to the inside,
- the inflow path is arranged so that an axis of the inflow path deviates from an axis of the rod,
- the inflow path extends so that the axis of the inflow path is perpendicular to the axis of the rod,
- an inner wall of the enclosure member contains an arc in a cross section when cut in a plane perpendicular to the axis of the rod, and
- a hollow tip member having an inner diameter smaller than that of the first flow path and including a second flow path connected to the first flow path inside is provided in a lower end opening of the first flow path.
