Shock absorber and saddle-type vehicle

A shock absorber comprising:

• a cylinder which has a first end in an axial direction thereof, said first end being fixed to a vehicle body of a vehicle with a saddle;
• a rod which holds a piston at a first end of the rod, said piston configured to slide in the cylinder, and has a second end being at an opposite side to the first end of the rod;
• a rod holding member that is fixed to the second end of the rod;
• a first damping force generating portion which is fixed to the first end of the cylinder;
• and
• a second damping force generation portion which is disposed to be movable in the axial direction in the cylinder,
• wherein the second damping force generating portion includes:
• a flow path which passes through the piston in the axial direction;
• a valve which opens and closes an opening portion of the flow path;
• and
• an adjustment unit which adjusts a force required to open the valve from an outer side of the rod,
• wherein the adjustment unit includes:
• a first spring which applies a force in a closing direction to the valve;
• a spring receiver which supports a second end of the first spring;
• and
• an adjustment portion which adjusts a position of the spring receiver,
• wherein the adjustment unit further includes a first transmission member which abuts the valve at a first end thereof, is disposed between a first end of the first spring and the valve and transmits the force applied by the first spring to the valve, and
• wherein the second damping force generating portion includes:
• a first support member which is disposed inside the first transmission member and supports a surface of a second end of the valve;
• and
• a second spring whose first end is supported by the first support member, said second spring applying a force in the closing direction to the valve.
