Shock absorber

A shock absorber including a cylinder filled with a fluid and a piston valve coupled to a piston rod and configured to partition an inside of the cylinder into a tension chamber and a compression chamber, the shock absorber comprising:

• a support member coupled to an end of the cylinder and provided with a connection flow path;
• a first guide member forming a first pressing chamber and provided with a first flow path formed to vertically pass therethrough;
• a second guide member forming a second pressing chamber and having a second flow path configured to allow the second pressing chamber to communicate with the compression chamber;
• an opening/closing member coupled to an end of the piston rod and provided to press the second guide member upon lowering the piston rod;
• a first elastic member provided between the first guide member and the support member;
• and
• a second elastic member provided between the first guide member and the second guide member,
• wherein an outer circumferential surface of the first guide member is in close contact with an inner circumferential surface of the cylinder,
• wherein the first flow path includes:
• a first main flow path provided in the form of a plurality of cylindrical holes and radially arranged on the first guide member;
• and
• a first slit flow path recessed in a bottom surface of the first guide member to communicate with the first main flow path and extending in the form of a slit toward a central portion of the first guide member,
• wherein the first slit flow path connects at least portions of the first main flow path to each other.
