  "textContent": "A shock absorber includes: a shock absorber main body that has an outer tube and a rod movably inserted into the outer tube and can extend and contract; a main passage and a sub passage that communicate in parallel two working chambers provided in the shock absorber main body; a main damping force generation element provided in the main passage; and a sub damping force generation element provided in the sub passage. The main damping force generation element has only a main valve that opens and closes the main passage. The sub damping force generation element has an orifice provided in series with the sub passage, and a sub valve that opens and closes the sub passage and has a valve opening pressure lower than that of the main valve.",
