Abstract: A bracket of a cylinder device includes: a tubular portion having a C-shaped cross section, holding an outer periphery of the outer shell, and having a slit in a front portion; and a pair of mounting portions and protruding outward in the radial direction from both ends of the tubular portion in the circumferential direction. The tubular portion includes a hole formed to permit insertion of the protrusion, from at least one side portion to the back portion of the tubular portion.

Abstract: A hydraulic shock absorber includes: an expansion-side passage and a contraction-side passage that connect an expansion-side chamber with a contraction-side chamber; an expansion-side valve body configured to open or close the expansion-side passage; a contraction-side valve body configured to open or close the contraction-side passage; an expansion-side back-pressure chamber configured to bias the expansion-side valve body; a contraction-side back-pressure chamber configured to bias the contraction-side valve body; a communicating channel that communicates with the expansion-side back-pressure chamber through an expansion-side resistance element, the communicating channel communicating with the contraction-side back-pressure chamber through a contraction-side resistance element; an expansion-side pressure introduction passage that connects the expansion-side chamber with the contraction-side back-pressure chamber; a contraction-side pressure introduction passage that connects the contraction-side chamber with the expansion-side back-pressure chamber; a regulating passage connected to the communicating channel; and a solenoid pressure control valve provided in the regulating passage to control a pressure in the upstream of the regulating passage. An expansion-side load for biasing the expansion-side valve body by virtue of the pressure of the expansion-side back-pressure chamber is larger than a contraction-side load for biasing the contraction-side valve body by virtue of the pressure of the contraction-side back-pressure chamber.

Abstract: A damping valve includes a valve disc, a ring-shaped leaf valve, and a biasing mechanism. The valve disc includes a passage and a valve seat. The valve seat surrounds an exit end of the passage. The leaf valve is stacked on the valve disc. The leaf valve separates from and is seated on the valve seat to open and close the passage. The biasing mechanism causes a variable biasing force to act on the leaf valve to the valve disc side. The entire leaf valve is configured to axially retreat with respect to the valve disc. A clearance is formed between the leaf valve and the valve seat in a state in which the leaf valve is stacked on the valve disc with no load.
