Abstract
The present invention provides a shock absorber serving as a cylinder device capable of securing a clearance between an outer tube and a peripheral member and improving bending rigidity of the outer tube. An outer tubehousing an inner tubeis provided with a pair of knuckle bracket fastening platesandprotruding in one direction from an outer surface of the outer tube. The pair of knuckle bracket fastening platesandhas wide surfaces facing each other, and the wide surfaces are provided along an axial direction of the outer tube. When the inside of a vehicle is defined as a virtual region Iand the outside of the vehicle is defined as a virtual region IIwith a virtual line, which passes through a stroke center lineand matches the inside and outside of the vehicle, as a boundary in an orthogonal cross section at an arbitrary axial position of the outer tubeorthogonal to the stroke center lineof a piston rod, a cross-sectional area Aof the outer tubein the virtual region Iis made larger than a cross-sectional area Aof the outer tubein the virtual region II
