To provide a vehicle shock absorber and a suspension device, which can protect a stroke sensor and reduce costs.SOLUTION: A vehicle shock absorber includes: a shock absorber main body 1 having a cylinder 10, a piston 11 that is axially movably inserted into the cylinder and divides the interior of the cylinder into an extension-side chamber R1 and a compression-side chamber R2, and a rod 12 having one end that is coupled to the piston and is axially movably inserted into the cylinder, and the other end that can be coupled to a wheel side; a reservoir 2 including a reservoir cylinder 13, and a free piston 14 that is axially movably inserted into the reservoir cylinder and divides the interior of the reservoir cylinder into a gas chamber G and a liquid chamber L put in communication with the compression-side chamber R2; and a stroke sensor 3 for detecting stroke displacement of the shock absorber main body. The stroke sensor has a detected element 3c coupled to the free piston, and a rod-like probe 3b that has one end coupled to the reservoir cylinder and is housed in the reservoir cylinder to detect the position of the detected element.SELECTED DRAWING: Figure 1

    【課題】ストロークセンサを保護できるとともにコストを低減可能な車両用緩衝器および懸架装置の提供。【解決手段】車両用緩衝器は、シリンダ10と、シリンダ内に軸方向へ移動可能に挿入されるとともにシリンダ内を伸側室R1と圧側室R2とに区画するピストン11と、一端がピストンに連結されてシリンダ内に軸方向へ移動可能に挿入されるとともに他端が車輪側に連結可能なロッド12とを有する緩衝器本体1と、リザーバ筒13とリザーバ筒内に軸方向へ移動自在に挿入されるとともにリザーバ筒内を気室Gと圧側室R2に連通される液室Lとに区画するフリーピストン14とを備えたリザーバ2と、緩衝器本体のストローク変位を検出するストロークセンサ3とを備え、ストロークセンサは、フリーピストンに連結される被検出子3cとリザーバ筒に一端が連結されるとともにリザーバ筒内に収容されて被検出子の位置を検知するロッド状のプローブ3bとを有している。【選択図】図1
