置。 A first passage and a second passage are formed in the main body, and the first passage
A passage communicates with the interior of the cylinder, a valve chamber with a first valve body interposed between the two passages is provided, and a small spring is attached to the first valve body to normally bias the valve in the valve closing direction. A bypass passage is formed that constantly communicates the second passage with the valve chamber, and a second valve body whose passage cross section can be adjusted is interposed in the bypass passage, and the second valve body is connected to the first valve body. A lever member in contact with the main body is attached to the main body, and a large spring is interposed between the main body and the lever member to bias and hold the first valve body in the valve open position against the small spring. A contact member is provided that operates the lever member against the large spring near the end position of the fluid discharge stroke of the cylinder, and when the lever member is operated, the first passage and the second passage are shut off by the first valve body. A cylinder shock absorbing device characterized by:
