The cylinder device is provided with: a piston rod (50), one end side of which is connected to the piston and the other end side of which is inserted through the closing member and extends outside the cylinder; and a buffer member (82) that is provided between the piston and the closing member and that comes into contact with the closing member by the extension of the piston rod (50). The buffer member (82) has: a first member (101); and a second member (102) that is positioned on the inside in the radial direction of the first member (101), that comes into contact with the closing member earlier than the first member (101), that has a lower hardness than the first member (101), and that urges the closing member in parallel with the first member (101) and the second member (102). 缸装置具备：活塞杆(50)，所述活塞杆的一端侧与活塞连结，另一端侧插通于封闭部件并伸出到缸的外部；以及缓冲部件(82)，所述缓冲部件设置在活塞与封闭部件之间，通过活塞杆(50)的伸长而与封闭部件抵接。缓冲部件(82)具有：第一部件(101)；以及第二部件(102)，所述第二部件位于第一部件(101)的径向内侧，相比第一部件(101)先与封闭部件抵接，所述第二部件的硬度比第一部件(101)的硬度小，第一部件(101)和第二部件(102)对封闭部件并列地作用力。
