To provide a liner chuck device for retaining a cylinder liner having a gradient as well as a cylinder liner with a fixed inner diameter.
The liner chuck device includes a second oscillation member 65b moving a second crank pin 59b forward and backward corresponding to forward/backward movement of a shaft second part 21, and a first oscillation member 65a moving a first crank pin 59a forward corresponding to forward movement of a shaft first part 17 through a spring 63 and moving it backward corresponding to backward movement of the shaft first part 17. After the first crank pin 59a presses the liner 5, and then air is supplied, the shaft 2 in which oscillation of the first oscillation member 65a is stopped moves forward while compressing the spring 63, accordingly the second oscillation member 65b oscillates clockwise, and the second crank pin 59b moves forward to abut to a part at which the inner diameter is larger than the one where the first crank pin 59a abuts in an inner diameter part of the liner 5, thus pressing it.
