To provide a handle device having a cylinder lock capable of recessing a knob during non-operation and projecting out the knob during operation so as to be pinched.

A handle device having a cylinder lock comprises a cylinder lock 1 fitted in a cylinder 4 in a manner of rotating a plug 5 in its turning direction and of linking or detaching the plug 5, a cylinder case 2 with a cylinder lock 1 fitted in a sliding and reciprocating manner in axial direction under exertion of a spring 23 and also in non-rotatable manner in its direction of rotation and a latch bolt 3 housed in sliding and reciprocating manner under the exertion of a spring 27 in the radial direction of these between the rear end portion of the cylinder lock 1 and the rear end portion of the cylinder case 2. When the plug 5 is turned by a predetermined angle by a key, the latch bolt 3 retreats against the exertion by the spring 27, a linking porting 28 of the latch bolt 3 is released from a receiving hole 30 for the cylinder case 2 to which the linking portion 28 of the latch bolt was linked, and the cylinder lock 1 moves forward by the exertion of the spring 23 an knob portion 9 of the cylinder lock 1 is projected out forwards.
