[Prior Art] A pop-out type lock handle device disclosed in Japanese Patent Application Laid-Open No. 102149/1980 has an outer cylindrical body protruding from the front case part, and a locking shaft rod that engages and disengages from a receiving part on the fixed frame side. is attached to the outer cylinder so as to be rotatable but immovable in the axial direction, the inner cylinder fitted into the outer cylinder is provided with a protruding handle, and the spring-biased inner cylinder and the locking shaft are connected via an interlocking rod. A lock for regulating the protruding movement of the handle is inserted into the inner cylinder body from the front opening of the handle, and a latch body whose tip protrudes and retracts from the side through hole of the inner cylinder body is inserted in conjunction with the rotor of the lock. A locking portion is housed in the cylindrical body and engages with the tip of a spring-biased latch body on the side wall of the outer cylindrical body.

Two circumferential receiving grooves are provided in the middle part of the locking shaft, and the front half of the locking shaft is inserted into the cavity of the outer cylinder through the central hole in the rear wall of the outer cylinder, Furthermore, it is inserted into the cavity of the inner cylinder through a central hole in the back wall of the inner cylinder. An E-ring fitted into one circumferential receiving groove located inside the rear wall of the outer cylinder, and an E-ring fitted into the other circumferential receiving groove located outside the rear wall of the outer cylinder. By sandwiching the back wall between the rings, the locking shaft is attached to the outer cylinder while being prevented from moving in the axial direction.

[Problems to be solved by the invention] However, in the conventional device, in the unlocked state in which the handle protrudes, the lock shaft is engaged and supported at the middle part in the central hole in the rear wall of the outer cylinder, and the lock shaft is engaged and supported at the front end in the central hole in the rear wall of the outer cylinder. Although it is engaged and supported by the central hole in the rear wall of the cylinder, there is a gap between the inner peripheral surface of these central holes and the outer peripheral surface of the locking shaft, and the rear wall of the outer cylinder Since there is also a play between the locking shaft and the inner and outer E-rings, there is room for the locking shaft to swing around the center hole, and the play gradually increases due to wear during use. Therefore, the locking shaft may not be correctly aligned on the axis of the outer cylinder.

When the arrangement of the locking shafts is diagonally deviated in this way, the locking shafts and the receiving part may not engage with each other, or it becomes difficult to engage them smoothly.

Therefore, an object of the present invention is to provide a pop-out type lock handle device in which the locking shaft is properly aligned on the axis of the outer cylindrical body, so that the locking shaft and the receiving portion can always be smoothly engaged. .
