連結する。 Reference numeral 17 denotes a lock key which is an operating member, and the lock key 17 has a main body 17a interposed between one side plate 13c and a side piece 7d of the cover 7 facing the outside thereof, and specifically, a mounting hole provided in the side piece 7d. 7e, the locking rod direction is regulated by a flange portion 17b at the base, and is secured to the side piece 7d by a locking spring 18, which is a plate spring attached to the inner wall of the side piece 7d. In the embodiment, a pair of arcuate claw pieces 19, 19 are symmetrically provided at the tip of the main body 17a, protruding in the axial direction from the circumference of the main body 17a. The space between 19 and 19 is cut out, and a clearance S is provided therebetween. The front ends of the claw pieces 19, 19 are open and have a length in the axial direction, while an engagement pin 20 protruding in the radial direction is provided at the tip 14d of the horizontal rod portion 14c of the locking rod.
is from the clearance S between the claw pieces 19 and 19 to the claw piece 1
9 and 19, and there is a clearance in the axial direction between the tip 14d and the end of the main body 17a. That is, the two are connected by a kind of loose coupling.

に揺動し、ロツクを解除する。 Next, to describe its function and effect, insert the key into the groove 17c of the key 17 from the outside of the side piece 7d, rotate the key 17 counterclockwise in FIG. 2, and thereby rotate the key 17 in the same direction. Move the pin 2 with the claw piece 19.
0 in the same direction, the locking rod 14 is rotated in the same direction, the hook portion 14b is swung, and the locking piece 12
By engaging and locking the window 12c and releasing the key, the locking rod 14 is swung in the opposite direction by the spring 16 to release the lock.
ところで、ロツクキー１７は側片７ｄの取付孔

ることができ、キーは爪片がピンと接する位置で
ロツクすれば良いこととなる。 By the way, the lock key 17 is installed by fitting it into the mounting hole 7e of the side piece 7d, but there is a clearance that is sufficiently larger than the pin 20 between the claw pieces 19, 19 at the tip of the lock key 17. Assemble so that the clearance and pin 20 engage,
Further, the claw pieces 19, 19 have lengths in the axial direction, so the pin 20 only needs to be within the range of the axial length of the claw pieces 19, 19. As a result, key 17,
Or the pin 20, that is, the locking rod 14 is misaligned in the axial direction,
Also, the radial direction of the key 17 and the pin 20, that is, the locking rod 14
Even if the two parts do not match concentrically, the key can be assembled by absorbing the axial and radial deviation, and the key only needs to be locked at the position where the claw piece contacts the pin. becomes.
従つて係止片と係止杆とを誤差なくしつつ組着

ができ、更に係止杆側からの解除動に上記により
ロツクキーに連動しないためロツクキーの耐久劣
化がなく、これの耐久性を向上せしめ得る。 Therefore, the locking piece and the locking rod can be assembled without errors, and even if an error occurs between the locking rod and the lock key, it can be absorbed between them, and manufacturing variations in these can be avoided. Even if there is an assembly error, it can be assembled while easily absorbing it, making it easier to manufacture, assemble, and adjust.
Cost reduction can be planned. In addition, the above-mentioned clearance of the lock key allows the operating angle of the lock key to be set arbitrarily in addition to the operating angle of the locking rod, and furthermore, since the release movement from the locking rod side is not linked to the lock key, the durability of the lock key is reduced. This can improve its durability.
