向への移動拘束が無意図的に解かれることもない。As described above, in the lock handle device for a removable door according to the present invention, the first receiving groove 9 is formed on the inner surface of the receiving main body 1.
The second receiving groove 10 is provided annularly on the outer surface of the rotor 3 so as to face the first receiving groove 9, and the lateral hole 11 orthogonal to the first receiving groove 9 is opened on the outer surface of the seat body 1. The steel ball 12 inserted from the lateral hole 11 is rollably engaged with the first receiving groove 9 and the second receiving groove 10 so that the rotor 3 is immovably restrained in the axial direction in the receiving main body 1. The hole 11 is closed by the plug 13, and the unbalanced load generated by the engagement and disengagement of the stop plate 6 and the metal receiving portion 23 on the box body 21 side is caused by a plurality of steel balls continuously inserted. Since the rotor 3 is dispersed and supported by the rotor 12, the rotation of the rotor 3 is always smooth, and the rotor 3
Of the O-ring 14 fitted in the annular groove 15 does not lose or deteriorate waterproofness. Further, since the steel balls 12 are both engaged with the first receiving groove 9 and the second receiving groove 10 formed in an annular shape, the steel balls 12 cannot fall off, and the movement of the rotor 3 in the axial direction is restricted. Is not unintentionally unraveled.
