Unit chambers 12 are formed in a plurality of rows and a plurality of stages, and a load control device 13 corresponding to a unit device is housed in each unit chamber 12. Also, in the box body 11,
As shown in FIG. 1, the tubular member 14 is fixed at the upper and lower ends of each unit chamber 12. Each of these tubular members 14
Has a cylindrical shape extending in the vertical direction, and the upper and lower end surfaces of each tubular member 14 are, as shown in FIG.
An annular collar portion 14a is formed so as to protrude inward.

Pivot members 15, 15 are housed in each cylinder member 14 so as to be vertically movable. Each of these pivot members 15
Is composed of a circular plate portion 15a and a hemispherical projection portion 15b.
The spring member 16 is housed in the space therebetween. Each of these spring members 16 is composed of a compression coil spring. As the plate portion 15a of the pivotally supporting member 15 is pressed, the spring member 16 is engaged with the flange portion 14a of the tubular member 14, and the projection 15b is made into the tubular member 14.
It is held in a state of protruding from.
