A male screw (not shown) is inserted through the through hole 58 from the side where
a to 58 d and screwed into the female screw 60. In the conventional case, the female screw is formed in a straight (having the same outer diameter) cylindrical shape, and an inclined groove or a vertical groove in the same direction is formed on the outer peripheral surface of the female screw. On the other hand, according to the above-described configuration of the present embodiment, the female screw 60 has the outer peripheral surface formed into a tapered step-like shape.
The operation of press-fitting into d can be performed easily and reliably.
Also, since the inclined grooves 62a and 62b are formed on the outer peripheral surface of the female screw 60 in the opposite directions above and below the step, the female screw 60 is loosened and rotates together with the male screw even when the operation of screwing or removing the male screw is repeated. As a result, there is no problem that the screwing action is impaired. Therefore, even if an external force is received, there is no danger that the deformation of the housing is promoted by the loosening of the screws and the rattling of the housing. Since the gap 64 is formed, resin dust generated when the female screw 60 is pressed into the holes 54a to 54d surely falls into the gap 64, and the female screw 60 is removed from the holes 54a to 54d.
To a predetermined depth. Therefore, the flange surface 60c of the female screw 60 is reliably connected to the upper end surfaces 56a-1 to 56d-1 of the columnar projections 56a to 56d.
The female screw 60 is not sufficiently inserted into the holes 54a to 54d, and comes into contact with the projections 50a to 50d in a state where the flange surface 60c is lifted up. Does not cause a phenomenon in which the bonding state of the elements becomes defective.
