(pivotable), a plurality of shafts 13 and 14 are arranged at one end of the cover 2 at spaces in a projecting fashlon.
The shaft 13, as shown in Fig. 6, has a coaxis, and two of such shafts, for example, are arranged in such a manner as to be projected in the same direction perpendicular to the pivoting direction of the cover 2~
On the other hand, a plurality of short recess portions 15 shorter than the length of the shafts forming the shaft coupling and long recess portions 16 equal to or longer than the length of the shafts are formed in one end of the base 1 at spaces in such a manner as to correspond to the shafts 13 and 14, and one ends of the recess portions 15 and 16 are provided with a plurality of shaft inserting portions 17 and 18 for receiving the tips of the shafts 13 and 14.
As is shown in Fi~s. 10(A) ad 10(B), the cover 2 can be backwardly bent in the thick direction thereof, and by back-wardly bending the cover 2, the shaEts 13 and 14 can be in-clined in the bending direction of the cover 2.
As is shown in Figs. 10(A), 10(B) and 10(C), the shaft 14 corresponding to the long recess portion 16 longer than the length of the shafts is inserted into the shaft inserting portion 18 at one end of the recess portion 16 via the recess portion 16. On the other hand, as is shown in Fig. 10(A) and 10(B), the shaft 13 corresponding to the short recess portion 15 shorter than the length of the shafts is inserted , .

into the shaft inserting portion 17 at one end of the short recess portion 15 shorter than the length of the shafts when the shaft 13 is in its inclined state owing to bending motion of the cover 2 in the backward direction, and by restoring the bending cover 2 to its original state upon completion of the insertion of the shaft 13 as shown in Fig. lO(C), the shaft 13 is engaged in the recess portion 15, and an end face 19 of a basic end portion of the shaft 13 is contacted with the other end 20 (end face on the opposite side with respect to the shaft inserting portion 17) of the recess portion 15 in order to prevent the shafts 13 and 14 from slipping out of the shaft inserting portions 17 and 18. At that time, the shaft 14 is loosely inserted into the shaft inserting pprtion 18 within the recess portion 16 with a play formed in the slipping~-out direction.
The shaft inserting portions 17 and 18 are formed in the same construction which is shown in Figs. 9(A) through 9(~).
As is shown in Fig. 9(A) and 9(D), the recess portions 15 and 16 are provided with inclined surfaces 21 and 22 formed at entrance portions o the shafts l~ and 14 and adapted to enlarge the entrance portions. End portions of the recess portions 15 and 16 at the entrance portions of the shaft inserting portions, as shown in Figs. 9(B) and 9(E), are provided with arcuate bearing portions for holding ar-cuate surfaces of the bottom portions of the circular shafts , : . .

.. , : :, 2~3~532 13 and 14 which are engaged with the recess portions 15 and 16, and also with arcuate bearing portions 25 and 26 for holding upper arcuate surfaces of the shafts 13 and 14 by receiving terminal ends of the shafts 13 and 14 penetrating the bearing portions 23 and 24 as shown in Figs. 9tC) and 9~F) and further with bottom surfaces 27 and 28 to be con-tacted with and stopped by the end faces of the shafts 13 and 14 in order to restrict the movement of the shafts 13 and 14 in the same direction and to restrict play in the radial direction of the shafts 13 and l~ by the shaft inserting por-tions 23, 24 and 25, 26.
The short recess portion 15 shorter the length of the shaft is connected with an enlarged recess portion 29,10nger than the shaft formed at the entrance portion of the shaft 13. The enlarged recess portion 29 is long on the opposite side with respect to the shaft inserting portion 17 of the recess portion 15, and a step portion 30 is formed between the recess portion 15 and the enlarged recess Portion 29 there. As is shown in Figs. 10(A) and 10(B), the shaft 13 is inclined in accordance with the backward bending motion of the cover 2 and brought into engagement with the enlarged recess portion 29, the tip of the shaft 13, while supporting the basic end of the shaft 13 by the step portion 30, is in-clined and inserted into the shaft inserting portion 17, and by restoring the bac~wardlY bending state of the cover 2, the - ~ .

shaft 13 is brought into engagement with the recess portion 15. That is to say, it the step 30, which is necessarily formed at the entrance portion of the recess portion 15, ex-ists, it can be practiced without a provision of the enlarged recess portion 29.
Furthermore, in the above-mentioned embodiment, the recess portions 15 and 16 are opened up on the side of an up-per surface of the end portion of the base 1, the cover 2, as shown in Figs. 1, 2 and 10, is backwardly bent in the thick direction thereof in order to be brough t into an erected state with respect to the base 1, and in that state, the shafts 13 and 19 are held to the recess portions 15 and 16 to realize the above-mentioned engagement. As a modified em-bodiment, it may be designed such that the recess portions lS
and 16 are opened up on the side of the end faces of the recess portions 15 and 16, and the sh~fts l~ and 1~1 are en-gaged into the recess portions lS and 16 from thc end face side.
In this way, the cover 2 is pivotably mounted to the base l, a shaft coupling, which is not easily slipped out at any pivoting position is formed, and by closing the cover 2 relative to the base 1, the IC 5 can be held therebetween.
In order to lock the holding state of the IC, for example, the cover 2 is engaged in the IC accommodating section 6, en-gaging projections 31 formed in the vicinity of the free end ,.
.. . .~
2~2~52 portion of the both sides of the cover 2 are snap engaged with projections 32 formed on the corresponding both sides of the IC accommodating section 6, thereby to prevent the cover 2 from being accidentally pivoted in the opening direction.
As is shown in Fig. 12, the carrier carrying the IC 5 is loaded on a table 34, which can be resiliently moved upward and downward, of the socket 10, a contact 35 of the socket 10 is inserted into a contact positioning hole 36, and by in-timately contacting the presser plate 37 with the socket lO
to press the base 1, the contact 35 is resiliently contacted with a contacting piece of the IC 5 through the opening por-tion 2a of the cover 2 as a reaction.
According to the present invention, the cover causes the shafts, while inclining the shafts owing to the backward bending motion of the cover, to be inserted into shaft in-serting portions of corresponding short recess Portions shorter than the length of the shafts, and the shafts are en-gaged in the recessed portions by the restoring motion of the cover to enhance an easy assembly of the shaft coupling.
The shaft coupling can easily be disassembled by rem~ving the shafts from the shaft inserting Portions of the shart recess portions shorter than the length of the shafts while bending the cover again in the backward direction.
Owing to the foregoing arrangement, the cover cannot be inserted into nor removed from the recess portions unless the , , : .:

cover is bent backwardly. Accordingly, there is no such fear as to cause undesirable cancellation of the shaft cou-pling within a range of a pivotal movement of the cover. If the cover is bent backwardly while exhibiting the above-mentioned effect, cancellation of the shaft coupling can easily be realized.
Although the present invention has been described in its preferred form with a certain degree of particularity, it is understood that the present invention can be changed and modified without departing from the spirit and the scope of the invention as hereinafter claimed.

shaft 13 is brought into engagement with the recess portion 15. That is to say, it the step 30, which is necessarily formed at the entrance portion of the recess portion 15, ex-ists, it can be practiced without a provision of the enlarged recess portion 29.
Furthermore, in the above-mentioned embodiment, the recess portions 15 and 16 are opened up on the side of an up-per surface of the end portion of the base 1, the cover 2, as shown in Figs. 1, 2 and 10, is backwardly bent in the thick direction thereof in order to be brough t into an erected state with respect to the base 1, and in that state, the shafts 13 and 19 are held to the recess portions 15 and 16 to realize the above-mentioned engagement. As a modified em-bodiment, it may be designed such that the recess portions lS
and 16 are opened up on the side of the end faces of the recess portions 15 and 16, and the sh~fts l~ and 1~1 are en-gaged into the recess portions lS and 16 from thc end face side.
In this way, the cover 2 is pivotably mounted to the base l, a shaft coupling, which is not easily slipped out at any pivoting position is formed, and by closing the cover 2 relative to the base 1, the IC 5 can be held therebetween.
In order to lock the holding state of the IC, for example, the cover 2 is engaged in the IC accommodating section 6, en-gaging projections 31 formed in the vicinity of the free end ,.
.. . .~
2~2~52 portion of the both sides of the cover 2 are snap engaged with projections 32 formed on the corresponding both sides of the IC accommodating section 6, thereby to prevent the cover 2 from being accidentally pivoted in the opening direction.
As is shown in Fig. 12, the carrier carrying the IC 5 is loaded on a table 34, which can be resiliently moved upward and downward, of the socket 10, a contact 35 of the socket 10 is inserted into a contact positioning hole 36, and by in-timately contacting the presser plate 37 with the socket lO
to press the base 1, the contact 35 is resiliently contacted with a contacting piece of the IC 5 through the opening por-tion 2a of the cover 2 as a reaction.
According to the present invention, the cover causes the shafts, while inclining the shafts owing to the backward bending motion of the cover, to be inserted into shaft in-serting portions of corresponding short recess Portions shorter than the length of the shafts, and the shafts are en-gaged in the recessed portions by the restoring motion of the cover to enhance an easy assembly of the shaft coupling.
The shaft coupling can easily be disassembled by rem~ving the shafts from the shaft inserting Portions of the shart recess portions shorter than the length of the shafts while bending the cover again in the backward direction.
Owing to the foregoing arrangement, the cover cannot be inserted into nor removed from the recess portions unless the , , : .:

cover is bent backwardly. Accordingly, there is no such fear as to cause undesirable cancellation of the shaft cou-pling within a range of a pivotal movement of the cover. If the cover is bent backwardly while exhibiting the above-mentioned effect, cancellation of the shaft coupling can easily be realized.
Although the present invention has been described in its preferred form with a certain degree of particularity, it is understood that the present invention can be changed and modified without departing from the spirit and the scope of the invention as hereinafter claimed.
