  In addition, even when the main body connecting portion 51 and the closing connecting portion 53 are separated from the case main body 30, the main body connecting portion 51 and the connecting pin 22 remain in an integrated state while being engaged with each other, and the main body connecting portion 51 is Since the state of being engaged with the base connecting portion 55 via the connecting pin 22 is maintained, the main body connecting portion 51 and the closing connecting portion 53 can be connected to the main body even when a nipper or the like is used when the main body connecting portion 51 and the closing connecting portion 53 are removed from the case main body 30 The portion 51 and the connecting pin 22 remain in the fixed base member 40 in an integrated state, and do not scatter from the fixed base member 40, and can be picked with a finger or the like and removed together. When removing 30 from the fixed base member 40, it is possible to prevent the occurrence of scattered matter.

  Further, by moving the main body connecting portion 51 and the closing connecting portion 53 separated from the case main body 30 in the longitudinal direction of the blocking portion 55A (in the direction of arrow β in FIG. 14), the pin locking of the main body connecting portion 51 is performed. The body portion 22A of the connecting pin 22 inserted into the hole 51B can be moved in a direction other than the detaching direction (the direction of the arrow α in FIG. 14), whereby the main body connecting portion 51 and the closing connecting portion 53 can be moved. Can be easily detached from the fixed base member 40. Therefore, the connecting pin 22 can be quickly and easily removed from the fixed base member 40 together with the main body connecting portion 51 and the closing connecting portion 53.

  Further, the case main body 30 is divided into a case base 31 and a case lid 32, a main body connecting portion 51 is provided on the case base 31, a closing connecting portion 53 is provided on the case lid 32, and the closing connecting portion 53 is provided. Since the pin insertion hole 53B through which the twisting portion 22B of the connection pin 22 is inserted is provided, the connection pin 22 that connects the main body connection portion 51 of the case body 30 and the base connection portion 55 of the fixed base member 40, The closing connecting portion 53 can be connected to the main body connecting portion 51, whereby the case main body 30 can be attached to the fixed base member 40 and the case base 31 and the case lid portion 32 can be closed with one connecting pin 22. Therefore, both the number of parts of the main control board case 20 can be reduced, and the assembling work of the main control board case 20 can be simplified.

Further, when the case body 30 is disposed at a predetermined position of the fixed base member 40, the pin locking hole 51B, the blocking portion 55A and the pin insertion hole 53B are arranged along the insertion path of the connecting pin 22, and Since the pin locking hole 51B is disposed at a position deeper than the blocking portion 55A, when the case body 30 is connected to the fixed base member 40, both ends of the connection pin 22 are connected to the pin insertion hole 53B and the pin engagement. The intermediate portion is locked by the blocking hole 51B and the intermediate portion is locked by the blocking portion 55A. As a result, when an external force is applied in a direction away from the fixed base member 40, the external force is applied to the intermediate portion of the connection pin 22, and the deformation amount of the connection pin 22 due to the external force is suppressed, so that the case body 30 and the fixed base member The connection strength with 40 can be easily secured.
On the other hand, when a configuration in which the pin locking hole 51B is arranged at a position closer to the front side than the blocking portion 55A in the insertion path of the connecting pin 22, that is, when a configuration different from the present embodiment is adopted, the connecting pin 22 The leading end portion of the pin is locked to the blocking portion 55A, and the trailing end portion is locked to the pin insertion hole 53B and the pin locking hole 51B. Then, the external force in the direction of separating from the fixed base member 40 is concentrated on the tip of the connecting pin 22, so that the deformation amount of the connecting pin 22 due to this external force cannot be suppressed, and the rigidity of the connecting pin 22 is sufficiently secured. If this is not possible, the connection strength between the case body 30 and the fixed base member 40 may not be sufficiently ensured.

In addition, this invention is not limited to the said embodiment, The deformation | transformation in the range which can achieve the objective of this invention, improvement, etc. are included.
That is, the connecting pin is not limited to the connecting pin 21 in which the end portion 21B is formed at the tip portion. For example, as shown in FIG. 15, the tip portion is branched into two branch portions 25A. The locking holes 25B are formed in each of the branched branch portions 25A, and the locking claw 51D formed on the inner peripheral surface of the pin locking hole 51B of the main body connecting portion 51 has a locking hole. 25B may be a connecting pin 25 to be locked. In short, if it has a locking portion that is deformed so as to be prevented from coming off by the connecting portion when inserted into the connecting portion, the specific shape of the connecting pin and The structure can be appropriately selected for implementation.

Further, in the embodiment, the case base 31 is provided with the main body connecting portion 51 and the case lid portion 32 is provided with the closing connecting portion 53. However, the present invention is not limited thereto, and conversely, the case base 31 is provided with the closing connecting portion 53. The main body connecting portion 51 may be provided on the case lid portion 32.
