[0032]

As is apparent from the above description, in the fuse puller holding structure according to the first aspect of the present invention, the entire fuse puller held laterally on the upper surface of the case is raised upward by the pedestal portion. Therefore, a gap into which the fingertip can be inserted can be formed between the upper surface of the case and the lateral fuse puller, and the fuse puller can be easily removed with the fingertip. Therefore, workability during maintenance is improved.

Further, according to the fuse puller holding structure of the second and fourth aspects, the fuse puller can be held horizontally on the pedestal, and further, by the respective locking portions, positioning in the front-rear direction, detent and upward movement. It can be prevented from coming off and the fuse puller can be securely held without falling off.

Further, according to the fuse puller holding structure of the third aspect, since the pedestal portion is inclined, the clearance between the projecting end of the pedestal portion and the upper surface of the case can be increased without raising the overall holding position of the fuse puller. It is possible to increase the size of the fuse puller, and it is possible to increase the space for inserting the finger when the fuse puller is pulled out.

Further, according to the fuse puller holding structure of the fifth aspect, the outer wall of the fuse accommodating portion can be used as a protective wall, and since both sides of the held fuse puller are protected by the wall, the external member is the fuse puller. It is possible to prevent the fuse puller from being damaged due to the interference with, and the fuse puller from coming off due to the disengagement from the engagement portion.
