Abstract: Fuse cavity structure includes fuses 10, 20 in which each of fusible elements 17, 27 for protecting a circuit from overcurrent is located between terminals 15 or 25, and a housing 59 in which the fuses 10, 20 are mounted; a part of a wall 65 of the housing 59 which partitions the fuse 10, 20 and fuse 10, 20 is removed thereby to form a notch 65H in the wall 65; and space is proved between the fuses 10 or 20. The notch 65H is formed by notching the wall 65 corresponding to at least a part of the fusible portion 17, 27. The fuse 10 has a head portion 13 and jig engagement portions 14a. A groove 80 corresponding to the head portion 13 and the jig engagement portions 14a is provided within the housing 59. A wide-width portion is provided at the groove 80 in correspondence to the width of the head portion 13 of the fuse 10, and a narrow-width portion is provided at the groove 80 in correspondence to the width of the jig engagement portion 14a of the fuse 10 which is narrower than the head portion 13.

Abstract: In a stationary member adapted to be electrically connected with at least one connecting member, a first connecting member is attached to a first connecting part. A cover member is slidable between a first position to lock the first connecting member at the first connecting part and a second position to enable an attachment of the first connecting member to the first connecting part. The cover member is provided with a first engagement member. A second engagement member engages with the first engagement member in a case where the cover member is located at the first position.
