  The first cover portion 2 includes an upper surface wall 3 and side wall 4 that is suspended from the three edges of the upper surface wall 3. The first cover portion 2 covers a part of the upper half of the fuse unit 30. The side wall 4 is provided with locking portions 5 at a plurality of locations. Each locking portion 5 is locked to the fuse unit 30. As for the 1st cover part 2, the 2nd cover part 10 side is made into the open surface. The open surface side of the top wall 3 is an inclined surface portion 6 that is inclined downward toward the open end.

  The second cover portion 10 includes an upper surface wall 11 and a side wall 12 that is suspended from an edge of the upper surface wall 11. Unlike the conventional example, the side wall 12 is suspended only from two edges. One side surface of the second cover portion 10 is a notch portion 14 (shown in FIG. 5). The side surface defined as the notch portion 14 is a side surface that is rearward with respect to the moving direction from the normal position in the sliding direction of the second cover portion 10 to the first and second shift positions. The normal position, the first shift position, and the second shift position will be described below.

  The second cover portion 10 covers the upper half of the fuse unit 30, the battery connection terminal 32, and the battery post 31 a at the closed position in the rotation direction and the normal position in the slide direction. The second cover part 10 has an open surface on the first cover part 2 side. The open surface side of the top wall 11 is an inclined surface portion 13 that is inclined downward toward the open end.

  The connecting portion 20 </ b> A is disposed at a position lower than the upper surfaces of the first cover portion 2 and the second cover portion 10. The connecting portion 20 </ b> A includes a bearing portion 21 provided integrally with the first cover portion 2, and a shaft holding rod 22 and a support shaft 23 provided integrally with the second cover portion 10.

  The bearing portion 21 protrudes from the open end of the upper surface wall 3 of the first cover portion 2 toward the opening surface of the second cover portion 10. The bearing part 21 is comprised from three bearing pieces 21a-21c at intervals. Each bearing piece 21a-21c is substantially C-shaped by side view. The support shaft 23 is pivotally supported by fitting the support shaft 23 through the openings of the bearing pieces 21a to 21c.

  The shaft holding rod 22 protrudes from the open end of the upper surface wall 11 of the second cover portion 10. The shaft holding rod 22 is longer than the width dimension of the bearing portion 21 (the width dimension between the bearing piece 21a and the bearing piece 21c at both end positions) and protrudes toward the notch portion 14 of the second cover portion 10. Further, the shaft holding rod 22 has a function as a connecting portion of the conventional example when the second cover portion 10 is rotated.

  Similar to the shaft holding rod 22, the support shaft 23 is longer than the width dimension of the bearing portion 21 (the width dimension between the bearing piece 21 a and the bearing piece 21 c at both end positions) and is on the side of the notch portion 14 of the second cover portion 10. Is protruding. Both end portions of the support shaft 23 are fixed to both end portions of the shaft holding rod 22. The support shaft 23 is disposed with a gap between the support shaft 23 and the shaft holding rod 22 except at both ends. The bearing pieces 21a to 21c of the bearing portion 21 can support the support shaft 23 in a freely rotatable manner by utilizing this gap.

  That is, the second cover portion 10 is rotatable with respect to the first cover portion 2 with the support shaft 23 as a fulcrum, and is slidable. The second cover portion 10 is in a normal position in the sliding direction, and is between a closed position that covers a part of the upper half of the fuse unit 30, the battery connection terminal 32, and the battery post 31a and an open position that exposes them.

The post-fixing bolt 32a is slid between a first shift position (position in FIG. 7) and a second shift position (position in FIG. 8) exposed to the fuse unit fixing bolt 32b.

  Further, the support shaft 23 is provided with first and second stoppers 23a and 23b having circumferential protrusions that slightly protrude from the outer peripheral surface thereof. The first and second stoppers 23a and 23b restrict the movement of the support shaft 23 in the axial direction. However, when a predetermined force or more is applied in the axial direction of the support shaft 23, each of the bearing pieces 21a to 21c is elastically deformed in the diameter-expanding direction and can slide over the first and second stoppers 23a and 23b. The first stopper 23a positions the normal position of the second cover portion 10 as shown in FIG. 6 and the first shift position of the second cover portion 10 as shown in FIG. The second stopper 23b positions the first shift position of the second cover portion 10 as shown in FIG. 7 and the second shift position of the second cover portion 10 as shown in FIG.

The battery cover 1 </ b> A covers the outer periphery of the battery post 31 a, the battery connection terminal 32, and the fuse unit 30.

  When performing parts replacement, inspection, etc., it is necessary to expose the inside of the second cover portion 10. Here, when the peripheral member is not located on the rotation locus of the second cover part 10, the second cover part 10 is rotated around the support shaft 23, and the second cover part 10 is changed from the closed position to the open position. To do. In the rotation of the second cover portion 10, the connecting portion 20 </ b> A is located at a position lower than the upper surfaces of the first cover portion 2 and the second cover portion 10, and therefore can rotate only to a position where both the inclined surface portions 6 and 13 abut. Thereby, the rotation range of the 2nd cover part 10 is controlled by about 90 degree | times.

  When a peripheral member (not shown) is positioned on the rotation locus of the second cover part 10, the second cover part 10 is slid. When the sliding movement is made to the first shift position, the post fixing bolt 32a is exposed as shown in FIG. The battery connection terminal 32 and the fuse unit 30 can be removed as a unit by loosening the post fixing bolt 32a. When sliding to the second shift position, the fuse unit fixing bolt 32b is exposed as shown in FIG. The fuse unit 30 can be removed by loosening the fuse unit fixing bolt 32b.

  Further, if the peripheral member (not shown) is off the rotation locus of the second cover portion 10 at the first shift position or the second shift position, the second cover portion is at the first shift position or the second shift position. 10 can be rotated from the closed position to the open position.

  As described above, the connecting portion 20A of the battery cover 1A is rotatable between the first cover portion 2 and the second cover portion 10, and is rotated between the first cover portion 2 and the second cover portion 10. It is provided so as to be movable in the axial direction. Therefore, as described above, the battery cover 31a, the battery connection terminal 32, and the fuse unit 30 can be exposed as much as possible by moving the second cover portion 10 from the closed position regardless of the arrangement state of the peripheral members (not shown). it can. Thereby, replacement work of the fuse unit 30, the battery connection terminal 32, etc., fuse inspection work, etc. are possible.

  The support shaft 23 of the connecting portion 20 </ b> A is provided with a length that can be moved in the axial direction while being supported by the bearing portion 21. Therefore, the shift amount of the second cover portion 10 can be freely adjusted by adjusting the length of the support shaft 23.

  The second cover portion 10 has a notch portion that avoids interference between the battery post 31 a, the battery connection terminal 32, and the fuse unit 30 on the side surface that is rearward with respect to the moving direction from the normal position covering the internal parts to the shift position. 14 Accordingly, the second cover portion 10 can be slid without being rotated at all.
