Does not move and is always fixed in a stable position.
Further, since the expansion and contraction of the battery member 3 is restricted, the clamp member 27 is favorably reduced from being loosened by the expansion and contraction of the battery member 3. In addition, in the present embodiment, the clamp member 27 is formed large so as to correspond to the sandwiched portions 5 of the plurality of battery members 3, and thus rattling due to expansion and contraction of the battery member 3 is favorably reduced. .

As shown in FIG. 1, the battery member 3 itself is provided with clamped portions 5 at both ends in the longitudinal direction, and the clamped portions 13 and 29 forming a pair are fixed at predetermined intervals.
Therefore, expansion and contraction due to temperature in the direction connecting the fixed parts of the entire battery member 3 is restricted.

Further, since the elastic member 21 is provided, even if the battery member 3 expands or contracts to some extent, the elastic member 21 can absorb the expansion and contraction and hold the battery member 3 in a stable fixed state. In addition, since the angle formed by the pair of sandwiching portions 13 and 29 is set to an acute angle, even if the battery member 3 is deformed by expansion and contraction, the elastic member 21 can smoothly absorb between the pair of sandwiching portions. You can move to.

Next, a battery fixing member and a battery member according to another embodiment of the present invention will be described with reference to FIGS. In addition, when it is the same as that of the battery fixing member 1 and the battery member 3 shown in FIGS. 1-3, the same code | symbol is attached | subjected to drawing and detailed description is abbreviate | omitted.

The number of processing steps for the lower case 83 can be reduced.
Further, even if the elastic member 89 having a smaller thickness than that in the case of the lower case 11 of FIG. 1 is used, the battery member 75 can be moved by sliding on the first holding portion 85.

Further, FIG. 9 shows an example of a fixing member capable of freely setting the fixing interval of the fixed body. The battery fixing member 101 in FIG. 9 includes a lower case 103 similar to the battery fixing member 1 in FIG. 1 and substantially the same clamp member 27. The first clamping portion 105 of the battery fixing member 101 is formed with a protrusion extending along the longitudinal direction of the first clamping portion 105 to form a fitting portion 107. Further, the battery member 110 is formed in a plate shape like the battery member 3 of FIG. 1, and the clamped portions 113 are provided at both ends of the lower portion. Then, a recessed groove penetrating in a direction perpendicular to the plane of the plate-shaped member is formed in the lower portion of the clamped portion 113 to form a fitted portion 115. The fitted portion 115 is
The size is such that the fitting portion 107 of the first holding portion 105 can be inserted therethrough. An elastic member 117 is provided on the lower surface of the clamped portion 113. The elastic member 117 is a rubber mat-shaped member and is fixed to the battery member 110 in various fixing forms such as adhesion and welding.

In this battery fixing member 101, since the fitting portion 107 is continuously provided along the first holding portion 105, the battery member 110 can be arranged and fixed at an arbitrary portion. Therefore, various numbers of battery members 110 can be arranged and fixed on the lower case 103 at various intervals. Further, since the fitted portion 115 of the battery member 110 is formed so as to extend in the entire sliding direction when the battery member 110 is arranged by sliding, the fitting portion 107 of the ridge is formed by the fitting portion 107 of the ridge.

5 can be moved by sliding. Also in this configuration, the fitting portion 107 and the fitted portion 115 are fitted in the direction perpendicular to the direction connecting the fixed parts,
Expansion and contraction in the direction of connecting the fixed parts of the battery member 110 are well regulated. In addition, since the fitting portion 107 and the fitted portion 115 are fitted to each other even before being fixed by using the clamp member 27, the battery member 11 is more stable.
It is expected that 0 can be placed at a predetermined position.

Although the fitting portions 107 are provided continuously, they may be provided intermittently at a predetermined interval. In this case, the fixed position of the battery member 110 can be set in advance by the position of the fitting portion 107. Even when the fitting portion 107 is provided intermittently, the battery member 110 can be slid and arranged at a predetermined position, as in the case of FIG. 9. That is, in the battery fixing member and the fixed body according to the present invention, since the fitting section and / or the concave section of the fitted section are continuously formed in the sliding direction of the fixed body, Even if the convex portion of the fitted portion is projected, it can be installed at a predetermined portion by sliding movement.

The battery member 43 in which 44 projects from the lower surface can be arranged at a predetermined portion by sliding. In addition, the battery member 110 of FIG.
In the lower case 11 of the battery fixing member 1 shown in FIG. 1, even if the elastic member 21 is formed to have a thickness smaller than that of the fitting portion 15, it can be placed at a predetermined position by sliding.

In the above embodiment, the fitting portion is provided on the first or second holding portion. However, the fitting portion, that is, the fitting structure is the first holding portion and the second holding portion. It is not limited to the form provided between the portion or both of them and the sandwiched portion. It suffices that the held portion of the fixed body is fixed to a predetermined portion of the fixing member. For example, as shown in FIG. 10, the fitting portion is separate from the first and second holding portions. It may be formed.
