【Example】

 1 and 2 show the configuration of an embodiment of the present invention. In FIG. 1 and FIG. 2, reference numeral 1 is a slave unit case. Reference numeral 2 denotes a battery housing portion provided in the lower part of the child device case 1. One end surface 3 is integrally formed with a locking rib 4 for engaging the end portion of the rechargeable battery 30, and the other end surface 5 is formed. Leaf spring mounting portions 6 are provided on the lower portions on both sides of the. As shown in FIG. 3, the leaf spring attachment portion 6 is integrally formed on the bottom surface with a locking hole 7 formed in the end surface 5 and at a front side of the locking hole 7 with a predetermined gap. It comprises a fixing rib 8. Reference numeral 9 is a leaf spring, and as shown in FIG. 4, a locking piece 10 for pressing the end of the rechargeable battery 30 from above is provided at the upper part of the central portion 9a, and from there, it extends like wings on both sides and its both ends 9b and 9c are formed by cutting and raising, and have locking claws 11 that can be engaged with the respective locking holes 7 of the end face 5 of the battery housing portion. The both ends 9b and 9c are fitted between the end face 5 of the battery storage part and the fixing ribs 8 and the locking claws 11 are locked in the locking holes 7 to have the locking ribs 4. It is attached so that it is biased toward the end face 3 direction. Reference numeral 12 is a cover that closes the battery housing 2, and a leaf spring pressing rib 13 that presses the leaf spring 9 from the end face 5 side at a predetermined position on the lower surface to restrict elastic deformation in the direction opposite to the biasing direction. It is integrally formed.

Next, the operation of the above embodiment will be described with reference to FIGS. 1 and 5. In the above embodiment, when the rechargeable battery 30 is installed in the battery housing 2, as shown in FIG. 5, one end of the rechargeable battery 30 is locked with the locking piece 10 of the leaf spring 9 in the flat plate. The other end is fitted into the locking rib 4 while pressing the neck 9 in the direction of the arrow P to bend it. As a result, the rechargeable battery 30 is held at its one end side upper surface by the locking rib 4, and the plate strip 9 that presses the end face 3 and the other end of the rechargeable battery 30 while pressing the locking piece 10 from above. Fixed in between. By mounting the cover 12 on the battery housing portion 2, as shown in FIG. 1, the leaf spring pressing rib 13 on the lower surface of the cover 12 presses the leaf spring 9 pressing the rechargeable battery 30, and the elasticity of the leaf spring 9 is reduced. It regulates deformation and prevents deformation in the direction opposite to the urging direction.

When the rechargeable battery 30 is to be removed from the battery housing portion 2, the leaf spring 9 is pressed by the end of the rechargeable battery 30 while the other end is engaged with the locking rib 4. Release and remove.

As described above, according to the above-described embodiment, the locking rib 4 that locks one end of the rechargeable battery 30 is integrally provided on the end surface 3 of the battery storage portion 2, and the end surface 5 that faces the locking rib 4 is provided. Is provided with a leaf spring 9 that has a locking piece 10 that presses the other end of the rechargeable battery 30 from above and presses the end face 3 toward the end face 3 while limiting the upward movement of the rechargeable battery 30. Since it is pressed and fixed to the leaf spring 9, unlike the conventional case where a battery fixing member by screwing is used, it is not necessary to use a tool, and the rechargeable battery 30 can be easily attached and detached. You can

Further, the leaf spring pressing rib 13 is provided on the lower surface of the cover 12 that closes the battery housing portion 2 to prevent the leaf spring 9 that presses the rechargeable battery 30 from elastically deforming. Even if a shock or vibration is received, the pressing state of the leaf spring 9 against the rechargeable battery 30 does not change, and the rechargeable battery 30 can be more reliably fixed.

[0016]
