[Embodiment 1]
FIG. 1 is an explanatory diagram illustrating a configuration of an electronic device. In the present embodiment, description will be given by taking the substantially rectangular plate-type electronic device 1 such as a smartphone or a music player as an example. The electronic device 1 includes a touch panel 2 on one surface. In FIG. 1, the internal configuration of the electronic device 1 is illustrated by separating and illustrating the electronic device 1 and the touch panel 2. FIG. 2 is an exploded perspective view of the electronic device 1. The configuration of the electronic device 1 will be described with reference to FIGS. 1 and 2.

  The electronic device 1 includes a substantially rectangular box-shaped casing 3, a substantially rectangular plate-shaped battery 4, a first elastic portion 61, and a second elastic portion 62 in addition to the touch panel 2 described above. The longitudinal direction of the housing 3 and the longitudinal direction of the battery 4 are the same. The battery 4 has a first surface 41 that is an end surface on the short side, a second surface 42 that is parallel to the first surface 41, and a third surface 43 that is one wide surface. The third surface 43 is provided with a lubricious coating such as a fluorine-based resin. An FPC (Flexible Printed Circuits) 48 connected to the positive and negative electrodes of the battery 4 extends from the end of the battery 4.

  Various electronic circuits such as a receiver 33 that receives radio waves and a circuit that controls the touch panel 2 are arranged inside the housing 3. 1 and 2, illustration of a cable or the like that connects the touch panel 2 and the control circuit is omitted.

  A battery housing portion 5 capable of housing the battery 4 is provided inside the housing 3. The battery accommodating part 5 and the part in which the above-mentioned various electronic circuits are arranged are partitioned by a partition wall. A plurality of bottom surface protrusions 52 are provided on the bottom surface 51 of the battery housing part 5. The bottom protrusion 52 is a substantially hemispherical smooth protrusion. The protruding height of the bottom protrusion 52 is, for example, less than 0.5 mm.

  The battery 4 is housed inside the battery housing portion 5 with the third surface 43 facing the bottom surface 51 side. The mass of the battery 4 occupies several tens percent of the mass of the entire electronic device 1. The third surface 43 contacts the top of the bottom protrusion 52. Since the contact area between them is small and the third surface 43 is provided with a lubricious coating, the battery 4 can easily slide along the bottom surface 51 inside the battery housing portion 5.

  The 3rd surface 43 and the bottom face protrusion 52 are examples of the 1st sliding part of this Embodiment. The first sliding part may be provided on the touch panel 2 side of the battery 4. The first sliding part may be provided on both wide surfaces of the battery 4.

  The bottom protrusion 52 is not limited to a hemispherical shape. For example, it may be a semi-cylindrical hook-shaped protrusion arranged parallel to the longitudinal direction of the bottom surface 51. A lubricious coating may be applied to the bottom surface 51, and a protrusion that reduces the contact area may be provided on the third surface 43 side. Both the bottom surface 51 and the third surface 43 may be flat surfaces provided with a lubricious coating. One or both of the portion including the bottom surface 51 of the housing 3 and the exterior member of the battery 4 may be made of a highly lubricious material such as PTFE (Polytetrafluoroethylene) or POM (Polyoxymethylene).

  A connector 31 is disposed in the vicinity of the battery housing 5. As shown in FIG. 1, the end of the FPC 48 is connected to the connector 31. Power is supplied from the battery 4 to the electronic circuit in the housing 3 and the touch panel 2 via the FPC 48 and the connector 31. Further, a signal for managing and controlling the state of the battery may be transmitted between the battery 4 and the electronic circuit in the housing 3 via the FPC 48 and the connector 31.

  The first elastic part 61 and the second elastic part 62 are compression coil springs that support the battery 4. The first elastic portion 61 is disposed in a compressed state between the first surface 41 and the inner surface facing the first surface 41 of the battery housing portion 5. The second elastic portion 62 is disposed in a compressed state between the second surface 42 and the inner surface facing the second surface 42 of the battery housing portion 5. The battery 4 stops at a position where the pressing force received from the first elastic portion 61, the pressing force received from the second elastic portion 62, and the gravity applied to the battery 4 are balanced.

  The first surface 41 and the second surface 42 may be provided with protrusions or depressions that engage with the ends of the first elastic portion 61 and the second elastic portion 62. Similarly, protrusions or depressions that engage with the ends of the first elastic part 61 and the second elastic part 62 may be provided on the inner surface of the battery housing part 5. The end portions of the first elastic portion 61 and the second elastic portion 62 may be fixed to one or both of the inner surfaces of the battery 4 and the battery housing portion 5 by adhesion or the like.

  The first elastic part 61 and the second elastic part 62 may be configured by arranging a plurality of compression coil springs in parallel. The first elastic part 61 and the second elastic part 62 may be leaf springs. The first elastic part 61 and the second elastic part 62 may be rubber blocks.

  FIG. 3 is an explanatory diagram for explaining a state when the electronic apparatus 1 is dropped. In an electronic device 1 that a user often holds with one hand, such as a smartphone, the center of gravity W is often located at the center of the electronic device 1 as shown in FIG. FIG. 3A to FIG. 3C are schematic views showing the moment when the electronic device 1 falls and the corners of the electronic device 1 come into contact with the horizontal floor.

  FIG. 3A shows a case where the electronic device 1 falls in a posture in which the angle formed between the floor surface and the end surface on the long side is smaller than the angle formed between the floor surface and the end surface on the short side. A point where the electronic device 1 and the floor first contact each other is indicated by p. The intersection of the vertical line passing through the center of gravity W and the floor is indicated by q. The distance between point p and point q is denoted by d. At point p, the impact force applied to the electronic device 1 from the floor is indicated by F. The impact force F is a force in a direction perpendicular to the floor. The magnitude of the impact force F is represented by | F |.

  An angle formed by a vertical line passing through the center of gravity W and a straight line connecting the center of gravity W and the point p is denoted by θ. The larger d is, the larger θ is. As shown in FIG. 3A, the impact force F is divided into a force F1 directed toward the center of gravity W and a force F2 orthogonal to F1. The force F1 acts in the direction in which the electronic device 1 is compressed, causing the touch panel 2 to break, the disconnection due to the distortion of the circuit board, and the like, causing the electronic device 1 to be damaged. The force F2 rotates the electronic device 1 about the center of gravity F. The size | F1 | of F1 is expressed by equation (1), and the size | F | of F2 is expressed by equation (2).

| F1 | = | F | cosθ (1)
| F2 | = | F | sinθ (2)

  FIG. 3B shows a case where the electronic device 1 falls in a posture in which the surface on the touch panel 2 side is directed obliquely upward or obliquely downward. In the case shown in FIG. 3B, the magnitude | F | of the impact force F is greater than that shown in FIG. 3A even when the electronic device 1 drops due to air resistance and drops from the same height. It may be slightly smaller.

  FIG. 3C shows a case where the electronic device 1 falls in a posture in which the angle formed by the floor surface and the end surface on the long side is larger than the angle formed by the floor surface and the end surface on the short side. In the case shown in FIG. 3C, the air resistance acting on the electronic device 1 is small, and the magnitude | F | of the impact force F is slightly larger than that shown in FIGS. 3A and 3B even when falling from the same height. There is a big possibility.

  In the case shown in FIG. 3C, θ is smaller than in the case shown in FIGS. 3A and 3B. Therefore, even if the magnitude of the impact force F is the same, as can be seen from the equation (1), the force F1 that causes damage to the electronic device 1 is larger than that shown in FIGS. 3A and 3B. Further, the impact force F itself is slightly larger than that shown in FIGS. 3A and 3B due to the influence of air resistance.

  As described above, the electronic device 1 is most easily damaged when it is dropped with the end surface on the short side facing downward as shown in FIG. 3C. Hereinafter, a case where the electronic device 1 is dropped in the posture illustrated in FIG. 3C will be described as an example.

  FIG. 4 is an explanatory diagram for explaining a state when the electronic device 1 is dropped. In FIG. 4, illustration of the touch panel 2 and the like is omitted, and behaviors of the housing 3, the battery 4, the first elastic portion 61, and the second elastic portion 62 are schematically shown. FIG. 4A is a schematic diagram illustrating a state at the moment when the electronic device 1 contacts the horizontal floor.

  FIG. 4B is a schematic diagram illustrating a state at a time slightly after FIG. 4A. The housing 3 stops when it comes into contact with the floor. The battery supported by the first elastic part 61 and the second elastic part 62 continues to drop due to inertia. The first elastic part 61 contracts, and the force with which the first elastic part 61 presses the battery 4 increases. The second elastic portion 62 extends and the force with which the second elastic portion 62 presses the battery 4 decreases. Due to the force received from the first elastic part 61 and the second elastic part 62, the dropping speed of the battery 4 gradually decreases, and the dropping ends.

  FIG. 5 is an explanatory diagram for explaining the impact force that the electronic device 1 receives when dropped. FIG. 5A is a comparative example showing the impact force when the battery 4 is fixed to the battery housing part 5 without the first elastic part 61 and the second elastic part 62. FIG. 5B shows the impact force received by the electronic device 1 of the present embodiment. 5A and 5B, the horizontal axis represents time, and the vertical axis represents the magnitude of impact force received by the electronic apparatus 1 at the point p described with reference to FIG.

  The magnitude of the impact force depends on the mass of the electronic device 1, the height of the electronic device 1, the rigidity of the electronic device 1 itself, the material of the floor, etc. in addition to the attitude of the electronic device 1 described with reference to FIG. Is also different. FIG. 5 schematically shows temporal changes in impact force.

  Time t0 indicates the moment when the electronic device 1 touches the horizontal floor. While both the electronic device 1 and the floor are elastically deformed, the electronic device 1 stops dropping. Time t1 indicates the time when the impact force applied to the point p is maximized. Thereafter, the posture of the electronic device 1 changes due to the action of the component force F2 in the direction of rotating the electronic device 1 described with reference to FIG. 3, and the floor is generally set with the touch panel 2 on the upper surface or the lower surface. Land on and stabilize. In FIG. 5, the impact force applied to the point p after the attitude of the electronic device 1 changes is not considered.

  In the comparative example shown in FIG. 5A, an impact force depending on the entire mass of the electronic device 1 is applied to the point p at time t1. In the present embodiment shown in FIG. 5B, at time t1, the impact force depending on the portion excluding the mass of battery 4 out of the mass of electronic device 1 is applied to point p. Therefore, in the present embodiment, the impact force at time t1 is smaller than that in the comparative example.

  In the comparative example, the impact force applied to the point p after time t1 decreases rapidly. In the present embodiment, the second peak of the impact force occurs at time t2 as the battery 4 ends dropping. Since the first elastic part 61 and the second elastic part 62 reduce the falling speed of the battery 4, the time t2 is sufficiently delayed from the time t1, and the two peaks are separated as shown in FIG. 5B.

  5A and 5B, the time integral of the impact force, that is, the area of the portion surrounded by the horizontal axis and the graph line is equal.

  As described above, in the present embodiment, the peak of the impact force due to the drop is distributed twice at the time t1 corresponding to the portion excluding the battery 4 and the time t2 corresponding to the battery. Arise. Since the peaks are separated when the time t1 and the time t2 are sufficiently separated from each other, the maximum value of the impact force is significantly reduced.

  In addition, when the impact force beyond the limit which the electronic device 1 can endure arises, the touch panel 2 or the housing | casing 3 cracks, the fracture | rupture of the wiring of an electronic circuit, etc. will arise, and the electronic device 1 will be broken. By reducing the maximum value of the impact force, the risk of damage to the electronic device 1 is reduced.

  According to the present embodiment, it is possible to provide the electronic device 1 that is not easily damaged when dropped. Since the damage prevention mechanism of the present embodiment is based on a mechanical configuration, it operates effectively even when the electronic device 1 is powered off.

  The first elastic part 61 and the second elastic part 62 may support the end faces on both sides in the short direction of the battery 4. The longitudinal direction of the electronic device 1 and the longitudinal direction of the battery 4 may be in different directions.

  The first elastic part 61 and the second elastic part 62 may also serve as connection terminals connected to the positive electrode and the negative electrode of the battery 4. In this case, the FPC 48 and the connector 31 are used only for transmission of signals for managing the state and controlling the battery 4. When transmission of these signals is unnecessary, the electronic device 1 does not have the FPC 48 and the connector 31.

  The battery 4 is not limited to a substantially rectangular plate shape. As long as the dimensions and shape can be incorporated in the electronic device 1, it may be a rectangular parallelepiped type, a cubic type, a cylindrical type such as an AA type dry battery, or a disk type such as a so-called button type battery. When the battery 4 is a cylindrical type or a disk type, the first elastic part 61 and the second elastic part 62 can realize stable support by supporting both end faces of the battery 4.

  The electronic device 1 may have a plurality of batteries 4. It is desirable that at least the heaviest battery is supported by the first elastic portion 61 and the second elastic portion 62. It is further desirable that all the batteries are supported by the first elastic part 61 and the second elastic part 62, respectively.

  The electronic device 1 is not limited to a substantially rectangular plate shape. The electronic device 1 is an arbitrary electronic device 1 that is carried and used by a user, such as a so-called two-fold type mobile phone, a wearable device such as a wristwatch type or a glasses type, a digital camera, a portable game machine, or a handy terminal. There may be.

[Embodiment 2]
The present embodiment relates to an electronic device 1 that supports a battery 4 on each of four side surfaces. Description of portions common to the first embodiment is omitted.

  FIG. 6 is an explanatory diagram illustrating the configuration of the electronic device 1 according to the second embodiment. In the present embodiment, the first surface 41 is an end surface on the long side of the battery 4 located on the left side of FIG. The second surface 42 corresponds to the back side of the first surface 41. Two first elastic portions 61 are disposed between the first surface 41 and the inner surface of the battery housing portion 5 that faces the first surface 41 with a space therebetween. Two second elastic portions 62 are arranged between the second surface 42 and the inner surface of the battery housing portion 5 that faces the second surface 42 with a gap therebetween.

  A third elastic portion 63 is disposed between the fourth surface 44 that is the end surface on the short side of the battery 4 and the inner surface that faces the fourth surface 44 of the battery housing portion 5. A fourth elastic portion 64 is disposed between the fifth surface 45 corresponding to the back side of the fourth surface 44 and the inner surface facing the fifth surface 45 of the battery housing portion 5.

  According to the present embodiment, even when the electronic device 1 falls with the short side facing down, the impact force is similarly distributed even when the long side falls with the long side facing down. The electronic device 1 that can prevent damage due to falling can be provided.

[Embodiment 3]
The third embodiment relates to an electronic device 1 having a tactile feedback function. Description of portions common to the second embodiment is omitted. FIG. 7 is an explanatory diagram illustrating the configuration of the electronic device 1 according to the third embodiment.

  The actuator 8 is disposed between the first surface 41 of the battery 4 and the inner surface facing the first surface 41 of the battery housing portion 5. The actuator 8 has a stator 81, a mover 82 and a wire 83. The stator 81 is fixed to the inner wall of the battery housing part 5. The mover 82 is in contact with the first surface 41. The contact surface between the moving element 82 and the first surface 41 is provided with a lubricious coating so as to be slidable.

  FIG. 8 is an explanatory diagram illustrating the configuration of the actuator 8. FIG. 8A shows the actuator 8 in a non-operating state. The stator 81 has a substantially square bar shape, and includes stator convex portions 811 and stator concave portions 812 that are alternately arranged along one side surface. The top part of the stator convex part 811 is a smooth substantially semi-cylindrical surface.

  The mover 82 is also substantially rectangular and has mover projections 821 and mover recesses 822 that are alternately arranged along one side surface. The top of the mover convex portion 821 is a smooth substantially semi-cylindrical surface. The stator recess 812 has a shape corresponding to the mover protrusion 821, and the mover recess 822 has a shape corresponding to the stator protrusion 811. The mover 82 is arranged such that the stator recess 812 and the mover protrusion 821 face each other with a gap therebetween, and the mover recess 822 and the stator protrusion 811 face each other with a gap therebetween.

  The wire 83 is disposed between the stator 81 and the mover 82 along the arrangement direction of the stator convex portion 811 and the stator concave portion 812. The wire 83 is made of a shape memory alloy. The wire 83 is instantaneously shortened by about 4 to 5 percent when the temperature exceeds the transformation point, and returns to its original length when the temperature falls below the transformation point. The transformation point of the wire 83 used in this embodiment is about 70 ° C. to 100 ° C.

  The wires 83 are alternately in contact with the mover protrusions 821 and the stator protrusions 811 in a state where a slight tension is applied. Both ends of the wire 83 are connected to terminals 86 provided on the stator 81. Both ends of the wire 83 are connected to the wiring member 87 via terminals 86. As shown in FIG. 7, the wiring member 87 penetrates the inner wall of the battery housing portion 5 and is connected to an actuator control board (not shown). The actuator control board may be arranged in the battery housing part 5.

  The stator 81 and the moving element 82 are non-conductive at least at the part in contact with the wire 83. The terminal 86 and the stator 81 are insulated. Therefore, the wire 83 is insulated from the stator 81 and the mover 82.

  The stator 81 and the mover 82 are made of a material having high thermal conductivity. The material of the stator 81 and the mover 82 is, for example, a metal such as aluminum or copper, or a ceramic such as aluminum nitride or silicon nitride.

  The surface of the stator 81 on the side opposite to the mover 82 is a flat surface and is fixed to the inner wall of the battery housing 5. The surface of the mover 82 opposite to the stator 81, that is, the mover top surface 823 is a flat surface and is pressed against the first surface 41 of the battery 4. The slider top surface 823 and the first surface 41 are provided with a lubricious coating and are slidable. The mover top surface 823 and the first surface 41 are examples of the second sliding portion of the present embodiment.

  In addition, the protrusion which reduces a contact area may be provided in either one of the slider top surface 823 or the first surface 41. One or both of the part including the mover top surface 823 of the mover 82 and the exterior member of the battery 4 may be made of a highly lubricious material such as PTFE or POM.

  FIG. 8B shows the actuator 8 in operation. By applying a pulse voltage to both ends of the wire 83 through the wiring member 87, the wire 83 generates heat instantaneously due to Joule heat. The wire 83 is instantaneously shortened when the temperature exceeds the transformation point. By shortening the wire 83, the moving element 82 moves away from the stator 81 as shown in FIG. 8B.

  Returning to FIG. As the pulse voltage ends, Joule heat generation stops. The heat generated in the wire 83 is dissipated to the outside through the stator 81 and the mover 82, and the temperature of the wire 83 falls below the transformation point. The length of the wire 83 is restored.

  FIG. 8C shows the actuator 8 in a state where an external force is applied in such a direction as to press the moving element 82 against the stator 81. In the state of FIG. 8C, no voltage is applied across the wire 83. The wire 83 extends due to elastic deformation, and the gap between the stator 81 and the mover 82 becomes narrow. Due to the elasticity of the wire 83, a force that pushes back against an external force acts between the stator 81 and the moving element 82.

  In this way, by applying an external force in a direction in which the mover 82 of the actuator 8 is pressed against the stator 81, a force that resists the external force acts on the mover 82. When the external force is lost, the actuator 8 returns to the state described with reference to FIG. 8A. This is a situation just like a compression coil spring, and the actuator 8 has a function similar to that of an elastic body even when it is not energized.

  Returning to FIG. 7, the description will be continued. The actuator 8 functions as an elastic portion disposed between the first surface 41 and the inner surface facing the first surface 41 of the battery housing portion 5 when no voltage is applied. When an operation on the touch panel 2 is received, a pulse voltage is applied to both ends of the wire 83 through the wiring member 87. When the wire 83 contracts, the moving element 82 moves instantaneously in a direction away from the stator 81. Pushed by the mover 82, the battery 4 instantaneously moves toward the second elastic portion 62. With the end of the pulse voltage, the length of the wire 83 is restored. The battery 4 and the mover 82 are pushed back by the second elastic portion 62 and return to the state before the pulse voltage is applied.

  As the battery 4 moves, the entire electronic device 1 shakes instantaneously. A user who operates the touch panel 2 with the electronic device 1 feels a feeling that the electronic device 1 is shaken by the operation of the touch panel 2, that is, a tactile feedback for the operation of the touch panel 2.

  When a telephone call or mail arrives via the receiving unit 33, a pulse voltage having a predetermined interval and the number of times is applied to both ends of the wire 83 via the wiring member 87. The mover 82 and the battery 4 move in conjunction with the pulse voltage. Thereby, the whole electronic device 1 shakes in a predetermined pattern. As described above, notification of incoming calls by vibration can be realized.

  When the electronic device 1 falls, the actuator 8 performs the same function as the first elastic portion 61 of the second embodiment. Since the mover 82 and the first surface 41 of the battery 4 are slidable, the battery 4 can also operate in the longitudinal direction. Therefore, the actuator 8, the second elastic portion 62, the third elastic portion 63, and the fourth elastic portion 64 disperse the impact force and prevent damage due to dropping.

  According to the present embodiment, it is possible to provide an electronic device 1 that is not easily damaged by dropping and that has a tactile feedback function. Since the actuator 8 that provides tactile feedback also functions as an elastic portion that prevents damage due to dropping, the small electronic device 1 having two functions of preventing damage and tactile feedback can be realized.

[Embodiment 4]
The present embodiment relates to an electronic apparatus 1 having rolling elements at a first sliding portion and a second sliding portion. Description of parts common to the third embodiment is omitted. FIG. 9 is an explanatory diagram illustrating the configuration of the electronic device 1 according to the fourth embodiment. FIG. 10 is an enlarged view of a portion A in FIG. FIG. 11 is a cross-sectional view of the electronic device 1 taken along line XI-XI in FIG. FIG. 12 is a cross-sectional view of the electronic apparatus 1 taken along line XII-XII in FIG. FIG. 13 is an exploded perspective view of the electronic device 1 according to the fourth embodiment. FIG. 14 is a perspective view of the holding body 72.

  The structure of the 1st sliding part between the 3rd surface 43 of the battery 4 and the bottom face 51 of the battery accommodating part 5 is demonstrated. Two rolling rods 71 are disposed along the longitudinal direction of the battery 4 between the bottom surface 51 of the battery housing 5. The rolling rod 71 is, for example, a piano wire having a diameter of about 0.3 mm to about 0.5 mm. Both ends of the rolling rod 71 are held by holding bodies 72, respectively.

  The holding body 72 has a substantially rectangular plate shape, and has a holding body recess 73 in which one wide surface and an adjacent end surface are cut out. The holding body 72 is fixed to the bottom surface 51 with the wide surface on the holding body recess 73 side facing the bottom surface 51 and the end surface on the holding body recess 73 side facing the battery 4. Both ends of the rolling rod 71 are inserted between the holding body concave portion 73 and the bottom surface 51 so as to be able to roll. The rolling rod 71 and the third surface 43 constitute a first sliding portion.

  The configuration of the second sliding portion between the first surface 41 of the battery 4 and the mover top surface 823 will be described. Two annular plates 75 are fixed to the first surface 41. The annular plate 75 is a flat washer having an outer diameter of 3 mm, an inner diameter of 1.5 mm, and a thickness of about 0.3 mm, for example.

  A rolling ball 76 is disposed between the inside of the annular plate 75 and the moving element top surface 823. The rolling ball 76 is, for example, a steel ball having a diameter of about 0.5 millimeters to about 1 millimeter. The rolling ball 76 is attached to the inside of the annular plate 75 by, for example, grease. The rolling ball 76 and the moving element top surface 823 constitute a second sliding portion.

  The operation of the first sliding part and the second sliding part will be described. When a force in the short direction is applied to the battery 4, the battery 4 moves smoothly as the rolling rod 71 rolls. Even when the end of the rolling rod 71 reaches the edge of the holder recess 73, the side surface of the rolling rod 71 and the third surface 43 of the battery 4 slide, and the rolling rod 71 By rotating, the battery 4 moves smoothly.

The electromagnet 93 is connected to an actuator control board (not shown) via a wiring member 87. Electronic device 1 of the present embodiment does not have the second sliding portion.

  When an operation on the touch panel 2 is accepted or when an incoming call notification is made, current is supplied to the electromagnet 93 via the wiring member 87. The magnetic plate 94 is attracted to the electromagnet 93. The battery 4 moves together with the magnetic plate 94. When the current stops, the battery 4 and the magnetic plate 94 are returned to the original state by the action of the elastic member 95. Note that the elastic member 95 has such an elastic force that the electromagnet 93 and the magnetic plate 94 do not come into contact with each other even when a current is supplied to the electromagnet 93.

  As the battery 4 moves, the entire electronic device 1 shakes. The user of the electronic device 1 feels tactile feedback for the operation of the touch panel 2 and an incoming call notification due to vibration.

  According to the present embodiment, since the electromagnet 93 and the magnetic plate 94 are not in contact with each other, the battery 4 can move smoothly when a longitudinal force is applied.

  Note that the three electromagnets 93 may be connected in series or in parallel. The three electromagnets 93 may have the same magnetic pole directed toward the magnetic plate 94 or different magnetic poles directed toward the magnetic plate 94. One end of the elastic member 95 may be directly fixed to the first surface 41 instead of the magnetic plate 94. The electromagnet 93 and the elastic member 95 may be alternately arranged. Two or four or more electromagnets 93 may be provided. The electromagnet 93 may be fixed to the first surface 41 of the battery 4, and the magnetic plate 94 may be fixed to the inner surface of the battery housing portion 5.
