As illustrated in FIG. 2, the link support plate portion 43 ais formed such that the width W 1 thereof in the front-rear direction is wider than a width W 3 of the driving part support parts 44 in the front-rear direction.As illustrated in FIGS. 1 and 2, the operation force receiving portions 43 bare connection portions at which the lower end portions of the connection plates 42 are rotatably connected by the connection members 42 b. The operation force receiving portions 43 bare arranged so as to be movable up and down in the notch grooves 31 jof the battery stand 31 and outside the lower portions of the left and right side surfaces of the battery case body 2.< Holding Parts>As illustrated in FIG. 2, the driving part support parts 44 are members for restricting the range in which the driving part 43 moves up and down (a height H 1 illustrated in FIGS. 10A and 10B ). The driving part supporting parts 44 are formed of a pair of left and right metal plate members, and each has a guide portion 44 a, notch portions 44 b, a bottom plate portion 44 c, and fastening protrusion parts 44 d. It should be noted that the driving part supporting parts 44 may be omitted.As illustrated in FIGS. 2, 8A, and 8B, the guide portion 44 ais a member for restricting the range of movement of the corresponding operation force receiving portion 43 bof the driving member 43 up and down. The guide portion 44 ais formed in a U-angle shape (substantially the shape of the letter U) in a plan view. As illustrated in FIG. 2, the guide portion 44 ais formed such that the width W 3 of the inner wall of the guide portion 44 ain the front-rear direction is larger than the width W 2 of the operation force receiving portions 43 bin the front-rear direction and is smaller than the width W 1 of the link support plate portion 43 ain the front-rear direction. Thus, the operation force receiving portion 43 bengaged in the guide portion 44 ais engaged so as to be movable up and down between the upper side and the lower side of the guide portion 44 a. In this way, the driving part 43 is restricted in its position change range by the movement up and down.It should be noted that the driving part 43 moves together with the operating part 41 and the link plates 42 of the operating mechanism 4. For this reason, the range of the position change of the driving part 43 by the movement up and down can be defined by restricting the operation of the operating part 41 or the link plates 42.The notch portions 44 bare members for restricting the range of movement of the driving part 43 up and down. As shown in FIGS. 8A and 8B, the guide portion 44 ais notched at the lower front portion and the lower rear portion, forming the notch portions 44 bin an angular U shape (letter U). The left and right end portions of the link support plate portion 43 aare respectively disposed in left notch portions 44 band right notch portions 44 b, and since the width W 3 of the inner wall of the guide portion 44 ain the front-rear direction is smaller than the width W 1 of the link support plate portion 43 ain the front-rear direction as described above, the left and right end portions of the link support plate portion 43 aappear against the upper and lower edges of the notch portions 44 bby the upward and downward movement, thereby allowing the upward and downward movement to be in the range of the position change upward and downward (the height H 1) (see FIG. 2 ).As illustrated in FIG. 2, the bottom plate portion 44 cis a member for reinforcing the guide portion 44 a. The bottom plate portion 44c is formed to form a square bottom plate surface at the lower end portion of the guide portion 44a.The fixing boss portions 44 dare bracket portions for screwing the driving-portion supporting portion 44 to the boss portions 31 hof the battery stand 31 The fixing boss portions 44 dare formed of rectangular portions formed at the front portion and rear portion of the guide portion 44 athat protrude therefrom. The fixing protrusion parts 44 deach have a plurality of screw insertion holes formed therein.< Holder Members>As illustrated in FIG. 7 or 9, the damper support members 45 are members for supporting the dampers 48, and are disposed at the left and right end portions of the link member 49. The damper support members 45 are each configured to have a bottom-side tubular portion 45 a, a flange portion 45 bformed at the edge of the upper opening of the tubular portion 45 a, a bottom portion 45 cof the tubular portion 45 a, and an adjustment screw 5 provided at the bottom portion 45 c.In the tubular portion 45a, a guide portion 47b and the damper 48 are fitted with play. The guide portion 47 bis movable up and down relative to the tubular portion 45 aand the damper 48.The flange portion 45 bis a part for locking the damper support member 45 to an upper surface 49 iof a terminal support portion 49 c. The flange portion 45 bis disposed at the opening edge of an opening 49 dformed in a corresponding one of the left and right portions of the terminal holding portion 49 c.The adjustment screw 5 is a member for adjusting the position of the damper 48 in the up-and-down direction. The adjustment screw 5 is formed of a screw member such as a hexagon socket adjustment screw that is screwed into the female screw portion (not shown) formed on an inner bottom of the damper support member 45 and moves up and down as it rotates.<Elastic Elements>As illustrated in FIGS. 7 and 9, the elastic members SP are members used for the driving part 43 to elastically hold the connecting member 49. The elastic members SP are members that store energy for generating a restoring force in the direction of the position change in response to a position change of the driving part 43, the restoring force being proportional to the position change. The elastic members SP are each formed of, for example, a coil spring. The elastic member SP is fitted around the outer peripheral portion of the tubular portion 45 aof the damper support member 45 in such a manner as to be movable up and down between the bottom surface of the terminal support portion 49 cand a flange portion 46 bof the collar 46.It is to be noted that the elastic members SP do not have coil springs as long as they are elastic, and may be leaf springs, rubber, or the like.<>As illustrated in FIG. 7 or 9, the collars 46 are members for holding the tubular portions 45 aof the damper holding members 45. the collars 46 are a pair of left and right flanged circular tube bodies each having the flange portion 46 bblocked against a corresponding one of the pair of left and right collar attachment holes 43 dand a circular tube portion 46 ainserted into the corresponding collar insertion hole 43 dof the driving part 43.< Element>As shown in FIG. 7, the guide member 47 is a member for guiding raising and lowering of the link 49, and the guide member 47 has a base plate portion 47 a,the guide portions 47 b,stand fixing holes 47 c,the housing-side link insertion hole 47 d,guide portion attachment holes 47 e,and notch grooves 47 f.It should be noted that the outer circumferential shape of the guide member 47 is not limited to a particular shape as long as it serves as a function of guiding the raising and lowering of the link member 49.As shown in FIG. 2, the base plate portion 47 ais fixed to the bottom surface of the outer peripheral portion of the battery side connector engagement hole 31 cof the battery stand 31. The base plate portion 47a is formed of a rectangular flat plate long in the left and right direction along the battery side connector engagement hole 31c.As illustrated in FIG. 7 or 9, the guide portions 47 bprotrude downward from the bottom surfaces of the left and right portions of the base plate portion 47 a. The left and right guide portions 47 bextend from the bottom surface 31 aof the battery stand 31 in parallel to the position change direction of the connection member 49, and the guide portions 47 bare formed of hollow members (tubular members in the present embodiment). Piston rods 48d of the dampers 48 are inserted into the guide portions 47b. The guide portions 47 bare inserted into the tubular portions 45 aof the damper support members 45 so as to be movable up and down. The outer peripheral shape of the guide portions 47 bis similar but smaller than the inner peripheral shape of the damper support members 45, and the inner peripheral shape of the guide portions 47 bis larger than the outer peripheral shape of the dampers 48. when the driving member 43 is at the removed position, at least a part of the total length of each guide portion 47 bis accommodated in the corresponding damper support member 45.The guide portion mounting holes 47 eare formed of circular through holes into which the guide portions 47 bare inserted and mounted. The guide portion mounting holes 47 eare formed in left and right end portions of the base plate portion 47 a.The notch grooves 47 fare provided to weld, at the time of manufacturing the guide member 47, the guide portions 47 b, which are inserted and fitted in the guide portion mounting holes 47 e, to the base plate portion 47 a. The notch grooves 47 fare formed to cut through the base plate portion 47 a, one of which extends from the left edge of the left guide portion attachment hole 47 eto a left end portion of the base plate portion 47 aand the other extends from a right edge of the right guide portion attachment hole 47 eto a right end portion of the base plate portion 47 a. The provision of the notch grooves 47 fallows the size of a region to be welded to be reduced when welding the guide portions 47 binsertion into the guide portion mounting holes 47 e, thus facilitating perpendicularity between the base plate portion 47 aand the guide portions 47 b. Also, welding is performed at positions where spatters are less likely to be generated in the guide portions 47 b, and thus man-hours required for removing the spatter can be reduced.Screw members (not shown) are inserted into the stator fixing holes 47 cto fix the base plate portion 47 ato the battery stator 31 (see FIG. 2 ).The stator mounting holes 47 care formed at left and right end portions of the base plate portion. The guide member 47 is screwed into a bottom surface 31 aof the battery stand 31 as a single removable component. This enables the guide member 47 to have better dimensional accuracy for the left and right guide portions 47 bthereof and to be easily replaced when the guide portions 47 bare worn, as compared with a mode in which the guide portions 47 bare directly welded to the battery stand 31.As shown in FIG. 9, the housing-side connector insertion hole 47 dis a through hole into which the connection terminals 49 a, the guide pins 49 e, and the coupling member 49 bare inserted. As illustrated in FIG. 2, the case-side connector insertion hole 47 dis disposed below and coincides with the battery-side connector engagement hole 31 chaving the same shape.<Connection Element>As illustrated in FIG. 2, the connector 49 is connected to the internal terminals 12 aof the battery 10. As illustrated in FIG. 7, the connecting member 49 includes the connecting terminals 49 a, the terminal support portions 49 b, the terminal support portions 49 c, the openings 49 d, the guide pins 49 e, guide pin support portions 49 f, the coupling member 49 b, and the electric wire connecting portion 49 h.It should be noted that the shape, structure, and the like of the connection member 49 may be changed as needed.The connection terminals 49a are formed by a plurality of external terminals. The upper portions of the connection terminals 49 aprotrude upward from the terminal holding portion 49 c, and the lower ends of the connection terminals 49 aare disposed in the electric wire connection portion 49 h.The terminal supporting portions 49b are protrusions formed at the base end portions of the respective connection terminals 49a to hold the base end portions of the connection terminals 49a. The terminal support portions 49b are formed at appropriate intervals protruding from the top surface of the terminal support portion 49c.As shown in FIG. 7, the terminal holding portion 49 cis a flat plate portion made of a synthetic resin and shaped like a base plate into which the connection terminals 49 aare inserted by injection molding. The terminal holding portion 49 cis elastically held to the driving part 43 with the elastic members SP and the collars 46 interposed therebetween.The openings 49 dare through holes into which the tubular portions 45 aof the damper support members 45 are inserted. The openings 49 dare formed in left and right end portions of the terminal holding portion 49 c. The dampers 48 are inserted into the damper support members 45 inserted into the openings 49d. The damper support members 45 are inserted into the elastic members SP and the collars 46. Thus, the connecting member 49 is elastically held on the driving part 43 by the elastic members SP and also movable up and down via the guide portion 47 b.The guide pins 49 eare members for guiding the movement of the connection terminals 49 a. The guide pins 49 eare formed of rod-shaped members that project upward from positions near the respective left and right end portions of the terminal support portion 49 c. The guide pins 49e are arranged so as to be inserted into the guide pin engaging portions 12b of the battery 10 when the connecting member 49 rises. Thus, the connecting member 49 constitutes an external connecting member.The guide pin holding portions 49f are projections formed at the base end portions of the respective guide pins 49e to hold the base end portions of the respective guide pins 49e. The guide pin holding portions 49f are formed protruding at an appropriate distance from the top of the terminal holding portion 49c.The coupling member 49g is a protrusion for guiding the movement of the connection terminals 49a and engages with the coupling member engagement hole 12c when the connection member 49 is raised. The coupling member 49g is formed as a plate-shaped member that protrudes upward from the terminal holding portion 49c so as to surround the rear side of the connection terminals 49a with an appropriate space therebetween. It is to be noted that the guide pins 49e and the coupling member 49g may be omitted.The electric wire connecting portion 49 his a connecting portion for electrically connecting the connection terminals 49 aconnected to the inner terminals 12 aof the battery 10 to the LED flood light (not illustrated). An electric wire or the like (not shown) extends from the electric wire connecting portion 49 hso as to be connected to the lead wire from the LED flood light (not shown).<>As illustrated in FIG. 2, 7 or 9, the dampers 48 are members held by the connecting member 49. The dampers 48 have a function of reducing the rising speed at which the connecting member 49 is raised by the operation of the operation part 41 (the insertion speed at which the connecting terminals 49 aare inserted into the inner terminals 12 a).The dampers 48 are each configured to include a cylinder 48 c, a piston (not shown), the piston rod 48 d, oil (not shown), and a spring (not shown). Although an example in which the two dampers 48 are arranged on the left and right of the link member 49 is illustrated in FIG. 7, only at least one damper 48 needs to be provided.Also, there are no particular restrictions on the structure and the like of the damper 48 as long as it biases the link member 49 downward. In the following description, a soft absorber (product name) which is a hydraulic damper is used as an example of the damper 48.As illustrated in FIG. 7 or 11A, the damper 48 is inserted into the damper support member 45. An abutting surface 48a located at the lower end of the damper 48 abuts an upper end portion 5a of the adjusting screw 5.As shown in FIG. 11A, a solid cylindrical member is provided at the upper end portion of the damper 48 (the upper end portion of the piston rod 48d). An abutting surface 48b at the lower end of the damper 48 abuts against the bottom surface 31a of the battery stand 31.As illustrated in FIGS. 7 and 11A, the cylinder 48 cis a bottom-side circular tubular outer tube member in which the piston, the oil, and the spring (neither of which is illustrated) are accommodated. The cylinder 48 cis inserted into the tubular portion 45 aof the damper support member 45. The bottom surface of the cylinder 48c abuts an upper end portion 5a of the adjusting screw 5.The piston (not shown) is a cylindrical solid-state member accommodated in the cylinder 48 cin such a manner as to be able to rise and fall. The piston (not shown) is arranged to divide the inside of the cylinder 48 cinto a compression-side pressure chamber and a tension-side pressure chamber, for example. The piston (not shown) is provided with a pressure regulating valve (not shown) for the oil (not shown) to flow between the compression-side pressure chamber and the tension-side pressure chamber. It should be noted that the pressure regulating valve (not shown) may be a clearance provided between the outer circumferential surface of the piston (not shown) and the inner wall of the cylinder 48 cor a small through hole (not shown) provided on the piston.The piston rod 48 dis a rod-shaped member that moves up and down with respect to the cylinder 48 c. The lower end portion of the piston rod 48 dis connected to the piston (not shown).The oil (not shown) is a viscous fluid sealed in the cylinder 48d. The damper 48 is structured such that the linear movement of the piston and the piston rod 48 dis reduced in speed by utilizing a viscosity resistance generated when the oil (not shown) passes through the regulator valve or through an opening having a small flow passage area.The spring (not shown) is a member having a spring force for giving a restoring force to the piston (the piston rod 48d) provided in the cylinder 48c. The spring (not shown) is formed of a compression spring disposed between the inner bottom of the cylinder 48c and the piston (not shown). Thus, the damper 48 generates a resistance force by the combination of a resistance force generated when the piston (not shown) changes its position in the oil and a restoring force of the spring (not shown) expanded and compressed according to the position change of the piston rod 48 d.It should be noted that it is not essential that the damper 48 itself has a function of generating a restoring force. For example, the damper 48 that generates only restoring force due to viscosity resistance in the direction of the position change of the piston may be used, and instead of the spring in the damper 48, an elastic member such as a spring may be provided between the damper support member 45 (a damper abutting member) and the battery stand 31. A pulling force for pulling the connection terminals 49 afrom the inner terminal 12 aof the battery-side connector 12 can also be generated in this manner. Also, the damper 48 that generates only a resistance force due to the viscosity resistance in the direction of the position change of the piston may be used, and the upper and lower ends of the elastic member SP may be fixed to portions where they abut on the connector supporting plate portion 43 aof the driving part 43 and the terminal holding portion 49 cof the connector 49. In this case, as illustrated in FIG. 11E, when the driving part 43 is down, the elastic member SP is expanded to and over the natural length thereof, enabling generation of a pulling force for pulling the connection terminals 49 afrom the inner terminals 12 aof the battery-side connection member 12. Also, regardless of whether an elastic member is provided inside or outside the damper, the elastic member may not necessarily be one that generates the pulling force sufficient to pull the connection terminals 49 aout of the inner terminals 12 aof the battery-side connection member 12. In this case, the connection terminals 49 aare removed from the inner terminals 12 aof the battery-side connector 12 when a user pulls up the battery 10.<<Operation of Connector Driving Structure and Power Source Device Having Same>>Next, with reference to FIGS. 1 to 11F, a description will be given of the operation of the connector driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention.In a case where the power source device 100 illustrated in FIG. 10B is used to supply power from the battery 10 to the LED flood light (not illustrated), first, the operation part 41 is operated rearward to a release position state (the direction of arrow a). Then, as illustrated in FIG. 10A, the handle 41 arotates to be located from a position directly above the battery 10 to a position above and behind the battery 10. The driving part 43 is in communication with the operating part 41 and is therefore lowered by the height H 1. The connector 49, as illustrated in FIG. 11A, descends in conjunction with the descending driving part 43, and the connection terminals 47 amoves away from the inner terminals 12 aof the battery-side connector 12.Next, the grip 13 of the battery 10 is gripped in the release position state in FIG. 10A to pull out the battery 10 from the battery case body 2. The battery 10 thus extracted is charged using a suitable charger.After the battery 10 is completely charged, as shown in FIG. 11A, the battery 10 is slowly inserted into the battery case body 2. It should be noted that, before the battery 10 is inserted, the operation part 41 is brought into the release position state illustrated in FIG. 10A.After the battery 10 is inserted, as illustrated in FIG. 11B, the leg portions 11 abut on the battery stand 31 and are disposed on the battery stand 31. Then, the upper end portions of the guide pins 49e engage with the guide pin engaging portions 12b. The operation part 41 (see FIG. 10A ) is in the release position state here. Thus, the link support plate portion 43 aof the driving part 43 of the operating mechanism 4 abuts against the lower surfaces of the notch portions 44 bat the bottom.Next, the operation part 41 in the released position is operated forward (the direction of arrow b) in FIG. 10A in a fixed position state illustrated in FIG. 10B. Then, as shown in FIG. 11C, the driving part 43 rises together with the operating part 41 and the connection plates 42. It should be noted that the link support plate portion 43 aof the driving part 43 abutting on the lower surfaces of the notch portions 44 bbut now abuts on the upper surfaces of the notch portions 44 b. Due to the rise of the driving part 43, the elastic members SP are compressed between the collars 46 and the terminal holding portion 49c, and thereafter the terminal holding portion 49c is raised by the spring force (restoring force) of the elastic members SP.The terminal support portion 49c thus raised raises the damper support members 45, the dampers 48, and the guide pins 49e. The dampers 48 slow the upward movement of the link member 49 because the rising damper support members 45 push the cylinders 48c upward, lowering the pistons (not shown). Thus, a distance e by which the link member 49 rises becomes smaller than a distance f by which the link plates 42 and the driving part 43 of the operating mechanism 4 rise. Also, the raised terminal holding portion 49c enters the coupling engagement hole 12c. The connection terminals 49 aincreases to positions near the inner terminals 12 aof the battery-side connector 12.As illustrated in FIG. 11D, the elastic members SP compressed by the rising of the driving part 43 lift the connecting member 49 by a distance g due to the restoring force thereof while compressing the dampers 48. Then, the connection terminals 49a are inserted into the inner terminals 12a of the battery side connector 12. As a result, the internal terminals 12 aand the connection terminals 49 aare connected to each other, which allows the battery 10 to supply power to the LED flood light (not shown).It should be noted that the force that raises the connecting member 49 is here (restoring force exerted by two elastic members SP) - (resistance force exerted by the two dampers 48). Thus, in the connector driving structure 1 (the power source device 100), the acting force exerted when the connection terminals 49 aare connected to the inner terminals 12 aby the restoring force of the elastic members SP is reduced by the provision of the dampers 48.In other words, since the connector driving structure 1 has the dampers 48 and the elastic members SP, even if a user operates the operation part 41 too quickly, the connector driving structure 1 reduces the insertion speed at which the connection terminals 49 aare inserted into the inner terminals 12 ato a low speed of a certain value or below. Also, when the connection terminals 49 aare connected to the inner terminals 12 aof the battery-side connector 12, the connector driving structure 1 can also help prevent the connection terminals 49 aand the inner terminals 12 afrom being deformed or damaged due to the effect on connection.In order to charge the battery 10, the operation part 41 is operated rearward (the direction of arrow a) in the fixed state in FIG. 10B to release the state illustrated in FIG. 10A. As a result, the handle 41a of the operating member 41 moves rearward away from the position above the battery 10, thus allowing the battery 10 to be inserted into and removed from the battery case body 2.When the operating part 41 (see FIG. 10A ) is operated and rotated to the released position as illustrated in FIG. 11E, the driving part 43 moves in the direction of arrow h by the height H 1 in conjunction with the operating part 41 and the connection plates 42. By the lowering, the elastic members SP move away from the terminal holding portion 49c and return to their natural length. In this state, the connection terminals 49a are still located in the inner terminals 12a. The guide pins 49e are still located in the guide pin engaging portions 12b.After the elastic members SP move away from the terminal holding portion 49 c, as illustrated in FIG. 11F, the adjustment screws 5 are pressed downward by the restoring force of the springs (not illustrated) provided in the dampers 48. In other words, the damper support members 45 receive a downward force through the dampers 48.When the damper support members 45 thus receive a downward force, the terminal support portion 49 cof the connection member 49 is pressed downward via the flange portion 45 band a force for pulling the connection terminals 49 afrom the inner terminals 12 aof the battery side connection member 12 is generated. Then, the connection terminals 49a are automatically pulled out from the inner terminals 12a by the downward force from the dampers 48, and the state is reset to the state described in FIG. 11B.When a user grasps the grip 13 and pulls up the battery 10 in this state, the battery 10 rises from the battery stand 31 and can be pulled out from the battery case body 2.As thus described, as illustrated in FIG. 2, the battery stand 31 of the connector driving structure 1 according to the present invention has the guide portions 47 bextending in the direction of position change of the connector 49. The guide portions 47 bare hollow members having an outer circumferential shape smaller than the inner circumferential shape of the damper support members 45 and an inner circumferential shape larger than the outer circumferential shape of the dampers 48. When the driving part 43 is in the removed position, at least parts of the total length of the guide portions 47 bare accommodated in the damper support members 45.This configuration allows the guide portions 47 bto guide the movement of the link member 49. Thus, the guide portions 47 bcan smoothly raise and lower the connecting member 49.Since the dampers 48 are accommodated in the guide portions 47 band the damper support members 45 and are not exposed to the outside, damage to the dampers 48 due to contact with the outside and functional failure of the dampers 48 due to accumulation of dust and the like can be prevented.Also, in the link driving structure 1, the guide portions 47 band the dampers 48 are accommodated and coaxially arranged in the damper supporting members 45, the space for mounting the parts can be reduced to make the overall configuration of the link driving structure 1 compact.Also, as shown in FIG. 7, the adjusting screws 5 are screw-fitted into the damper supporting members 45 at the bottom portions 45 cof the damper supporting members 45.According to this configuration, the rotation of the adjusting screws 5 enables fine adjustments to the position of the cylinders 48 cand the distances from the upper end portions 5 aof the adjusting screws 5 to the bottom surface 31 aof the battery stand 31. Also, the adjusting screws 5 can adjust not only a stroke length ST 1 of the dampers 48, but also the clearance between the battery stand 31 and the connection terminals 49 a.Also, as illustrated in FIG. 9, the elastic members SP are coil springs and are provided around the damper support members 45. In other words, the damper support members 45 are provided in the inner spaces of the elastic members SP.This configuration enables effective use of the internal spaces of the elastic members SP and therefore can make the overall configuration of the operating mechanism 4 compact. Also, since the damper support members 45 function as guides when the elastic members SP are expanded and compressed, the elastic members SP do not collapse sideways or are not displaced radially at the time of compression, and are not displaced in position at the time of return to their natural length.Also, as illustrated in FIGS. 1 and 2, the power source device 100 having the connector driving structure 1 is configured to mount the battery 10 to the battery stand 31.This configuration enables seamless connection and disconnection of the connection member 49 to and from the battery 10 mounted in the battery stand 31.[1. Modification]It should be noted that the present invention is not limited to the above-described embodiment and can be variously modified and changed without departing from the technical concept thereof, and needless to say, the present invention includes such modified and changed inventions as well.FIG. 12A is a diagram illustrating a first modification of the connector driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention, and is an enlarged front view of a primary part, which is partially in section, as a connector 49A when the operation part 41 is operated to the released position and the battery 10 is in the battery case body 2.FIG. 12B is a diagram illustrating the first modification of the connector driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention, and is an enlarged front view of a primary part partially illustrating, in section, a state in which the battery 10 is disposed 31 on the battery stand.FIG. 12C is a diagram illustrating a first modification of the connector driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention, and is an enlarged front view of a primary part partially illustrating in section the connector 49A when the operation part 41 is operated to the fixed position.FIG. 12D is a diagram illustrating a first modification of the connector driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention, and is an enlarged front view of a primary part partially illustrating in section how the connector 49A is immediately after the operation part 41 is operated to the fixed position.FIG. 12E is a diagram illustrating the first modification of the connector driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention, and is an enlarged front view of a primary part partially illustrating in section the connector 49A when the operation part 41 is operated to the released position.In the example in the above-described embodiment, each damper 48 is disposed in the damper support member 45 as illustrated in FIGS. 7 and 11A. However, the arrangement of the damper 48 is not limited thereto.As illustrated in FIG. 12A, the damper 48 may be disposed in any manner as long as it can reduce the speed at which the connection ports 49 aare inserted into the internal ports 12 a. For example, the damper 48 may be disposed between the battery stand 31 and the terminal holding portion 49 cof the connector 49A. In other words, one end (the abutting surface 48 a) of each damper 48 may abut on the top surface 49 iof the terminal support portion 49 cfacing the bottom surface 31 aof the battery stand 31, and the other end (the abutting surface 48 b) may abut on the bottom surface 31 aof the battery stand 31.In this case, at least one of the abutting surfaces 48 a, 48 bof the damper 48 may be fixed to the terminal holding portion 49 cor the battery stand 31. This makes it possible to restrain the damper 48 from moving when the operating mechanism 4 is operated.The modes in FIGS. 12A and 12B can omit the damper support members 45 and the collars 49 described in the above embodiment, and thus simplify a link driving structure 1A.Also, the connecting member 49A may be provided with a terminal block 49Aj to adjust the height between the upper surface 49 iof the terminal holding portion 49 cand the connecting terminals 49 a. The terminal block 49Aj is formed of, for example, synthetic resin integrally with the terminal holding portion 49 cand the terminal supporting portions 49 b.This mode also allows the connection terminals 49 ato be connected to the inner terminals 12 aof the battery-side connector 12 before the damper 48 changes its position to the lower limit value of the stroke length ST 1 (i.e., becomes shortest).Also, as described in the example in the above embodiment, the elastic member SP is provided around the damper support member 45 as illustrated in FIGS. 7 and 11A, but the present invention is not limited to such a mode. The elastic member SP may be easily disposed between the terminal holding portion 49 cand a connector supporting plate portion 43Aa of a driving part 43A, as shown in FIG. 12A. This configuration also constitutes the connecting member 49a which is elastically supported by the driving part 43A.This can eliminate the need for the collar 46 and the damper support member 45, which support the elastic member SP and simplify the structure because they are fewer parts.Also, in the connector support plate portion 43Aa of the driving part 43A, only the electric wire connection portion disposing hole 43 cis formed, and the coil mounting hole 43 d(see FIG. 7 ) described in the embodiment is not formed. It should be noted that the electric wire connecting portion disposing opening 43 cmay be a notch.Next, with reference to FIGS. 12A to 12E, the operation of the connector driving structure 1A and a power source device 100A having the like will be described.As illustrated in FIG. 12A, in order for the power source device 100A to be able to supply power to the LED flood light (not illustrated), first, the operation part 41 (see FIG. 1 ) is operated to the release position state, and the charged battery 10 is inserted into the battery case body 2.Then, the battery 10 is lowered until the leg portions 11 abut on the battery stand 31, and thereby is disposed on the battery stand 31, as shown in FIG. 12B. In this case, in the operation mechanism 4, since the operation part 41 (see FIG. 1 ) is in the release position state, the link support plate portion 43Aa of the drive part 43A is lowered while abutting on the lower surfaces of the notch portions 44 b.Next, the fastening member 41 (see FIG. 1 ) is operated to the fixed position state in the release position state. Then, as illustrated in FIG. 12C, the link plates 42 and the driving part 43A rise to positions where the link support plate portion 43Aaa of the driving part 43A abutting the lower surfaces of the notch portions 44 bbut abuts the upper surfaces of the notch portions 44 b. When the driving part 43A rises, the elastic member SP is compressed between the link support plate portion 43Aa and the terminal support portion 49 c, and thereafter the terminal support portion 49 cis raised by the spring force (restoring force) of the elastic member SP.The raised terminal holding portion 49 clifts the damper 48 and the connecting member 49A. The piston (not shown) in the damper 48 is lowered as the cylinder 48 cis pushed up by the rising port support portion 49 c, and thus the damper 48 can slow the rising movement of the link member 49A.As illustrated in FIG. 12D, the elastic member SP compressed by the rise of the driving part 43A further raises the connecting member 49A while compressing the damper 48 with the restoring force. Then, the connection terminals 49a are inserted into the inner terminals 12a of the battery side connection member 12 before the elastic member SP fully expands to its natural length and the damper 48 is fully compressed (it is to be noted that in order to meet this requirement, the length of the connection member 49A and the stroke length ST1 of the damper 48 must be set accordingly). As a result, the connection terminals 49 aand the internal terminals 12 aare connected to each other, which allows the battery 10 to supply power to the LED flood light (not shown).When the lengths of the portions are set so that the connection terminals 49 aand the inner terminals 12 acan be coupled to each other before the elastic member SP is fully expanded, the spring force of the elastic member SP can exert a suitable force to maintain the coupling with the connection member 49A even after the coupling.In the connector driving structure 1A (the power source device 100A), the provision of the damper 48 can reduce the insertion speed at which the connection terminals 49 aare connected to the inner terminals 12 athrough the elastic member SP, thereby reducing an impact force and a drastic change in position.Also, when the operation part 41 (see FIG. 1 ) is operated to the released position together with the rotating operation part 41 (see FIG. 1 ), the drive part 43A is lowered by the height H 1 via the connection plates 42 as illustrated in FIG. 12E. When the driving part 43A is lowered, the elastic member SP moves away from the terminal holding portion 49 cand returns to its natural length. In this case, the connecting terminals 49a are still in the inner terminals 12a, and the guide pins 49e are also in the guide pin engaging portions 12b.After the elastic member SP moves away from the terminal holding portion 49 c, the damper 48 presses down the terminal holding portion 49 c, which is located at the lower end of the damper 48, due to the restoring force of the spring (not illustrated) provided in the damper 48, thereby pulling out the connection terminals 49 afrom the inner terminals 12 a. Thus, the connection ports 49 aare automatically taken out from the inner ports 12 aby the downward force exerted by the damper 48, and the state is restored to the state described above in FIG. 12B.In this way, the connector driving structure 1A can achieve operations and advantageous effects similar to those provided by the embodiment even when the damper 48 is disposed between the battery stand 31 and the terminal support portion 49 cand the elastic member SP is disposed between the terminal support portion 49 cand the connector support plate portion 43Aa.As illustrated in FIG. 12A, the first modification of the terminal driving structure 1 includes the operation part 41, the driving part 43A that moves together with the movement of the operation part 41, the connection member 49A that is elastically supported by the driving force 43A via at least one elastic member SP, at least one damper 48 that is supported by the connection member 49A, and the battery stand 31. By the operation of the operation part 41, the driving part 43A changes the position between the near position near the battery stand 31 and the far position away from the battery stand 31. The connection member 49A includes connection terminals 49 aand the terminal holding portion 49 cthat holds the connection terminals 49 a. One end (the abutting surface 48 a) of the damper 48 is supported by the terminal support portion 49 c, while the other end (the abutting surface 48 b) of the damper 48 abuts on the bottom surface 31 aof the battery stand 31.This configuration causes the connecting member 49A not to immediately respond to the operation of the operation part 41 (see FIG. 1 ). In other words, sudden lifting of the connecting member 49A held on the driving part 43A with the elastic member SP interposed therebetween can be restricted by the resistance force of the damper 48 provided between the connecting member 49A and the battery stand 31. Due to the restoring force of the elastic member SP that has absorbed the upward positional change of the driving part 43A, the connecting member 49A rises while counteracting the resistance force of the damper 48. Thus, the rising speed of the connecting member 49A can be reduced.In this way, the link driving structure 1A can make constant the speed at which the link 49A changes position regardless of the speed at which the operation part 41 is operated. Thus, even if the operation part 41 is operated too quickly, the speed at which the link member 49A changes position can be made to be a predetermined speed or lower.[2. Modification]FIG. 13A is a diagram illustrating a second modification of the connector driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention, and is an enlarged front view of a primary part partially illustrating in section how the damper 48 is installed.FIG. 13B is a diagram illustrating the second modification of the connector drive structure 1 and the power source device 100 including the same according to the embodiment of the present invention, and is an enlarged side view of a primary part showing how the damper 48 is installed.In the example illustrated in FIG. 11A, the damper 48 has the upper end side thereof inserted into the guide portion 47 band the lower end side inserted into the collar 46 and the opening 49 din the terminal holding portion 49 c, but the present invention is not limited to such a configuration.As illustrated in FIGS. 13A and 13B, the damper 48 only needs to be disposed between the battery stand 31 and a terminal support portion 49C. In this case, the damper 48 may be disposed at a position offset from a driving part 43 bin the front and rear direction, for example, so as not to pass through the driving part 43B.Also, the driving part 43B may be provided with an elastic member holding portion 43Ba that holds the elastic member SP. The elastic member holding portion 43Ba includes a receiving portion 43B that receives the elastic member SP from below and a holding portion 43C that is provided upright at a center portion of the upper surface of the receiving portion 43B. The support portion 43B passes through an insertion hole 49C 1 of the terminal support portion 49C, and the upper end of the support portion 43B is fixed to the connector support plate portion 43 a.According to a link driving structure 1B of the second modification, the elastic member SP is expanded and compressed while being guided by the elastic member supporting portion 43Ba, and thus can be prevented from being displaced.[3. Modification]FIG. 14 is a diagram illustrating a third modification of the connector drive structure 1 and the power source device 100 including the same according to the embodiment of the present invention, and is an enlarged side view of the primary part illustrating how the damper 48 is installed.In the second modification illustrated in FIG. 13B, the damper 48 is disposed away from the driving part 43B and does not pass through the driving part 43B, but the damper 48 may be disposed differently.As illustrated in FIG. 14, the damper 48 may be disposed to pass through a through hole 43Ca 1 that passes through the link support plate portion 43 aof a driving part 43C so as to be movable up and down.Specifically, the damper 48 is inserted through the through holes 43Ca 1, and the abutting surface 48 aat the lower end of the damper 48 is disposed on the terminal holding portion 49Cc, and the abutting surface 48 bat the upper end of the damper 48 is fixed to the bottom surface 31 aof the battery stand 31. The damper 48 is disposed on the axis of the support portion 43C of the driving part 43C in a side view.According to a link driving structure 1C of the third modification, the damper 48, the driving part 43C, and a link 49C can be arranged in a compact manner, realizing a reduction in size.[4. Modification]FIG. 15 is a diagram illustrating a fourth modification of the connector driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention, and is an enlarged front view of a primary part partially illustrating in section how the damper 48 is installed.As illustrated in FIG. 15, the damper 48 may be fixed to at least one of the terminal holding portion 49 cand the battery stand 31.Specifically, in the fourth modification, the damper 48 is disposed such that one end thereof abuts on the terminal support portion 49 c. The damper 48 may have the abutment surface 48 aat the lower end thereof fixed to the terminal support portion 49 cor have the abutment surfaces 48 bat the upper end thereof fixed to the battery stand 31.According to this configuration, members for holding the damper 48 are omitted, which allows a reduction in the number of parts. Thus, a link driving structure 1D of the fourth modification can have a simple slender structure.Also, since at least one of the abutting surface 48 aon the terminal support portion 49 cside and the abutting surfaces 48 bon the battery stand 31 side of the damper 48 is fixed, a simple fixing structure can be obtained.[5. Modification]FIG. 16A is a diagram illustrating a fifth modification of the connector driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention, and is an enlarged front view of a primary part partially illustrating in section how a damper support member 45E is installed.FIG. 16B is a diagram illustrating the fifth modification of the connector driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention, and is an enlarged side view of a primary part showing how the damper support member 45E is installed.FIG. 16C shows the fifth modification of the link driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention, and is an enlarged perspective view of the damper support member 45E.As shown in FIGS. 16A to 16C, a damper 48E is supported by the bottom-side damper support tubular member 45E. One end (the abutting surface 48 aat the lower end) of the damper 48E abuts on the bottom portion 45Ec of the damper support member 45E, and at least a part of the entire length of the damper 48E is accommodated in the damper support member 45E.The damper support member 45E is, as shown in FIG. 16C, formed as a tubular body having a tube portion 45Ea having the bottom portion 45Ec and a flange portion 45Ea at the upper end portion of the tube portion 45Ea. The flange portion 45Eb is locked to the upper opening edge of the opening 49 din the terminal holding portion 49 c. As illustrated in FIGS. 16A and 16B, the damper support member 45E extends downward from the terminal support portion 49 c, which allows a space for mounting the damper 48E not to be restricted from the distance by which the battery stand 31 and the lead portion 49 care spaced apart from each other. In other words, the length of the damper 48E in the up-and-down direction can be made an appropriate length.It should be noted that, according to the raising and lowering of the connecting member 49A, the damper 48E rises and lowers together with the damper supporting member 45E.According to this configuration, in which at least a part of the total length of the damper 48E is accommodated in the damper support member 45E, the damper 48E can be used with an appropriate length. Also, since there is no adjustment screw (see FIG. 7 ) at the bottom portion 45Ec of the damper support member 45E, the number of parts can be reduced.[6. Modification]FIGS. 17A to 17C are diagrams illustrating a sixth modification of the link driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention, FIG. 17A is an enlarged plan view of a link member 49F, FIG. 17B is an enlarged plan view of the link member 49F, FIG. 17C is an enlarged perspective view of a damper support member 45F.Although the damper support member 45E of the above-described fifth modification has the flange portion 45Ea, the flange portion 45Ea may be omitted to give the damper support member 45E a bottom-side circular tubular shape like the damper support member 45F illustrated in FIGS. 17A to 17C.The damper support member 45F is either inserted and fixed into the opening 49 din a terminal support portion 49Fc of the connection member 49F, or formed integrally with the terminal support portion 49Fc.This can simplify the shape of the damper support member 45F. Also, forming the damper support member 45F integrally with the connection member 49F enables a reduction in the number of parts.[7. Modification]FIG. 18 shows a seventh modification of the link driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention, and is an enlarged perspective view of a damper support member 45G.The damper support member 45F in the sixth modification described above may have a bottom-side square tubular shape, like the damper support member 45G illustrated in FIG. 18.The damper support member 45G has either the upper end portion thereof inserted and fitted into the circular or square hole 49 dformed in the terminal support portion 49 cof the connection member 49, or is integrally formed with the terminal support portion 49 c(see FIGS. 17A and 17B ).The damper support member 45G can thus have a simple shape.[8. Modification]FIGS. 19A and 19B are diagrams illustrating an eighth modification of the link driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention, FIG. 19A is an enlarged perspective view of a damper support member 45H having a bottom-side circular tubular shape, FIG. 19B is an enlarged perspective view of a damper support member 45I having a bottom-side square tubular shape.The damper support member 45 in the above embodiment is not limited to a pipe member having a flange portion 45 bas illustrated in FIG. 7.As illustrated in FIG. 19A, the damper support member 45H having the adjustment screw 5 may be configured as a bottom-side circular tube shape without the flange portion 45 b(see FIG. 7 ) as in the sixth modification (see FIG. 17C ). Also, as illustrated in FIG. 19B, the damper support member 45I including the adjustment screw 5 may be formed of a bottom-side square tubular shape without the flange portion 45 b(see FIG. 7 ) as in the seventh modification (see FIG. 18 ).In this case, the damper support member 45H, 45I is integrally formed by, for example, inserting and fitting the upper end portion into the opening 49 dformed in the terminal support portion 49 cof the connection member 49, or by being integrally formed with the terminal support portion 49 c(see FIGS. 17A and 17B ).A link driving structure 1H, 1I of the eighth modification of the present invention can thus simplify the shape of the damper support member 45H, 4 5 I. Also, the integral formation of the damper support member 45H, 45I with the connection member 49 (see FIG. 9 ) can reduce the number of parts.[9. Modification]FIG. 20A is an enlarged front view of a primary part partially illustrating, in section, how a driving part 43J of a ninth modification of the connector driving structure 1 and the power source device 100 is incorporated therewith according to the embodiment of the present invention.FIG. 20B is an enlarged perspective view of a primary part partially illustrating, in section, how a driving part 43J of the ninth modification of the connector driving structure 1 and the power source device 100 is incorporated therewith according to the embodiment of the present invention.FIG. 20C is an enlarged front view of a primary part partially illustrating, in section, a modification of the ninth modification of the connector driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention.As illustrated in FIG. 20A, FIG. 20B, or FIG. 20C, the damper support member 45 may extend downward from the driving part 43J, 43K via an opening 43Ea or a notch portion 43Ke formed in the driving part 43J, 43K.In this case, the driving part 43J illustrated in FIGS. 20A and 20B includes a link support plate portion 43Ja and operation force receiving plate portions 43Jb. The connector support plate portion 43Ja has an opening 43Jc for disposing a connecting portion of the electric wire and the opening 43Je formed therein. The electric wire connecting portion 49 his inserted into the electric wire connecting portion disposing opening 43Jc so as to be movable up and down. The opening 43Aa is formed of a circular through hole formed in a central portion in the front and rear direction of the connector support plate portion 43Aa. The tubular portion 45A of the damper support member 45 is inserted into the opening 43Aa so as to be movable up and down. The opening 43Aa is formed on the axis of the opening 49 din the terminal holding portion 49 cand is configured in size to be capable of guiding the movement of the tubular portion 45 aup and down.Also, the opening 43Ea of the driving part 43J only needs to be capable of guiding the upward and downward movement of the damper support members 45. Thus, as illustrated in FIG. 20C, the opening 43Je may be the notch portion 43Ke formed in a link support plate portion 43Ka of the driving part 43K.The notch portion 43Ke is formed of a semicircular notch groove formed in an edge portion (for example, a rear edge portion) in the front and rear direction of the connector support plate portion 43Ka. The notch portion 43Ke is formed on the axis of the opening 49Ea in a terminal holding portion 49K and is configured in size to be capable of guiding the movement of the tubular portion 45 aup and down. Thus, the width in the front-rear direction of the terminal support portion 49K is larger than the width in the front-rear direction of the terminal support portion 49 cillustrated in FIG. 20B because the notch portion 43Ke illustrated in FIG. 20C is formed at a position near the rear edge portion of the connector support plate portion 43Ka. Also, the axis of the damper support member 45 and the damper 48 are arranged offset in the up-and-down direction at a position from a center line of a link member 49K in a side view.As illustrated in FIGS. 20A to 20C, the driving part 43J, 43K may have either one of the opening 43Ea and the notch portion 43Ke as long as the damper support member 45 is arranged to be movable up and down and to be guided for its movement up and down by the driving part 43J, 43K. Also, the shape of the opening 43Ea or the notch portion 43Ke is not limited to a circle or a semicircle, and may be appropriately selected to match the outer circumferential shape of the damper support member 45.When the opening 43Ea or the notch portion 43Ke is thus formed in the driving part 43J, 43K, the driving part 43J, 43K can be disposed near the battery stand 31 while creating sufficient space for installing the damper 48. Thus, the overall configuration of a link driving structure 1K, 1J can be made compact. Also, in the link driving structure 1K, 1J, the opening 43Ea or the notch portion 43Ke serves as a guide for the link 49, 49K, and therefore can reduce the displacement of the link 49, 49K.[10. Modification]FIG. 21A is an enlarged front view of a primary part partially illustrating, in section, how the collar 46 of a tenth modification of the connector driving structure 1 and the power source device 100 is incorporated therewith according to the embodiment of the present invention.FIG. 21B is an enlarged perspective view of a primary part illustrating how the collar 46 of the tenth modification of the connector driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention is installed. FIG. 21C is an enlarged perspective view of a primary part illustrating a modification of the tenth modification of the connector driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention.As shown in FIGS. 21A to 21C, the collar 46, 46M made of synthetic resin may be provided in the opening 43Ea or the notch portion 43Ke of the ninth modification shown in FIGS. 20A to 20C.As illustrated in FIGS. 21A and 21B, the opening 43Aa in the driving part 43J is formed on the axis of the opening 49 din the terminal holding portion 49 c. The collar 46 in a flanged circular tube shape is provided at the opening 43Aa. The collar 46 includes the circular tube portions 46a and the flange portion 46b. The flange portion 46b is formed at the edge portion of the mouth of the opening 43Aa.Also, as illustrated in FIG. 21C, the notch portion 43Ke in the driving part 43K is formed on the axis of the opening 49Ea in the terminal holding portion 49C. The collar 46M of a semicircular tubular shape is provided at the notch portion 43Ke. The collar 46M has a semicircular tube portion 46Ma and a semi-annular flange portion 46Mb.According to the link driving structure 1L, 1M in which the collar 46, 46M made of resin is provided in the opening 43Ea or the notch portion 43Ke in the driving part 43J, 43K, the damper support member 45 can slide smoothly. Also, when members wear after repeated use of the terminal driving structure 1L, 1M, this can be released by replacement of only the collar 46, 46M, enabling a reduction in maintenance costs for the operating mechanism 4. Also, forming the collar 46, 46M from resin can reduce the cost and weight of the part. It should be noted that the inner and outer circumferential shapes of the collars 46, 46M are not limited to a circle or a semicircle, and may be selected appropriately to match the outer circumferential shape of the damper support member 45 and the shape of the opening 43Ea or the notch portion 43Ke.[11. Modification]FIG. 22A is an enlarged sectional view of a primary part illustrating how a guide 34 for raising and lowering an eleventh modification of the connector driving structure 1 and the power source device 100 is incorporated therewith according to the embodiment of the present invention.FIG. 22B is an enlarged perspective view of a primary part, partially in section, illustrating how a guide 34 for raising and lowering an eleventh modification of the link driving structure 1 and the power source device 100 is incorporated therewith according to the embodiment of the present invention.As illustrated in FIGS. 22A and 22B, the battery stand 31 may be provided with the raising and lowering guide 34 that extends in a direction parallel to the direction in which the link member 49 changes position. The raising and lowering guide 34 is inserted through, for example, a guide insertion hole 49K formed in the terminal holding portion 49 c.The raising and lowering guide 34 is a member for raising and lowering a link member 49P and a driving part 43P without moving them sideways. The raising and lowering guide 34 is formed of a member extending from the bottom surface 31 aof the battery stand 31 in the direction of change in position of the connection member (downward). The upper end of the raising and lowering guide 34 is fixed to the bottom surface 31a of the battery supporting body 3. The guide insertion hole 49K is formed in a terminal holding portion 49Pc, and a guide insertion hole 43Pe is formed in the connector supporting plate portion 43a. The raising and lowering guide 34 is formed by the guide insertion hole 49K and the guide insertion hole 43Pe. The shape of the outer circumferential surface of the raising and lowering guide 34 may be any shape as long as the raising and lowering guide 34 can serve as a guide, and the raising and lowering guide 34 may be formed as one that is circular in a cross-sectional view, for example, such as the guide insertion hole 49K and the guide insertion hole 43Pe. The guide insertion hole 49K and the guide insertion hole 43Pe are also not limited to have a circular shape as long as they can guide the guide 34 for raising and lowering.It should be noted that the raising and lowering guide 34 needs only one raising and lowering guide of at least the link member 49P, and may be configured not to guide the driving part 43P by omitting the guide insertion hole 43Pe in the driving part 43P. Also, the sectional shape and thickness of the raising and lowering guide 34 are not limited to particular ones, and may be other shapes such as a polygon.With the raising and lowering guide 34, the battery stand 31 allows the connecting member 49P to stably rise and fall. Since the guide 34 for raising and lowering is inserted through the guide insertion hole 49K into the terminal holding portion 49 c, the connection terminals 49 aof the connection member 49P are less likely to be laterally displaced.[12. Modification]FIG. 23A is an enlarged front view of a primary part partially illustrating, in section, a twelfth modification of the connector driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention.FIG. 23B is an enlarged side view of a primary part illustrating a twelfth modification of the connector driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention.As illustrated in FIGS. 23A and 23B, the damper support member 45 and the driving part 43 may be disposed offset from each other in the front-rear direction so as not to interfere with each other.An opening 49Qd formed in the terminal holding portion 49Qc of a link member 49Q is disposed away rearward from the driving part 43. This configuration also allows damper support members 45Q to move up and down integrally with the link member 49Q.A thus configured connector driving structure 1Q of the twelfth modification can function as described in the embodiment above.[13. Modification]FIGS. 24A and 24B are diagrams illustrating a thirteenth modification of the link driving structure 1 and the power source device 100 including the same according to the embodiment of the present invention, FIG. 24A is a side view illustrating how an operation mechanism 4R is operated when an operation part 41R is operated to the released position (downward), FIG. 24B is a side view illustrating the operation mechanism 4R when the operation part 41R is operated to the fixed position (upward).As illustrated in FIGS. 24A and 24B, the operation mechanism 4R may be of an upward drawing type such that the operation part 41R is operated by upward drawing.The operation mechanism 4R is configured to include the operation part 41R that is operated by being first pulled up or pushed down, connection plates 42R that move up and down integrally with the operation part 41R, and a drive part 43R that moves up and down integrally with the operation part 41R. It is to be noted that the operation part 41R, the connection plates 42R, and the drive part 43R may be made of a single integrally formed member.The operating mechanism 4R is thus configured to operate the same as the operating mechanism 4 of the embodiment. Also, when the operation part 41R, the connection plates 42R, and the drive part 43R are formed as a single member, the operation mechanism 4R requires fewer parts and fewer man-hours for assembly.[14. Modification]FIGS. 25A and 25B are diagrams illustrating a fourteenth modification of the link driving structure 1 and the power source device 100 including the same according to an embodiment of the present invention, FIG. 25A is a side view illustrating a state in which an actuator 42S is operated to the released position (downward), FIG. 25B is a side view illustrating a state in which the actuator 42S is operated to a fixed position (upward).As illustrated in FIGS. 25A and 25B, the operation mechanism 4S may be a switch operation type such that a driving part 43S moves up and down when the actuator 42S is driven.The operation mechanism 4S is configured including an operation panel 41S configured of a switch, the actuator 42S that is driven when the operation panel 41S is operated, and the drive part 43S is moved up and down by the actuator 42S.The operation panel 41S may be a switch that sends a drive signal to drive the actuator 42S. The operation panel 41S is formed of a switch such as a push switch, a lever switch, or a slide switch.The actuator 42S is formed of, for example, a solenoid or a motor-driven device, and raises or lowers the drive part 43S at an appropriate speed when driven.The operating mechanism 4S thus configured can operate as well as the operating mechanism 4 of the embodiment. By using the electrically operated actuator 42S, the operating mechanism 4S can form a link driving structure without using a link structure.[Other Modifications]As illustrated in FIGS. 1 and 2, the connecting member 49 described in the embodiment is held on the driving part 43 such that the elastic members SP are compressed when the driving part 43 changes the position upward. However, the present invention is not limited thereto. The driving part 43 can be held in a manner such that the elastic members SP are expanded when the driving part 43 changes the position upward. This case causes no problem in the functionality because the elastic members SP generate a restoring force in proportion to the change in position of the driving part 43.Also, although separately formed in the example described in the embodiment, the battery case body 2 and the battery holder body 3 may be integrally formed as a single member. In other words, the vertical frames 32 and the upper frame 33 of the battery supporting body 3 may be omitted.In this case, the battery stand 31 is provided at the bottom portion of the battery case body 2 to form the battery case body 2 as a bottom-side square tube body. Then, the operation member 41 of the rotating type can be pivotally supported on the side surfaces of the upper portion of the battery case body 2 in a manner that the operation member 41 can be operated and rotated.Also, depending on the shape of the operation part 41, the notch grooves 31 jmay be formed in the left and right side surfaces of the battery case body 2 as needed to allow the operation mechanism 4 to move up and down.
