Stopped.
In addition, the side edge nail | claw part 52 is divided in the back surface 33a side of the battery cover 33 ahead of the position which divides the battery cover 33 into 2 length directions (in this example, the battery cover 33 is divided into 3 length directions). In front of the position).

Here, the dimensions of the respective portions of the side end locking portion 44 and the side end claw portion 52 are set so that the battery cover 33 can be smoothly attached and removed by the sliding operation of the battery cover 33 and is appropriate at the time of attachment. It is adjusted in advance and set in an optimum range so that a stable engagement state can be stably maintained and securely attached.
In this example, the lower surface 64a and the bottom surface 63p are formed, for example, so as to be parallel to the bottom surface 34a of the recess 34, and the upper surface 52q and the lower surface 52r are, for example, relative to the back surface 33a and the outer surface 33b of the battery cover 33. Are formed to be parallel to each other.

For this reason, setting and adjustment of the dimensions of the respective portions of the side end locking portion 44 and the side end claw portion 52 are performed when, for example, an axis along the slide direction is selected as the reference axis (for example, the x axis), It is possible to independently execute a dimension along the slide direction (x-axis coordinate) and a dimension along the direction orthogonal to the slide direction (for example, the thickness direction of the battery cover 33) (z-axis coordinate). It has become.
For example, the lower surface 64a as the locking surface and the upper surface 52q as the locked surface are brought into contact with each other against each other against the force to be separated, and the tip portion of the hook portion 52b is stored. In particular, the dimension in the z-axis direction of the hook part 52b and the storage part 63a has an allowable specified minimum value and a specified maximum value depending on the required accuracy so that the part 63a can be smoothly inserted and removed. Is set.

When the battery cover 33 is placed on the placement portion 42 so that the side end claw portion 52 is inserted into the clearance portion 63b, the hook portion 52b is located below the protrusion 64 when the battery cover 33 is slid forward. The side end claw portion 52 is displaced so as to sink into the storage portion 63 a, and the side end claw portion 52 is locked by the side end locking portion 44.
Here, the contact between the lower surface 64a of the protrusion 64 and the upper surface 52q of the hook portion 52b prevents the upward displacement of the battery cover 33 against the force to lift the battery cover 33.

Further, the battery cover 33 is displaced forward by contact between the rear end surface 64b of the protrusion 64 and the front end surface 52p of the hanging portion 52a, and contact between the inner wall surface 63q of the recess 63 and the front end surface 52s of the hook portion 52b. Stopped.
When the battery cover 33 is slid rearward and the hook portion 52b moves to the clearance portion 63b and is disengaged from the projection portion 64, the side end claw portion 52 is locked by the side end locking portion 44. (The engagement relationship between the side locking portion 44 and the side claw portion 52 is released).

As shown in FIG. 5, the rear end locking portion 45 is a cross section in which the rear end claw portion 53 is accommodated so as to be displaceable within a predetermined range along the length direction (sliding direction) of the rear case 32. A substantially rectangular concave portion 66 and a lid portion 68 that closes a part of the concave portion 66 leaving a rectangular opening 67 for inserting the rear end claw portion 53 formed on the rear end side are provided.
The edge portion on the front end side of the opening 67 of the lid portion 68 faces or abuts against the inclined surface 53p of the rear end claw portion 53, for example, against the bottom surface 34a of the concave portion 34 (with respect to the length direction of the rear case 32). Thus, an inclined surface 68a inclined at a predetermined inclination angle is formed. The recess 66 has a bottom surface 66 a that faces the lower surface 53 q of the rear end claw portion 53.

The rear end claw portion 53 has a hook portion 53a that hangs down from the back surface 33a of the battery cover 33. The hook portion 53a faces or abuts against the inclined surface 68a of the lid portion 68, and against the back surface 33a and the outer surface 33b. It has an inclined surface 53p inclined at a predetermined inclination angle (with respect to the length direction of the battery cover 33) and a lower surface 53q facing the bottom surface 66a.
The inclination angle of the inclined surface 53p and the inclination angle of the inclined surface 68p are set to be substantially the same when the rear end claw portion 53 is locked by the rear end locking portion 45.
Here, the dimensions of each part of the rear end locking portion 45 and the rear end claw portion 53 are set so that the battery cover 33 can be smoothly attached and removed by the sliding operation of the battery cover 33, and is appropriate at the time of attachment. It is adjusted in advance and set in an optimum range so that a stable engagement state can be stably maintained and securely attached.

When the battery cover 33 is slid forward in a state where the battery cover 33 is mounted on the mounting portion so that the rear end claw portion 53 is inserted into the recess 66 from the opening 67, the inclined surface is inclined with respect to the inclined surface 68a. The side end claw portion 52 is displaced so that the rear end claw portion 53 sinks below the lid portion 68 while the 53p slides, and the rear end claw portion 53 is locked by the rear end locking portion 45.
Here, due to the contact between the inclined surface 68a and the inclined surface 53p, the upward displacement of the battery cover 33 is restrained against the force of lifting the battery cover 33, and the battery cover 33 is moved forward. Displacement is restrained.
When the battery cover 33 is slid rearward, the rear end claw portion 53 moves to the concave portion 66 immediately below the opening 67 and is detached from the lid portion 68, so that the rear end claw portion 53 is engaged by the rear end locking portion 45. The stopped locking state is released (the engagement relationship between the rear end locking portion 45 and the rear end claw portion 53 is released).

Next, the reason why the locking surface and the locked surface of the rear end locking portion and the rear end claw portion of the mobile phone 1 of this example are in contact with each other will be described with reference to FIGS. 7 to 9. .
FIG. 7 shows a sliding direction of the locking surface and the locked surface of the side end locking portion and the side end claw portion, and the locking surface and the locked surface of the rear end locking portion and the rear end claw portion. Sectional drawing of the foldable mobile telephone when it is made parallel along (it is substantially parallel to the attached battery cover) is shown.

  In this cellular phone 1A, as shown in FIG. 7 and FIG. 8, the battery cover mounting structure 71 has a battery cover 72 in a state where the peripheral portion of the back surface 72a is placed on the placement portion 74 of the rear case 73. The mounting portion 74 is slid along the length of the rear case 73 from the side where the hinge portion 75 is formed toward the tip portion, and a front end claw portion 76 and a pair of left and right side end claw portions 77 The rear end claw portion 78 is locked by a front end locking portion 79 formed on the mounting portion 74, a pair of left and right side locking portions 81, and a rear end locking portion 82. Thus, the rear case 73 is detachably attached and is schematically configured.

The front end claw portion 76 and the front end locking portion 79 have substantially the same configuration as the front end claw portion 51 and the front end locking portion 43 of the mobile phone 1.
The side end claw portion 77 and the side portion locking portion 81 have substantially the same configuration as the side end claw portion 52 and the side portion locking portion 44 of the mobile phone 1.
That is, as shown in FIGS. 7 and 8, the side end locking portion 81 is such that the side end claw portion 77 can be displaced within a predetermined range along the length direction (sliding direction) of the rear case 73. And a substantially rectangular parallelepiped protrusion 84 projecting from the side wall surface of the corner on the front side of the recess 83 (the front end side of the rear case 73).
The protrusion 84 has a lower surface 84a on which the upper surface 77q of the hook portion 77b of the side end claw portion 77 abuts, and a front end surface 77p of the hanging portion 77a of the side end claw portion 77 perpendicular to the lower surface 84a. And an end face 84b. For example, the lower surface 84a is formed to be parallel to the bottom surface of the concave portion of the battery storage unit.

The recess 83 is formed immediately below the lower surface 84a of the projection 84, and a clearance 83 that allows displacement of the side end claw 77 within a predetermined range of the storage 83a in which the hook 77b of the side end claw 77 is stored. Part (margin part) 83b.
In addition, the recess 83 faces the bottom surface 83p where the lower surface 77r of the hook portion 77b of the side end claw portion 77 faces or slides, and the front end surface 77s of the hook portion 77b of the side end claw portion 77 which is perpendicular to the bottom surface 83p. An inner wall surface 83q. The bottom surface 83p is formed, for example, so as to be parallel to the bottom surface of the recess of the battery storage unit.

The side end claw portion 77 is formed in a bowl shape having a substantially L-shaped cross section, and a hanging portion 77a hanging from the back surface 72a side of the battery cover 72, and a hook portion 77b supported by the hanging portion 77a and projecting forward. And have.
The hanging portion 77a has a front end surface 77p with which the rear end surface 84b of the protruding portion 84 abuts. The hook portion 77b faces the upper surface 77q that the lower surface 84a of the projection 84 faces, the lower surface 77r that faces or slides against the bottom surface 83p of the recess 83, and the inner wall surface 83q of the recess 83 that is perpendicular to the lower surface 77r. And a front end face 77s. The upper surface 77q and the lower surface 77r are formed to be parallel to the back surface 77a of the battery cover 72, for example.

Further, the rear end locking portion 82 is formed on the side wall portion of the rear case 73 on the hinge portion 75 side, and as shown in FIGS. 7 and 9, the front end portion of the rear end claw portion 78 is inserted into a substantially rectangular cross section. A concave portion 86 having a shape and a protruding portion 87 are provided.
The protrusion 87 has a lower surface 87a where the upper surface 78q of the hook portion 78b of the side end claw portion 78 faces or abuts, and a front end surface 78p of the hanging portion 78a of the side end claw portion 78 which is perpendicular to the lower surface 87a. And a rear end face 87b in contact therewith. The lower surface 87a is formed, for example, so as to be parallel to the bottom surface of the concave portion of the battery storage unit.

  The concave portion 86 has a bottom surface 86a where the lower surface 78r of the hook portion 78b of the side end claw portion 78 faces or slides, and a front end surface 78s of the hook portion 78b of the side end claw portion 78 which is perpendicular to the bottom surface 86a. And an inner wall surface 86b. For example, the bottom surface 86a is formed to be parallel to the bottom surface of the concave portion of the battery storage unit.

  The rear end claw portion 78 is formed in a bowl shape in a hanging state from the rear end portion of the battery cover 72, and is supported by a hanging portion 78a hanging from the back surface 72a side of the battery cover 72 and the hanging portion 78a. And a hook portion 78b provided in a protruding manner.

The hanging portion 78a has a front end surface 78p with which the rear end surface 87b of the protrusion 87 faces or abuts. The hook portion 78b includes an upper surface 78q on which the lower surface 87a of the protrusion 87 faces or abuts, a lower surface 78r that faces or slides on the bottom surface 86a of the recess 86, and an inner wall surface of the recess 86 perpendicular to the lower surface 78r. The front end surface 78s faces or abuts on the 86b.
The upper surface 78q and the lower surface 78r are formed to be parallel to the rear surface 72a of the battery cover 72, for example.

Due to the contact between the lower surface 87a of the protrusion 87 and the upper surface 78q of the hook portion 78b, the upward displacement of the battery cover 72 is restrained against the force to lift the battery cover 72.
Here, a groove portion 88 is formed at a contact portion between the bent portion on the outer surface side of the rear end claw portion 78 and the rear case 73.
As will be described later, when charging the battery pack of the mobile phone 1A, the mobile phone 1A is attached to a dedicated charger 91 (see FIGS. 10 to 14).

With the cellular phone 1A in a folded state, with the lower unit facing down, the side on which the external terminal is formed is applied to the external terminal side support portion 93, and the external terminal for receiving power is brought into contact with the connection terminal 97, From this state, the hinge part 75 side is rotated downward with the side where the external terminal is formed as a fulcrum, and the hinge part 75 side is pressed against the hinge side support part 92.
As a result, the tip of the lock arm portion 95 is fitted into the fitting recess of the cellular phone 1A, and the cellular phone 1A is held in a state where the connection terminal 97 is securely connected to the external terminal for receiving power.

However, since the groove portion 88 is formed on the lower side of the fitting recess portion, when the hinge portion 75 side is lowered, the groove portion 88 is moved before the tip of the lock arm portion 95 is abutted against the fitting recess portion. May be locked due to contact with the charger 91 and may be erroneously attached to the charger 91.
Is never done.
As described above, when the locking surface and the locked surface of the rear end locking portion and the rear end claw portion are parallel to the slide direction (substantially horizontal to the attached battery cover), The end locking portion 82 is formed on the side wall portion of the rear case 73 on the hinge portion 75 side. When the end cover 82 is attached to the charger 91, a part of the battery cover mounting structure 71 is part of the charger 91 of the mobile phone 1A. It will be a hindrance to the fixing function.
In order to solve this problem, in this example, the locking surface and the locked surface that are in contact with each other of the rear end locking portion and the rear end claw portion of the mobile phone 1 are inclined surfaces.

Next, the attachment and removal methods of the battery cover 33 and the function of the battery cover attachment structure 57 of the cellular phone 1 of this example will be described with reference to FIGS.
In order to attach the battery pack 26 to the mobile phone body, the terminal connection member 34 is attached to the recess 23 formed in the lower housing 9 so that the claw portion 35b fits into the fitting hole 27 for positioning. The battery pack 21 is fitted into the recess 23 by bringing the device body side contact piece 41 of the connection fitting 34 into contact with the device body side connection terminals 25, 25, 25. Finally, the battery cover 33 is attached.

In order to attach the battery cover 33, as shown in FIGS. 1 to 3, the battery cover 33 is inserted with the front end claw portion 51 inserted into the insertion hole 61 and the side end claw portion 52 inserted into the clearance portion 63 b. 33 is placed on the mounting portion 42, and the battery cover 33 is slid toward the distal end portion from this state.
Along with this sliding operation, the projecting portion 55 is fitted into the fitting recess 47, and the front end claw portion 51 is pushed by the projecting portion 61 so as to bend downward and get over the projecting portion 61. Then, the front end claw portion 51 returns to its original shape by the restoring force, and the front end claw portion 51 is locked by the front end locking portion 43 (the front end locking portion 43 and the front end claw portion 51 are engaged). Thereby, the rearward displacement of the battery cover 33 is restrained.

Further, as shown in FIG. 4, by sliding the battery cover 33 forward in a state where the battery cover 33 is placed on the placement portion 42 so that the side end claw portion 52 is inserted into the clearance portion 63b, The side end claw portion 52 is displaced so that the hook portion 52 b enters the storage portion 63 a below the projection portion 64, and the side end claw portion 52 is locked by the side end locking portion 44.
Here, the contact between the lower surface 64a of the protrusion 64 and the upper surface 52q of the hook portion 52b prevents the upward displacement of the battery cover 33 against the force to lift the battery cover 33.
Further, the battery cover 33 is displaced forward by contact between the rear end surface 64b of the protrusion 64 and the front end surface 52p of the hanging portion 52a, and contact between the inner wall surface 63q of the recess 63 and the front end surface 52s of the hook portion 52b. Stopped.

Further, as shown in FIG. 5, the battery cover 33 is slid forward in a state where the battery cover 33 is placed on the placement portion so that the rear end claw portion 53 is inserted into the recess 66 from the opening 67. As a result, the side end claw portion 52 is displaced so that the rear end claw portion 53 sinks below the lid portion 68 while the inclined surface 53p slides with respect to the inclined surface 68a. The end claw portion 53 is locked.
Here, due to the contact between the inclined surface 68a and the inclined surface 53p, the upward displacement of the battery cover 33 is restrained against the force of lifting the battery cover 33, and the battery cover 33 is moved forward. Displacement is restrained.
Note that the protrusion 54 is inserted into the guide groove 46 by sliding the battery cover 33 forward.

In order to remove the battery cover 33, the front end claw portion 51 is locked by the front end locking portion 43, the pressing portion 56 is pressed, and the front end claw portion 51 is bent downward. The engagement state where the front end claw portion 51 is locked by the front end locking portion 43 is released away from the protrusion 61 (the engagement relationship between the front end locking portion 43 and the front end claw portion 51 is released). The battery cover 33 is removed by sliding the battery cover 33 rearward (hinge side 4) in the state.
Further, when the hook portion 52b moves to the clearance portion 63b and is disengaged from the projection portion 64, the locking state in which the side end claw portion 52 is locked by the side end locking portion 44 is released (side locking). The engagement relationship between the portion 44 and the side claw portion 52 is released).

Further, when the rear end claw portion 53 moves to the concave portion 66 immediately below the opening 67 and is removed from the lid portion 68, the locked state in which the rear end claw portion 53 is locked by the rear end locking portion 45 is released. (The engagement relationship between the rear end locking portion 45 and the rear end claw portion 53 is released).
Further, by sliding the battery cover 33 backward, the projection 54 is gradually displaced upward by being guided by the inclined guide surface of the guide groove 46, and the rear end portion of the battery cover 33 is lifted and grasped by fingers. It becomes possible.

Next, a method for charging the battery pack 26 of the mobile phone 1 will be described with reference to FIGS.
When charging the battery pack 26 of the mobile phone 1, the mobile phone 1 is attached to a dedicated charger 91 as shown in FIGS. 7 to 11.
The charger 91 includes a hinge side support portion 92 that supports the hinge portion 4 side of the cellular phone 1 in a folded state, and an external terminal side support portion 93 that supports the side on which the external terminal opposite to the hinge portion 4 is formed. And have.

The hinge-side support portion 92 includes a cradle 74 on which the rear end portion of the rear case 32 is placed, and a lock arm portion 95 whose front end portion is elastically abutted against and fitted into the fitting recess 29. Yes.
The external terminal side support portion 93 is exposed from the opening 96 and is connected to an external terminal for power reception of the mobile phone 1, and a pair of holding portions 98 provided with a connection terminal 97 having a spring shape and a substantially U-shaped cross section. have.

First, the cellular phone 1 in the folded state of the cellular phone 1 is placed with the lower unit 3 facing downward, the side on which the external terminal is formed is applied to the external terminal side support portion 93, and the external terminal for receiving power is The contact terminal 97 is brought into contact, and from this state, the hinge part 4 side is rotated downward with the side on which the external terminal is formed as a fulcrum, and the hinge part 4 side is pressed against the hinge side support part 92.
As a result, the tip of the lock arm portion 95 is fitted into the fitting recess 29, and the mobile phone 1 is held in a state where the connection terminal 77 is securely connected to the external terminal for receiving power.
Here, since no groove or recess is formed on the lower side of the fitting recess 29, before the tip of the lock arm portion 95 is abutted against the fitting recess 29 when the hinge portion 4 is lowered. In addition, the charger 91 is locked in contact with the groove portion or the concave portion, and is not erroneously attached to the charger 91.

  Thus, according to the configuration of this example, the lower surface 64a and the bottom surface 63p are formed, for example, so as to be parallel to the bottom surface 34a of the concave portion 34, and the upper surface 52q and the lower surface 52r are formed, for example, of the battery cover 33. Since it is formed so as to be parallel to the back surface 33a and the outer surface 33b, the setting and adjustment of the dimensions of the respective portions of the side end locking portion 44 and the side end claw portion 52 are along the slide direction. When the axis is selected as the reference axis (for example, the x-axis), for example, the dimension along the sliding direction (the x-axis coordinate) and the direction orthogonal to the sliding direction (for example, the thickness direction of the battery cover 33) Therefore, it is possible to adjust the engagement relationship between the side end locking portion 44 and the side end claw portion 52 quickly and easily. Therefore, for example, it can contribute to shortening the development period.

  In addition, the rear end locking portion 45 and the rear end claw portion 53 have inclined surfaces 68a and 53p facing each other, both inclined with respect to the sliding direction, with the battery cover 33 attached to the rear case 32. Therefore, there is no need to form the rear end locking portion 45 on the side wall portion of the rear case 32. Therefore, no groove or concave portion is formed below the fitting concave portion 29. When lowering toward the charger 91, the lock arm 95 is locked in contact with the groove or the recess before the tip of the lock arm 95 is abutted against the fitting recess 29. It can be prevented from being performed.

  When the side end claw portion 52 is locked by the side end locking portion 44, the battery cover 33 is placed on the mounting portion 42 so that the side end claw portion 52 is inserted into the clearance portion 63 b of the side end locking portion 44. When the battery cover 33 is slid forward in the state of being placed on the side end claw 52, the side end claw portion 52 is displaced so that the hook portion 52b enters the storage portion 63a below the protrusion 64. Since the portion 52 is not inserted while pushing the inclined surface, it can be slid with a relatively small force, the side end claw portion 52 can be easily inserted, and the battery cover 33 can be easily and smoothly inserted into the rear case. 32 can be attached.

FIG. 15 is an exploded perspective view for explaining the configuration of the mobile phone according to the second embodiment of the present invention, and FIG. 16 is a diagram showing the configuration of the decorative cover of the mobile phone, and the back surface thereof. It is the perspective view seen from the side.
This example is greatly different from the first embodiment described above in that the cover plate is applied to a decorative cover mounting structure instead of a lid-shaped battery cover.

As shown in FIG. 15, a mobile phone 1B of this example is detachably mounted with a decorative cover 103 with a predetermined pattern and color on a mobile phone body 102 having a foldable casing 101. It is roughly structured.
The mobile phone main body 102 includes an upper unit 104 and a lower unit 105 that are connected to each other by a hinge unit 106 so as to be freely opened and closed.

  The decorative cover 103 has a back surface 103 a placed on the placement surface 108 of the rear case 107 of the upper unit 104, and on the placement surface 108 along the length direction of the rear case 107. The rear case is slid toward the side where the hinge portion 106 is formed and a predetermined portion is locked by the front end locking portion 109, the intermediate locking portion 111, and the rear end locking portion 112. 107, each projecting on the back surface 103a side, respectively, a front end claw portion 113 locked by a front end locking portion 109, an intermediate claw portion 114 locked by a pair of intermediate locking portions 111, And a rear end claw portion 115 that is locked by the rear end locking portion 112.

  As shown in FIGS. 15 and 16, the decorative cover mounting structure of this example is configured so that the decorative cover 103 is placed on the mounting surface 108 from the rear case 107 in a state where the back surface 103 a side is mounted on the mounting surface 108. The front end claw portion 113, the intermediate claw portion 114, and the rear end claw portion 115 are slid from the front end side to the side where the hinge portion 106 is formed along the length direction of the mounting surface 108. By being locked by a front end locking portion 109, an intermediate locking portion 111, and a rear end locking portion 112 formed on the upper side, the rear case 107 is detachably mounted and is roughly configured. Yes.

  Here, when the front end claw portion 113 is locked by the front end locking portion 109, the rearward, forward and upward displacement of the decorative cover 103 is stopped, and the intermediate locking portion 111 engages the intermediate claw portion 114. By being stopped, the front, side and upward displacement of the decorative cover 103 is restrained, and the rear end claw portion 115 is locked by the rear end locking portion 112, so that the front of the decorative cover 103 is stopped. The decorative cover 103 is attached to the rear case 107 in a state where the lateral and upward displacement is restrained and positioned.

In this example, the intermediate locking portion 111 and the intermediate claw portion 114 are both in a state in which the decorative cover 103 is attached to the rear case 107, respectively, It has a locked surface.
The rear end locking portion 112 and the rear end claw portion 115 are both locking surfaces that are inclined at a predetermined inclination angle with respect to the sliding direction in a state where the decorative cover 103 is attached to the rear case 107. And a locked surface.

  According to the configuration of this example, substantially the same effect as that of the first embodiment described above can be obtained.

The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and there are design changes and the like without departing from the gist of the present invention. Are also included in the present invention.
For example, in the above-described embodiments, among a plurality of pairs of locking portions and locked pieces, a part of the locking portions and the locked pieces are both opposed to each other with the locking surfaces inclined with respect to the sliding direction and Although the case where the locking portion and the locked piece having the locked surface are formed has been described, the locking surfaces facing each other are substantially parallel to the sliding direction for all the locking portions and the locked pieces. And the latching | locking part which has a to-be-latched surface, and a to-be-latched piece may be formed.

For example, in the first embodiment, if the trouble of the two-stage lock is eliminated, the locking portion of the rear end portion and the locking surface of the locked piece and the locked surface are slid together. You may form so that it may become substantially parallel with respect to a direction.
For cover plates other than the battery cover, all the locking portions and the locked pieces are substantially parallel to each other in the sliding direction, regardless of the structure in the vicinity, if they do not interfere with other functions. You may make it form the latching | locking part and to-be-latched piece which have the latching surface and to-be-latched surface which oppose.

In the first embodiment, the side end locking portion and the side end claw portion may be left-right asymmetric. For example, of the pair of left and right side end locking portions and side end claw portions, the locking surface and the locked surface of one side end locking portion and the side end claw portion are substantially parallel to the sliding direction, You may make it incline the locking surface and to-be-latched surface of this side edge latching | locking part and side edge nail | claw part with respect to a sliding direction.
Moreover, you may make it arrange | position alternately at right and left both sides along a slide direction.
For example, the cover plate is not limited to the battery cover, and may be applied to an SD slot cover, for example.

Further, the displacement in the lateral direction may be restrained by the engagement between the front end locking portion and the front end claw portion.
Further, for example, the side end locking portion and the side end claw portion are not limited to a pair, and a plurality of pairs may be provided.
In the second embodiment, the decorative cover may constitute a part of a housing (a front case or a rear case (rear cover)).
