The second insertion hole 37b is formed in the side wall portion of the main body case 30 on the negative direction side of the X axis. That is, the first insertion hole 37a and the second insertion hole 37b are arranged so as to be close to each other. For this reason, the first insertion hole 37a and the second insertion hole 37b are formed at corners including the bottom of the body case 30 . Although a plurality of second insertion holes 37b are formed in the present embodiment, only one may be formed.

FIG. 4 is a perspective view showing the wiring device 1 inside the main body cover 10 when the locking state of the pressing member 60 of the wiring device 1 according to the embodiment is released.

As shown in FIGS. 3 and 4, the body case 30 is formed with a housing chamber 35 for housing the terminal device 3 . The accommodation chamber 35 communicates with the first insertion hole 37a and the second insertion hole 37b.

A plurality of protrusions are formed on the bottom of the main body case 30 .

As will be described later, when the pressing member 60 is in a locked state (locked by the locking portion 33), the locking portion 33 is inserted into the concave portion 63 of the pressing member 60 and is caught. , the movement of the pressing member 60 in the negative direction of the X-axis can be suppressed.

[Terminal device 3]
As shown in FIGS. 2B, 3 and 4, the terminal device 3 is arranged in the housing 5 for electrical connection with the electric wire 90 inserted from the first insertion hole 37a formed in the housing 5. .

The terminal device 3 includes a terminal 40 , a locking spring 50 , a pressing member 60 and a transmission member 70 .

The terminal 40 is a quick-connect terminal capable of housing the locking spring 50 inside. The terminal 40 is accommodated in a housing chamber for the terminal 40, and includes a terminal plate 41 electrically connected to the electric wire 90, an opposing plate 42 disposed on the opposite side of the terminal plate 41 via the locking spring 50, and a terminal It has a connection portion 43 that connects the plate 41 and the opposing plate 42 . In the terminal 40 , when the electric wire 90 is inserted through the first insertion hole 37 a of the main body case 30 , the electric wire 90 pressed against the locking spring 50 and the terminal plate 41 are electrically connected.

In this embodiment, the terminal 40 has a pair of terminal plates 41 . A slit 44 is formed between the pair of terminal plates 41 to allow the locking spring 50 housed in the terminal 40 to be exposed. A transmission member 70 is inserted into the slit 44 .

The locking spring 50 electrically connects the electric wire 90 and the terminal 40 by elastically contacting the electric wire 90 inserted from the first insertion hole 37a. The locking spring 50 is arranged to face the first insertion hole 37a. That is, the locking spring 50 is exposed when viewed along the Z-axis direction. The locking spring 50 is an example of an elastic member.

FIG. 5A is a perspective view showing a case where the locking state of the pressing member 60 of the terminal device 3 according to the embodiment is released. FIG. 5B is a perspective view showing a case where the pressing member 60 of the terminal device 3 according to the embodiment is in the locked state. FIG. 6A is a cross-sectional view taken along line AA of FIG. 1 showing a case where the locking state of the pressing member 60 of the wiring device 1 is released. FIG. 6B is a cross-sectional view showing the case where the pressing member 60 of the wiring device 1 is in the locked state.

As shown in FIGS. 5A to 6B, the locking spring 50 is arranged at a position facing the S-shaped connecting piece 51 and the opening of the first insertion hole 37a when viewed along the Y-axis direction. and a center piece 53 that connects the connecting piece 51 and the locking piece 52 and is held by the opposing plate 42 of the terminal 40 . The lock piece 52 is exposed from the first insertion hole 37a. The connecting piece 51 and the locking piece 52 are arranged so as to face or contact the terminal plate 41 of the terminal 40 . The connecting piece 51 and the locking piece 52 can indirectly press the terminal plate 41 of the terminal 40 via the electric wire 90 . Note that the locking spring 50 may not have the connection piece 51 , and the connection piece 51 is not an essential component of the locking spring 50 .

The locking spring 50 is elastically deformed when the transmission member 70 inserted into the slit 44 of the terminal 40 is pressed along the pressing direction (X-axis plus direction). Specifically, since the connecting piece 51 and the locking piece 52 of the locking spring 50 are in contact with the transmission member 70, the pressing member 60 is pressed along the pressing direction, thereby The member 70 moves in the positive direction of the X axis, the connecting piece 51 and the locking piece 52 are elastically deformed (in an elastically deformed state), and the connecting piece 51 and the locking piece 52 are separated from the terminal plate 41 of the terminal 40. , a gap into which the electric wire 90 can be inserted is formed. Accordingly, by inserting the electric wire 90 from the first insertion hole 37a, the electric wire 90 can be arranged between the terminal plate 41 and the connecting piece 51 and the locking piece 52. As shown in FIG. In other words, the locking spring 50 can be displaced by elastic deformation to a state in which the wire 90 can be inserted so that the wire 90 can be electrically connected to the terminal 40 .

In this embodiment, as shown in FIGS. 6A and 6B, the locking spring 50 has a pair of connecting pieces 51, a pair of locking pieces 52, and a pair of central pieces 53. The pair of connecting pieces 51 and the pair of locking pieces 52 are in one-to-one correspondence with the pair of terminal plates 41 . That is, since the pair of connecting pieces 51 and the pair of locking pieces 52 are in one-to-one correspondence with the two adjacent first insertion holes 37a, the pressing member 60 and the transmission member 70 are pressed along the pressing direction. Then, the pair of connecting pieces 51 and the pair of locking pieces 52 are elastically deformed. When the pair of connecting pieces 51 and the pair of locking pieces 52 are elastically deformed, the wires 90 can be simultaneously inserted into and removed from the two adjacent first insertion holes 37a.

The locking spring 50 may have three or more connecting pieces 51, three or more locking pieces 52, and three or more central pieces 53. Moreover, the terminal plate 41 may also have three or more so as to correspond one-to-one with the three or more connection pieces 51 and the three or more locking pieces 52 . Also, the three or more connecting pieces 51 and the three or more locking pieces 52 may correspond one-to-one with the three or more first insertion holes 37a. Therefore, by pressing one pressing member 60, the electric wires 90 may be simultaneously inserted into and removed from three or more first insertion holes 37a.

In addition, in the present embodiment, one locking spring 50 corresponds to two first insertion holes 37a, but it is not limited to this. For example, one locking spring 50 may correspond to three or more first insertion holes 37a, and one locking spring 50 may correspond to one first insertion hole 37a. One locking spring 50 may be elastically deformed by one or more pressing members 60 and one or more transmission members 70 .

FIG. 7A is a cross-sectional view taken along the line BB in FIG. 6A showing the case where the pressing member 60 of the wiring device 1 is released from the locking state. FIG. 7B is a cross-sectional view showing the case where the pressing member 60 of the wiring device 1 is in the locked state. FIG. 8A is a cross-sectional view taken along line CC of FIG. 6A showing a case where the locking state of the pressing member 60 of the wiring device 1 is released. FIG. 8B is a cross-sectional view showing the case where the pressing member 60 of the wiring device 1 is in the locked state. FIG. 8C is a cross-sectional view showing the electric wire 90 when the locking state of the pressing member 60 of the wiring device 1 is released.

As shown in FIGS. 7A to 8C, the pressing member 60 is held by the body case 30 while being inserted into the second insertion hole 37b of the body case 30. As shown in FIGS. Since the head portion 62 of the pressing member 60 is exposed from the main body case 30, the pressing member 60 is pressed along the pressing direction. When the pressing member 60 is pressed in the pressing direction and the locking spring 50 is elastically deformed, when the locking portion 33 rotates at the first angle, the locking portion 33 moves from the first concave portion 63a of the pressing member 60 to the second concave portion 63b. , the locking portion 33 is locked to the second recess 63b. In other words, the pressing member 60 is pressed by the tool 91 and rotated at the first angle, thereby being locked by the locking portion 33 of the main body case 30 and entering a locked state in which movement is restricted. Therefore, when the concave portion 63 is not locked by the locking portion 33 (locked state is released), the first insertion hole 37a and the locking spring 50 are positioned so as to face the opening surface of the first insertion hole 37a. When viewed, the pressing member 60 is indirectly or directly pressed in the pressing direction, thereby elastically deforming the locking spring 50 into a state in which the electric wire 90 can be inserted and removed. The area of the locking spring 50 overlapping the first insertion hole 37a is reduced. When the pressing member 60 rotates at the first angle and the locking portion 33 is inserted from the first recess 63a into the second recess 63b, the pressing member 60 is in the locked state.

When the pressing member 60 is in the locked state in which the recessed portion 63 is locked by the locking portion 33, the pressing member 60 rotates at the second angle so that the locking portion 33 is inserted from the second recessed portion 63b into the first recessed portion 63a. Then, the locked state is released. That is, when the locked state is released by being rotated at the second angle by the tool 91, the pressing member 60 is pressed by the elastic force of the locking spring 50 and moves in the negative direction of the X axis. Therefore, in a state where the recessed portion 63 is locked by the locking portion 33 (locked state), the pressing member 60 rotates at the second angle so that the locking portion 33 moves from the second concave portion 63b to the first concave portion 63a. When inserted, the locked state is released, and when the first insertion hole 37a and the locking spring 50 are viewed so as to face the opening surface of the first insertion hole 37a, the locking spring 50 returns to its original state. Then, the area of the region of the locking spring 50 that overlaps the first insertion hole 37a is increased. As a result, if the electric wire 90 is inserted into the first insertion hole 37a, the electric wire 90 is sandwiched between the terminal 40 and the locking spring 50, so that the electric wire 90 is inserted into the terminal device 3 while being electrically connected to the terminal 40. Fixed.

Here, the first angle may be the same as or different from the second angle. Therefore, the direction of rotation for rotating at the first angle may be different from or the same as the direction of rotation for rotating at the second angle.

As shown in FIGS. 5A to 7B, the pressing member 60 has a pressing shaft portion 61 and a head portion 62. As shown in FIGS.

The pressing shaft portion 61 is a long shaft-shaped member extending along the X-axis direction, and the end portion on the X-axis plus direction side is in contact with the transmission member 70 . Also, the end portion of the pressing shaft portion 61 on the negative direction side of the X axis is connected to the head portion 62 .

The head portion 62 is connected to the pressing shaft portion 61 and pressed by the tool 91 to press the pressing shaft portion 61 against the locking spring 50 . That is, an engaging portion 62a that can be engaged with the tool 91 is formed at the end portion of the head portion 62 opposite to the locking spring 50 side. The engaging portion 62a is a concave portion such as a groove or a hole, or a convex portion such as a projecting piece.

As a result, the engaging portion 62a of the head portion 62 is engaged with the tool 91, so that the pressing member 60 can be pressed in the pressing direction or rotated at the first angle or the second angle. That is, the head 62 is arranged in the second insertion hole 37b, and when pressed by the tool 91, moves in the positive direction of the X axis and enters the second insertion hole 37b. Further, when the locked state is released, the head 62 moves in the negative direction of the X axis due to the elastic force of the locking spring 50 .

Also, the pressing member 60 has a recess 63 . In this embodiment, the recess 63 is formed in the pressing shaft portion 61 .

The recessed portion 63 is formed on the outer peripheral surface of the pressing shaft portion 61 and recessed in the vertical direction, which is the direction perpendicular to the pressing direction. In the present embodiment, the locking portion 33 is always inserted into the concave portion 63 .

The recessed portion 63 has a first recessed portion 63a formed along the pressing direction and a second recessed portion 63b formed along the vertical direction and connected to the first recessed portion 63a.

The first concave portion 63a is a groove-shaped or hole-shaped concave portion extending along the X-axis direction. When the locking portion 33 is inserted into the first concave portion 63a, the pressing member 60 is pressed in the pressing direction, thereby elastically deforming the locking spring 50. As shown in FIG. When the locking portion 33 is inserted into the first concave portion 63a, the pressing member 60 is released from the locked state and can move in the X-axis direction. The second recess 63b is a groove-shaped or hole-shaped recess formed along the circumferential direction of the pressing shaft portion 61 from the end of the first recess 63a on the head 62 side. The second recess 63b is continuous with the end portion of the first recess 63a on the head 62 side, and is formed so as to insert the engaging portion 33 also at the boundary with the first recess 63a. When the locking portion 33 is inserted into the second concave portion 63b, the pressing member 60 is locked by the locking portion 33 being caught in the second concave portion 63b, so that the locking spring 50 is elastically deformed. It will be in a locked state in which the state is maintained.

The first recessed portion 63a and the second recessed portion 63b can be guided by the locking portion 33 to switch between a locked state and a state where the locked state is released. The shapes of the first recess 63a and the second recess 63b are not particularly limited as long as the locking portion 33 is inserted therein.

In the present embodiment, the first concave portion 63a is formed in the pressing shaft portion 61 and extends by a predetermined length from the end portion of the pressing shaft portion 61 on the positive direction side of the X axis. The second recess 63b is continuous with the first recess 63a, is formed in the pressing shaft portion 61, and is formed along the circumferential direction of the pressing shaft portion 61. As shown in FIG. Therefore, when the pressing member 60 rotates at the first angle, the second concave portion 63b is guided by the locking portion 33, so that the pressing member 60 is locked at the first angle about the X axis. The portion 33 rotates in the first rotation direction, which is the rotation direction in which the portion 33 is inserted into the second recess 63b. Further, when the pressing member 60 rotates in the second rotating direction opposite to the first rotating direction, the second concave portion 63b is guided by the locking portion 33, so that the pressing member 60 rotates about the X axis. , the locking portion 33 rotates in the second rotation direction, which is the rotation direction in which the locking portion 33 is inserted into the second recess 63b. Note that the first rotation direction may be the same direction as the second rotation direction.

In the present embodiment, the recess 63 is L-shaped, T-shaped, or the like, for example. However, the concave portion 63 is not limited to an L-shape, a T-shape, or the like. At least the recessed portion 63 has a first recessed portion 63a and a second recessed portion 63b that is continuous with the first recessed portion 63a. . In addition, in the present embodiment, the direction in which the second recess 63b extends is perpendicular to the direction in which the first recess 63a extends.

The transmission member 70 is an elongated columnar member along the Z-axis direction and is inserted into the slit 44 of the terminal 40 . The transmission member 70 is positioned between the pressing member 60 and the locking spring 50 and is in contact with at least the pressing member 60 . That is, the transmission member 70 is sandwiched between the pressing member 60 and the locking spring 50 . Specifically, the transmission member 70 abuts on the end portion of the pressing shaft portion 61 of the pressing member 60 on the X-axis plus direction side, and the one or more connecting pieces 51 and the one or more locking pieces 51 of the locking spring 50 . It is in a state of being in contact with the piece 52 . Therefore, the transmission member 70 can elastically deform the locking spring 50 by transmitting the pressing force from the pressing member 60 to the locking spring 50 . Moreover, since the transmission member 70 transmits the elastic force from the locking spring 50 to the pressing member 60, the pressing member 60 can be moved in the direction opposite to the pressing direction (minus direction of the X axis).

In the present embodiment, the transmission member 70 is in contact with the pair of connecting pieces 51 and the pair of locking pieces 52, but is not limited to this. For example, the transmission member 70 is in contact with the three or more connecting pieces 51 and the three or more locking pieces 52, and simultaneously elastically engages the three or more connecting pieces 51 and the three or more locking pieces 52. It may be deformable.

The transmission member 70 is formed with a recessed engaging recess 71 that engages with the pressing member 60 and a mountain portion 72 that contacts the locking piece 52 of the locking spring 50 .

The engaging recess 71 is formed on the surface of the transmission member 70 on the pressing member 60 side (the surface on the negative side of the X axis). The engaging concave portion 71 is engaged with the pressing shaft portion 61 by inserting the pressing shaft portion 61 of the pressing member 60 . This makes it easier to maintain the postures of the pressing member 60 and the transmission member 70 .

The peak portion 72 is formed on the surface of the transmission member 70 on the locking spring 50 side (the surface on the positive side of the X axis). The peak portion 72 can press the locking piece 52 of the locking spring 50 or suppress the movement of the locking piece 52 toward the first insertion hole 37a by pressing the pressing member 60. good too.

In the present embodiment, the pressing member 60 and the transmission member 70 are separable separate configurations, but the pressing member 60 and the transmission member 70 may be configured integrally.

<Action>
Next, a case of electrically connecting the electric wire 90 to the terminal device 3 according to the present embodiment will be described.

First, as shown in FIG. 2A, the operator engages the tip of the tool 91 with the engaging portion 62a of the head 62 of the pressing member 60, and pushes the tool 91 in the positive direction of the X axis. 6A, 6B, 8A and 8B, the pressing member 60 and the transmission member 70 are pressed along the pressing direction, and the pressing force is transmitted to the locking spring 50. , the locking spring 50 is elastically deformed. Specifically, the connecting piece 51 and the locking piece 52 of the locking spring 50 are elastically deformed, and the width (thickness) of the locking spring 50 in the X-axis direction is reduced. Then, when the first insertion hole 37a and the locking spring 50 are viewed so as to face the opening surface of the first insertion hole 37a, the area of the region of the locking spring 50 that overlaps with the first insertion hole 37a decreases, and the connection By separating the piece 51 and the locking piece 52 from the terminal plate 41 of the terminal 40, a gap into which the electric wire 90 can be inserted is formed.

Next, the operator rotates the tool 91 by a first angle in the first rotation direction, as shown in FIG. 2B. As a result, as shown in FIGS. 5B, 6B, and 7B, the pressing member 60 rotates by the first angle in the first rotation direction with respect to the transmission member 70, so that the concave portion 63 of the pressing member 60 also rotates in the first rotation direction. Rotate by the first angle to . At this time, since the locking portion 33 is arranged from the first recess 63a to the second recess 63b of the recess 63, movement of the pressing member 60 in the X-axis direction is restricted. Thus, the pressing member 60 is locked.

In this way, the operator can remove the tool 91 from the pressing member 60 and release it, and then insert/remove the electric wire 90 into/from the first insertion hole 37a.

For example, when it is desired to electrically connect the electric wire 90 to the terminal device 3 , the electric wire 90 can be inserted between the connection piece 51 and the locking piece 52 and the terminal plate 41 of the terminal 40 with the pressing member 60 in the locked state. A gap can be formed, and the electric wire 90 can be inserted into the first insertion hole 37a.

Next, the operator engages the tip of the tool 91 with the engaging portion 62a of the head 62 of the pressing member 60, and rotates the tool 91 by the second angle in the second rotation direction. As a result, the pressing member 60 rotates by the second angle in the second rotation direction with respect to the transmission member 70, so that the recess 63 of the pressing member 60 also rotates by the second angle in the second rotation direction. At this time, the locking portion 33 is arranged at the boundary portion between the second recessed portion 63b and the first recessed portion 63a, and the locked state is released. Thus, the pressing member 60 can move in the X-axis direction.

Since the pressing member 60 is pressed in the negative direction of the X axis by the elastic force of the locking spring 50, it moves in the negative direction of the X axis together with the transmission member 70 when the locked state is released. The locking portion 33 is inserted into the first concave portion 63a, and the pressing member 60 and the transmission member 70 return to their original postures.

At this time, the electric wire 90 is pressed against the terminal plate 41 of the terminal 40 by the connecting piece 51 and the locking piece 52 and is sandwiched between the connecting piece 51 and the locking piece 52 and the terminal plate 41 of the terminal 40 . The electric wire 90 is thereby electrically connected to the terminal 40 .

Then, the operator removes the tool 91 from the pressing member 60 and releases it, thereby completing the attachment of the electric wire 90 to the wiring device 1 .

<Effect>
Next, the effects of the terminal device 3 according to this embodiment will be described.

As described above, the terminal device 3 of the present embodiment includes the terminal 40, the housing 5 formed with the first insertion hole 37a into which the electric wire 90 for electrical connection with the terminal 40 is inserted, and the first It includes a locking spring 50 that electrically connects the wire 90 and the terminal 40 by elastically contacting the wire 90 inserted from the insertion hole 37a, and a pressing member 60 that is pressed along the pressing direction. Further, the pressing member 60 has a concave portion 63 recessed in the vertical direction, which is the direction perpendicular to the pressing direction. When the first insertion hole 37a and the locking spring 50 are viewed so as to face the opening surface of the first insertion hole 37a, the pressing member 60 is pressed in the pressing direction, thereby making the locking spring 50 resilient. By deforming, the area of the region of the locking spring 50 that overlaps the first insertion hole 37a is reduced. The housing 5 has a locking portion 33 that locks the pressing member 60 by engaging with the concave portion 63 in a state where the pressing member 60 elastically deforms the locking spring 50 .

According to this, when the electric wire 90 is electrically connected to the terminal device 3, if the pressing member 60 is pressed, the locking spring 50 is elastically deformed to cover the first insertion hole 37a. area can be reduced. Further, even if the operator does not maintain the state of pressing the pressing member 60 , the locking spring 50 can be kept elastically deformed by locking the recess 63 to the housing 5 . Therefore, the operator can insert and remove the wire 90 with respect to the terminal device 3 using both hands.

Therefore, according to this terminal device 3, the insertion/removal work can be realized in a simple procedure.

In particular, even if the wire 90 is soft, the wire 90 can be inserted deep into the first insertion hole 37a and electrically connected to the terminal 40 without being bent by the locking spring 50. .

Further, in the terminal device 3 of the present embodiment, the recess 63 is continuous with the first recess 63a formed along the pressing direction and the first recess 63a formed along the direction intersecting the pressing direction. It has two recesses 63b.

According to this, the locking portion 33 inserted into the recess 63 can be positioned from the first recess 63a to the second recess 63b or from the second recess 63b to the first recess 63a. Therefore, it is possible to easily switch the pressing member 60 to the locked state or to release the locked state.

Further, the terminal device 3 of the present embodiment is provided with a transmission member 70 positioned between the pressing member 60 and the locking spring 50 and in contact with the pressing member 60 . The locking spring 50 is elastically deformed via the transmission member 70 .

According to this, it becomes possible to easily position the pressing member 60 with respect to the locking spring 50 by the transmission member 70 . Since the transmission member 70 can transmit the pressing force of the pressing member 60 to the locking spring 50, for example, when a plurality of locking springs 50 are arranged in the housing 5, the transmission member 70 can simultaneously transmit a plurality of locks. The lock spring 50 can be elastically deformed.

Further, when the pressing member 60 rotates, the end surface of the pressing member 60 contacts and slides on the surface of the transmission member 70 , so the end surface of the pressing member 60 directly contacts the locking spring 50 . As compared with the case of sliding, deterioration and damage of the pressing member 60 can be suppressed.

In addition, in the terminal device 3 of the present embodiment, when the engaging portion 33 is inserted into the first recess 63a, the pressing member 60 is pressed in the pressing direction, thereby causing the locking spring 50 to be elastic. Transform.

According to this, the locking spring 50 can be elastically deformed simply by pressing the pressing member 60, so that the electric wire 90 can be easily inserted from the first insertion hole 37a.

Further, in the terminal device 3 of the present embodiment, when the locking spring 50 is elastically deformed, the pressing member 60 rotates at the first angle so that the locking portion 33 is inserted into the second concave portion 63b. , and is locked to the locking portion 33 .

According to this, the pressing member 60 can be locked to the locking portion 33 only by rotating the pressing member 60 at the first angle after the operator presses the pressing member 60 . At this time, by locking the pressing member 60, the electric wire 90 can be pulled out from the terminal device 3 if the electric wire 90 is inserted into the first insertion hole 37a. If the electric wire 90 is not yet inserted into the one insertion hole 37a, the operation of inserting the electric wire 90 can be performed. Therefore, the terminal device 3 is excellent in workability.

In addition, in the terminal device 3 of the present embodiment, the pressing member 60 is arranged in the first insertion hole 37a so as to face the opening surface of the first insertion hole 37a in a state where the recessed portion 63 is locked by the locking portion 33 . And when the locking spring 50 is viewed, when the locking portion 33 is rotated at the second angle and the locking portion 33 is inserted into the first concave portion 63a, the locked state of the locking portion 33 is released, The area of the locking spring 50 overlapping the first insertion hole 37a is increased.

According to this, the locked state can be easily released simply by rotating the pressing member 60 at the second angle. When the locked state is released, the electric wire 90 can be electrically connected to the terminal 40 as long as the electric wire 90 is inserted into the first insertion hole 37a. Therefore, the terminal device 3 is excellent in workability.

Further, in the terminal device 3 of the present embodiment, the direction of rotation in which the engaging portion 33 is rotated at the first angle and inserted into the second recess 63b is rotated at the second angle and the engaging portion 33 is inserted into the second recess 63b. The direction of rotation is opposite to the direction of insertion into the recess 63a.

According to this, it is possible to prevent the operator from continuing to rotate the pressing member 60 . Therefore, in the terminal device 3, it is possible to suppress deterioration of workability in the insertion/removal work.

In addition, in the terminal device 3 of the present embodiment, the pressing member 60 has an engaging portion 62a that can be engaged with the tool 91 at the end opposite to the locking spring 50 side.

According to this, the tool 91 can be engaged with the engaging portion 62a of the pressing member 60, so that the alignment of the tool 91 with respect to the pressing member 60 is facilitated. Therefore, the pressing member 60 can be easily rotated using the tool 91 .
