Description

The present invention relates to trigger ejectors.

Conventionally, it has an operation lever called a trigger or the like, and by swinging the trigger in the front-rear direction, the built-in pump mechanism is operated, and the contents such as liquid sucked from the container body are pressure-fed to the nozzle head, BACKGROUND ART Trigger-type ejectors are known that eject contents in various forms such as spray, jet, and foam from a nozzle hole provided in a nozzle head.

Trigger-type ejectors of this type are often provided with a lock mechanism for suppressing leakage of contents from the nozzle hole due to erroneous operation of the trigger. For example, in Patent Document 1, by rotating the nozzle head, the discharge path of the contents and the nozzle holes are communicated, and when the nozzle head is returned to its original position, the contents are directed to the discharge path of the contents, that is, the nozzle holes. A locking mechanism is provided to close the flow path of the contents. When the flow path is closed by the lock mechanism, the lock mechanism is released by rotating the nozzle head in the opposite direction. On the peripheral wall of the nozzle head, printing indicating the rotation position of the nozzle head such as "out" and "stop" is performed. By checking the contents of the print, the user can grasp whether or not the contents can be ejected.

However, with the trigger-type ejector disclosed in Patent Literature 1, it is necessary to rotate the nozzle head directly by hand. For example, when the content is detergent or the like, if the content adheres to the nozzle head, the hand becomes slippery and it becomes difficult to perform the turning operation. Furthermore, if the content is a chlorine-based fungicide that is not desirable to adhere to the hands, it is not desirable to directly touch the nozzle head with the hands. Furthermore, it is necessary to check the printing of the nozzle head to see if the contents can be ejected at present, but if the printing becomes faint or bubbles adhere to the printed part, it is not possible to grasp it. Therefore, it was difficult to determine whether or not it was necessary to rotate the nozzle head.

[First embodiment]
A trigger-type ejector 100 according to a first embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of the trigger type ejector 100 of the first embodiment. The trigger-type ejector 100 is attached to the container body 1 in which the contents are accommodated, and includes a nozzle portion 10 having a nozzle hole 11 for ejecting the contents, and a frontwardly biased state that swings in the front-rear direction. The operation lever 21 is movably held, and when the operation lever 21 swings in the front-rear direction, the built-in pump mechanism operates, and the contents sucked from the container body 1 are ejected from the nozzle hole 11 by the pump action. and a shroud 30 (cover portion) that covers the nozzle portion 10 and the ejector body 20 . The contents are mainly liquids, and can be, for example, various liquids such as various detergents such as bath detergents, disinfectants, fungicides, and deodorants.

The trigger-type ejector 100 of this embodiment is provided with two types of lock mechanisms for preventing unintended ejection of the contents. As a first locking mechanism, the nozzle portion 10 incorporates a nozzle lock mechanism 40 that closes the flow path of the contents toward the nozzle hole 11 (hereinafter referred to as the content pumping flow path). Therefore, in each figure, the reference numerals of the nozzle lock mechanism 40 are shown in the vicinity of the nozzle portion 10 . By providing the nozzle lock mechanism 40 , it is possible to prevent the contents from unintentionally ejecting from the nozzle hole 11 due to an erroneous operation of the operation lever 21 . A lever lock mechanism 50 is provided as a second lock mechanism to disable unintended operation of the operation lever 21 . In this embodiment, the shroud 30 is rotatably attached to a shaft provided on the ejector body 20, and the shroud 30 can be positioned between the first position shown in FIG. 1 and the second position shown in FIG. , the locked state and the unlocked state by the nozzle lock mechanism 40 and the lever lock mechanism 50 can be switched. In this embodiment, the first position is in the locked state, and the second position is in the unlocked state.

The configuration of each unit will be specifically described below. In this specification, "top" and "bottom" indicate relative positional relationships, and when the trigger type ejector 100 is attached to the mouth portion 2 of the container body 1 via the attachment cap 60, , the side on which the trigger-type ejector 100 is positioned is referred to as "upper", and the side on which the container body 1 is positioned is referred to as "lower". Moreover, the “axial direction” means the direction of the central axis O of the mouth portion 2 of the container body 1 . Further, it is assumed that the contents are ejected in a direction substantially orthogonal to the axial direction, the side on which the nozzle holes 11 are provided is called the "front" side, and the opposite side is called the "rear" side. In the example shown in FIG. 1, since the nozzle holes 11 are arranged so as to face the left side as viewed in the drawing, the left side is referred to as the front side and the right side as the rear side.

The shape and the like of the container body 1 are not particularly limited as long as the container body 1 can accommodate the contents, and conventionally known configurations can be appropriately adopted. Moreover, it is preferable that the container body 1 and the mounting cap 60 are, for example, screwed together so that the trigger-type ejector 100 is detachably mounted on the container body 1 .

The ejector body 20 has a main cylinder (not shown) which is provided so as to stand upright in the axial direction with respect to the mounting cap 60, and a discharge valve at the upper part of the main cylinder, which is substantially perpendicular to the axial direction of the main cylinder. It is provided with an injection cylinder (not shown) provided in the opposite direction, and a suction tube (not shown) connected to the lower end (suction end) of the main cylinder via a suction valve. A suction tube is inserted into the container body 1 . In addition, a cylinder tube 22 is provided in a direction substantially perpendicular to the axial direction of the main tube at the lower portion of the main tube. The cylinder cylinder 22 communicates with the space between the suction valve and the discharge valve of the main cylinder. A plunger 23 that slides airtightly and liquid-tightly on the inner peripheral surface of the cylinder cylinder 22 is provided in the cylinder cylinder 22, and these constitute a pump mechanism.

The operation lever 21 is held so as to be able to swing back and forth with respect to the ejector body 20 about a shaft portion (not shown) provided on the ejector body 20 as a pivot center. In this embodiment, the operating lever 21 is connected to the plunger 23 while being biased forward by a resin spring piece 24 .

The spring pieces 24 are arranged on both sides of the operating lever 21, respectively. As shown in FIG. 2, each spring piece 24 has a shape in which two curved pieces are arranged substantially in parallel and connected at the bottom. A projecting portion 24a projecting downward is provided at the lower portion of the spring piece 24. As shown in FIG. The upper part of the spring piece 24 is fixed to the ejector body 20 in front of the swing center of the operating lever 21, and the projecting part 24a at the lower part is inserted into the pocket 21a provided behind the operating lever 21, It is configured to come into contact with an abutting member disposed within the pocket 21a.

When the operation lever 21 is pulled backward, the plunger 23 is pushed into the cylinder cylinder 22 . When the pulling operation of the operating lever 21 is released, the operating lever 21 and the plunger 23 are biased forward by the spring piece 24, so that they return to their original positions. As the operating lever 21 swings back and forth in this manner, the plunger 23 reciprocates within the cylinder tube 22, and the contents sucked from the container body 1 by the pumping action of these move through the ejection tube to the nozzle. It is pumped to part 10.

The nozzle portion 10 has an ejection surface 12 formed with the nozzle hole 11 on one side, and a rotating cylinder 13 on the other side which is rotatable with respect to the injection cylinder.

The nozzle lock mechanism 40 is a lock mechanism for closing the contents pressure-feeding channel to prevent the contents from being ejected from the nozzle hole 11, and opens and closes the contents pressure-feeding channel according to the rotation position of the rotating cylinder 13. configured to The nozzle lock mechanism 40 includes, for example, a connecting cylinder (not shown) that connects the injection cylinder and the rotating cylinder 13 and to which the rotating cylinder 13 is rotatably mounted. a second flow path communicating with the passage and the nozzle hole 11; can be done. The state in which the content pumping channel is closed is called the locked state by the nozzle lock mechanism 40, and the state in which the content pumping channel is open is called the unlocked state by the nozzle lock mechanism 40.

The shroud 30 covers the nozzle portion 10 and the ejector body 20 as described above, and is rotatably attached to the rotating shaft 25 provided on the ejector body 20 . As shown in FIG. 1, the rotating shaft 25 is provided in the lower part of the shroud 30 and in the vicinity of the connecting portion between the container body 1 and the mounting cap 60 . It is substantially orthogonal to the central axis O. As shown in FIG. 3A, the shroud 30 has a top wall 31 that covers the top of the nozzle portion 10 and the ejector body 20 while in contact with the nozzle portion 10 at the first position. Further, the top wall 31 is provided with nozzle portion side walls 32 covering both sides of the nozzle portion 10 and ejector main body side walls 33 covering both sides of the ejector main body 20 . As shown in FIGS. 3A and 3B, the wall surface of the nozzle portion side wall 32 is arranged inside the wall surface of the ejector main body side wall 33, and one nozzle portion side wall 32 (the nozzle portion on the front side in FIG. 1) A guide groove 71 for a link mechanism 70, which will be described later, is provided in the side wall 32). Furthermore, as shown in FIG. 4( a ), the shroud 30 has a rear wall 34 that covers the rear side of the ejector body 20 . The rear wall 34 is connected to the top wall 31, the nozzle side wall 32, and the ejector main body side wall 33, respectively. The front side of the shroud 30 is open so that the ejection surface 12 of the nozzle portion 10 is exposed.

At the first position shown in FIGS. 1, 3A, and 4A, the nozzle portion 10 is in contact with the ceiling wall 31 and the nozzle portion side walls 32, and the nozzle portion 10 is covered from three directions. Also, in the first position, the ejector body 20 is covered by the top wall 31, the ejector body side walls 33 and the rear wall 34 except for a part of the lower part.

On the other hand, in the second position shown in FIGS. 2, 3(b) and 4(b), the shroud 30 rotates around the rotation shaft 25, so that the nozzle portion side wall 32 moves upward while drawing an arc. move to Therefore, the nozzle portion 10 and the ceiling wall 31 are separated by a predetermined distance, and most of the nozzle portion 10 is exposed. The ejector main body side wall 33 moves upward while drawing an arc on the front side of the rotating shaft 25, and moves downward while drawing an arc on the rear side. The rear wall 34 moves downward with them. Therefore, the lower portion of the ejector body 20 exposed from the shroud 30 in the first position is covered with the ejector body side wall 33 and the rear wall 34 as the shroud 30 rotates.

Since the shroud 30 is configured as described above, in order to displace the shroud 30 from the first position to the second position, for example, the nozzle portion side wall 32 is grasped and the shroud 30 is pushed upward. . Further, in order to displace the shroud 30 from the second position to the first position, for example, the ceiling wall 31 may be pushed down on the nozzle section 10 side.

The lever lock mechanism 50 is composed of a substantially semi-disc-shaped contact piece 51 that protrudes downward from the side wall of the shroud 30 . As shown in FIG. 1, in the first position, the contact piece 51 is arranged at a position in contact with or close to the operating lever 21, the pulling operation of the operating lever 21 is disabled, and the operating lever 21 swings rearward. is regulated. This state is called a locked state by the lever lock mechanism 50 . Further, as shown in FIG. 2, at the second position, the contact piece 51 moves upward together with the shroud 30 and is displaced to a position where it does not come into contact with the operation lever 21 even if it swings rearward. Can be towed. This state is referred to as an unlocked state by the lever lock mechanism 50 .

The link mechanism 70 is a mechanism that connects the shroud 30 and the nozzle lock mechanism 40 and converts the displacing operation of the shroud 30 into the opening and closing operation of the content pumping channel by the nozzle lock mechanism 40 . In the present embodiment, the link mechanism 70 is provided so as to protrude radially outward from the guide groove 71 provided in the side wall of the one nozzle portion 10 of the shroud 30 and the rotating cylinder 13 . and a fitting pin 72 (pin portion) that is movably inserted into the housing. As shown in FIG. 1, the guide groove 71 is formed as a long hole elongated in a direction substantially orthogonal to the axial direction. Further, as shown in FIGS. 1 and 3A, the guide groove 71 is arranged below the nozzle hole 11 with respect to the rotary cylinder 13 . Hereinafter, of both ends 71a and 71b of the guide groove 71, the end farther from the nozzle portion 10 is referred to as a first end 71a, and the end closer to the nozzle portion 10 is referred to as a second end 71b.

The fitting pin 72 has an elongated round bar portion 72a and a head portion 72b provided at the tip of the round bar portion 72a. The head portion 72b is formed in a disk shape with a larger diameter than the round bar portion 72a. Further, the head portion 72b is configured to have a diameter larger than the groove width of the guide groove 71. As shown in FIG. With the round bar portion 72 a inserted into the guide groove 71 , the head portion 72 b is arranged outside the guide groove 71 to prevent the fitting pin 72 from slipping out of the guide groove 71 . Further, as shown in FIGS. 3(a) and 3(b), the head portion 72b of the fitting pin 72 is arranged not to protrude outside the side wall of the ejector body 20. As shown in FIG.

Next, locking and unlocking operations by the nozzle lock mechanism 40 and the lever lock mechanism 50 in the trigger type ejector 100 will be described. At the first position shown in FIGS. 1, 3A, and 4A, the nozzle portion 10 is covered by the ceiling wall 31 and the nozzle portion side walls 32 of the shroud 30, as described above. At this time, the fitting pin 72 is positioned at the first end portion 71 a of the guide groove 71 . At the first position, the nozzle lock mechanism 40 closes the contents pumping channel. At the first position, the contact piece 51 is in contact with or close to the operating lever 21, so that the operating lever 21 cannot be towed by the lever lock mechanism 50, and the operating lever 21 cannot be moved rearward. Rocking is regulated. Thus, in the first position, it is in the locked state as described above.

In the first position, when the nozzle portion 10 side of the shroud 30 is pushed upward, the shroud 30 rotates about the rotation shaft 25, and the second position shown in FIGS. position. At this time, the guide groove 71 also moves upward in an arc about the rotation shaft 25 . When the guide groove 71 moves, the fitting pin 72 is pushed upward together with the guide groove 71 and relatively moves within the guide groove 71 from the first end portion 71a toward the second end portion 71b. Here, the fitting pin 72 is provided on the outer peripheral surface of the rotating cylinder 13 . Therefore, the rotating cylinder 13 rotates as the fitting pin 72 moves upward. By the time the fitting pin 72 moves to the second end portion 71b of the guide groove 71, the rotating cylinder 13 rotates by a predetermined amount, and the rotation of the shroud 30 stops. At this time, the shroud 30 is at the second position, and the nozzle hole 11 and the contents pumping channel are opened by the nozzle lock mechanism 40 . Further, as described above, at the second position, the operation lever 21 is displaced to a position where it does not contact even if it swings backward, and the operation lever 21 can be pulled. Thus, at the second position, the lock is released as described above.

Next, when the shroud 30 is pushed down toward the nozzle portion 10 side at the second position, the shroud 30 rotates around the rotation shaft 25 . At this time, the guide groove 71 moves downward in an arc about the rotation shaft 25 . Along with this, the fitting pin 72 also moves downward and relatively moves in the guide groove 71 from the second end portion 71b toward the first end portion 71a. As the fitting pin 72 moves downward, the rotating cylinder 13 rotates. When the top wall 31 of the shroud 30 abuts against the nozzle portion 10, the shroud 30 cannot be pushed down further, and the rotation of the shroud 30 stops. At this time, the shroud 30 is at the first position, and both the nozzle lock mechanism 40 and the lever lock mechanism 50 are locked.

According to the trigger-type ejector 100 of the first embodiment described above, the displacing operation of the shroud 30 can be converted by the link mechanism 70 into the opening/closing operation of the contents pumping flow path by the nozzle lock mechanism 40 . Further, according to the first embodiment, the displacement operation of the shroud 30 enables or disables the pulling operation of the operating lever 21 by the lever lock mechanism 50 . That is, according to the above-described first embodiment, a simple operation of displacing the shroud 30 can switch between the locked state and the unlocked state by the two types of lock mechanisms, the nozzle lock mechanism 40 and the lever lock mechanism 50. can be done.

Also, the shroud 30 can be configured as a large part compared to the nozzle portion 10 . Therefore, as compared with the operation of rotating the nozzle portion 10, a large area that can be gripped when displacing the shroud 30 can be ensured, and the operability is improved. Furthermore, in the above-described first embodiment, the shroud 30 is rotatably attached to the ejector body 20, so that the shroud 30 can be moved from the first position to the second position by pushing up the nozzle portion 10 side of the shroud 30. The shroud 30 can be displaced from the second position to the first position by pushing down the shroud 30 toward the nozzle portion 10 side. As compared with rotating operation of the nozzle part 10, the shroud 30 can be pushed up or down, so the operability is extremely good.

By the way, in the conventional trigger-type ejection container, the nozzle lock mechanism 40 and the like were switched between the locked state and the unlocked state by directly touching the nozzle portion 10 with a hand to rotate the rotating cylinder 13. . If the nozzle portion 10 is directly rotated by hand, the contents remaining in the nozzle hole 11 may stick to the user's hands. 40 and the like may be stored in a storage box or the like without being locked. On the other hand, in the trigger-type ejector 100 of the above embodiment, the shroud 30 is pushed up to the second position when the nozzle lock mechanism 40 and the like are in the unlocked state. It is preferable that the shroud 30 is pushed down to the first position when it is housed in a container or the like, because it saves space in the axial direction. Therefore, with the trigger-type ejector 100 of the above-described embodiment, the user can be motivated to push down the shroud 30 when storing it in a container or the like. Therefore, according to the trigger-type ejector 100 of the above-described embodiment, it is possible to prevent the ejector from being stored in the storage or the like in the unlocked state. It is possible to prevent the contents from spouting out.

Further, in the conventional trigger-type ejector, an operation piece is provided so as to protrude radially outward from the rotating cylinder 13 of the nozzle portion 10, and the nozzle portion 10 can be rotated by the operation piece. There is one in which the lock mechanism 40 or the like can be switched between a locked state and an unlocked state. However, such an operating piece is provided so as to protrude outside the shroud 30 . As a result, the operation piece may get caught on another object during use or storage, and the nozzle portion 10 may rotate, thereby unintentionally switching between the locked state and the unlocked state.
On the other hand, in the above-described embodiment, the fitting pin 72 is provided so as to protrude radially outward with respect to the rotary cylinder 13 , but the head portion 72 b thereof protrudes outward from the ejector main body side wall 33 of the shroud 30 . I'm trying not to. Therefore, it is possible to prevent the locking state and the unlocking state from being unintentionally switched between the locked state and the unlocked state without the fitting pin 72 being caught by other objects or the like during use or storage.

[Second embodiment]
Next, a trigger-type ejector 100 of a second embodiment will be described with reference to FIGS. 5 and 6. FIG. In addition, the same code|symbol is attached|subjected about the structure similar to 1st embodiment, and the detailed description is abbreviate|omitted. As shown in FIG. 5(b), the trigger-type ejector 200 of the second embodiment includes a nozzle portion 10, an ejector main body 20, etc., similarly to the trigger-type ejector 100 of the first embodiment. It is detachably attached to the container body 1 via the attachment cap 60 . An operating lever 21 is swingably held on the ejector main body 20 . In addition, the ejector main body 20 is provided with a cylinder cylinder 22, a plunger 23, and the like, which constitute a pump mechanism. By pulling the operation lever 21 backward, the plunger 23 reciprocates in the cylinder cylinder 22, and the contents sucked from the container main body 1 are ejected from the nozzle hole 11 by the pump action. is configured to

The nozzle lock mechanism 40 and the lever lock mechanism 50 are also provided in the trigger type ejector 200 of the second embodiment. In a second embodiment, the ejector body 20 is covered by a shroud body 80 (shroud). A nozzle cover portion 81 (cover portion) that covers the nozzle portion 10 is attached to the shroud body 80 so as to be rotatable about a rotating shaft 82 provided on the shroud body 80 . As shown in FIG. 5(b), the nozzle cover portion 81 is narrower than the shroud body 80 in width. The nozzle cover portion 81 is provided with a contact piece 51 that constitutes the lever lock mechanism 50, as in the first embodiment. A guide groove 71 is provided in the nozzle cover portion 81 as in the first embodiment, and a fitting pin 72 is movably inserted into the guide groove 71 . The head portion 72 b of the fitting pin 72 is arranged outside the guide groove 71 , but is arranged so as not to protrude outside the shroud body 80 .

In the second embodiment, by rotating the nozzle cover portion 81 with respect to the shroud body 80, the nozzle cover portion 81 is positioned between the first position shown in FIG. 5B and the second position shown in FIG. is displaced between Then, the displacing motion of the nozzle cover portion 81 is converted into the rotating motion of the rotating cylinder 13 by the link mechanism 70, and the locked state and the unlocked state by the nozzle lock mechanism 40 and the lever lock mechanism 50 are obtained in the same manner as in the first embodiment. state is switched.

Further, in the second embodiment, as shown in FIG. 5A, the ceiling wall surface of the nozzle cover portion 81 is provided with a notch portion 81a that opens toward the ejection surface 12 side. If the peripheral wall of the rotating barrel 13 is printed to indicate the locked state of each locking mechanism such as "extended", "open", "stopped" or "closed", the rotating barrel can be opened from the notch 81a. 13 peripheral walls are visible. In the trigger-type ejector 200 as well, if such printing is performed on the peripheral wall of the rotary cylinder 13, the contents of the printing can be confirmed from the notch 81a, and it is possible to determine whether or not the contents can be ejected at present. Easier to verify. Further, by providing the notch 81a, the tip of the nozzle part 10 can be easily seen during operation, making it easier to eject the contents toward the target position.

The trigger-type ejector 200 of the second embodiment includes two parts, a shroud body 80 and a nozzle cover portion 81, which correspond to the shroud 30 in the trigger-type ejector 100 of the first embodiment. However, the configuration differs in that only the nozzle cover portion 81 is displaced instead of displacing the entire shroud 30, but the other configurations are substantially the same as described in the first embodiment. Approximately the same effects can be obtained.

The trigger-type ejector 100 of the first embodiment and the trigger-type ejector 200 of the second embodiment described above are merely one aspect of the present invention, and the trigger-type ejector according to the present invention is the gist of the present invention. , and each configuration of the nozzle portion 10, the ejector main body 20, the nozzle lock mechanism 40, the lever lock mechanism 50, etc. is not limited to the configuration described in the above embodiment, Various configurations including conventionally known configurations can be employed as long as they have similar functions.

For example, the nozzle part 10 can appropriately change the configuration so as to eject the contents in various forms such as spraying, jetting, and foaming. In addition, by appropriately changing the configurations of the nozzle portion 10 and the nozzle lock mechanism 40, the ejection mode of the contents can be changed to, for example, "spray"/"spray"/"stop" depending on the amount of rotation of the nozzle portion 10. It may be configured to be switchable. Note that “stopped” indicates a locked state by the nozzle lock mechanism 40 .

The ejector main body 20 is also provided with an operation lever 21 that is pivotable in the front-rear direction and a pump mechanism. The configuration is not particularly limited as long as it has a function of pumping the contents sucked from the container main body 1 to the nozzle portion 10 side.

Regarding the nozzle lock mechanism 40, in the above-described embodiment, the connecting cylinder (not shown) is provided with the first flow path, the second flow path, and the switching means, and the first flow path and the second flow path are switched according to the rotation position of the rotating cylinder 13. Although communication and disconnection with the path are switched, it is not limited to such a configuration. For example, depending on the rotational position of the rotational cylinder 13, the valve element or the like may be pressed against or separated from the nozzle hole 11, thereby opening and closing the content pumping channel. Alternatively, the contents pumping flow path may be opened and closed without rotating the rotating cylinder 13 . For example, a shielding plate may be provided in the contents pressure-feeding channel, and the contents pressure-feeding channel may be opened and closed by moving the position of the shielding plate according to the displacement operation of the shroud 30 or the nozzle cover part 81. . The configuration of the nozzle lock mechanism 40 is not particularly limited. Various configurations can be similarly adopted for the lever lock mechanism 50 .

In addition, in the trigger-type ejector 100 according to the present invention, the lever lock mechanism 50 is not an essential component. The locked state and the unlocked state may be switched, and the lever lock mechanism 50 may be switched between the locked state and the unlocked state by another method.

Furthermore, the shroud 30 and the nozzle cover portion 81 may be configured as cover portions that cover at least a portion of the nozzle portion 10, and their specific shapes are not limited to the illustrated examples, and may be changed as appropriate. can do. In the above embodiment, the shroud 30 and the nozzle cover portion 81 are rotated to displace them vertically in the axial direction, but the displacement operation of the shroud 30 and the nozzle cover portion 81 is limited to this. not a thing
For example, the shroud 30 and the nozzle cover portion 81 can be displaced only in a direction substantially perpendicular to the axial direction, and the shroud 30 and the nozzle cover portion 81 can be moved rearward from the first position where the shroud 30 and the nozzle cover portion 81 cover the nozzle portion 10 . The shroud 30 and the nozzle cover portion 81 may be displaced to the second position separated from the nozzle portion 10 by a predetermined distance by sliding the shroud 30 and the nozzle cover portion 81 to the second position. At this time, by providing the guide groove 71 with a predetermined inclination angle with respect to the axial direction, the displacement motion of the shroud 30 and the nozzle cover portion 81 is converted into the rotation motion of the rotary cylinder 13, and the nozzle lock mechanism 40, etc. may be switched between the locked state and the unlocked state.
