PURPOSE:To achieve miniaturization of a solenoid coil and noise reduction simultaneously. CONSTITUTION:A stopper plate 13, having a through hole 13a into which a lock plate 11 moved in the direction of arrow Y by control of a detent knob can move and a mount 1b adjoining to the through hole, can reciprocate between a lock position in which the mount 13b is opposed to the lock plate 11 and an unlock position in which the through hole 13a is opposed to the lock plate 11, and is normally pressed toward the unlock position by a first compression coil spring 14. A cam member 17 connected to the stopper plate 13 via a second compression coil spring 18 having a greater force than that of the compression coil spring 14, is exerted with a force of movement in the direction of the unlock position by cam action between it and the lock plate 11. The resilient force of the compression coil spring 18 is set to be smaller than the resultant of the force of a solenoid coil 15 to hold a plunger and the resilient force of the compression coil spring 14.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle lock device which can be used as a shift lock device of an automobile.

[0002]

2. Description of the Related Art A shift lock device provided in an automobile is generally constructed so that the automatic transmission cannot be operated from a parking position to another position when a foot brake is depressed when the automobile is started. 28 and 29 show an example of the configuration of the main part of such a shift lock device.

That is, in FIGS. 28 and 29, the lock plate 1 is moved in the direction of arrow A in FIG. 28 when a detent knob provided on a shift lever (not shown) for switching a shift position is pressed. It is always urged and held at the position shown in FIG. Stopper 3 supported by fixed plate 2 via shaft 2a
Is at a lock position where one end portion prevents the lock plate 1 from moving in the direction of arrow A (shown by the solid line in FIG. 29).
And an unlock position (indicated by a chain double-dashed line in FIG. 29) that allows the lock plate 1 to move.

The other end of the stopper 3 is rotatably connected to the plunger 4a of the electromagnetic solenoid 4, and when the electromagnetic solenoid 4 is energized, the stopper 3 is moved to the unlock position. It Further, the electromagnetic solenoid 4 is provided with a return compression coil spring 5, and the spring force of the return compression coil spring 5 holds the stopper 3 in the locked position when the electromagnetic solenoid 4 is in a disconnected state. . The electromagnetic solenoid 4 is normally de-energized, and is configured to be energized only when the accessory circuit of the automobile is formed and the foot brake is depressed while the automatic transmission is in the parking position.

Therefore, when the electromagnetic solenoid 4 is in the disconnected state, the stopper 3 is held in the locked position by the spring force of the restoring compression coil spring 5, so that the movement of the lock plate 1 in the direction of the arrow A is prevented and the detent. The pin pressing operation is invalidated. Further, when the electromagnetic solenoid 4 is energized, the stopper 3 is rotated to the unlocked position by the electromagnetic solenoid 4, so that the lock plate 1 is allowed to move in the direction of arrow A and the detent pin pressing operation is enabled. To be done.

[0006]

In the above-mentioned conventional structure, since the return compression coil spring 5 is provided, when the stopper 3 is moved from the lock position to the unlock position, the electromagnetic solenoid 4 returns to the return position. The suction operation must be performed against the spring force of the compression coil spring 5.
Therefore, it is necessary to make the generated force of the electromagnetic solenoid 4 relatively large, and it is inevitable that the electromagnetic solenoid 4 becomes large in size. Therefore, when the electromagnetic solenoid 4 is incorporated into the shift lever, there are many restrictions on the space. It caused the problem of. Further, when the electromagnetic solenoid 4 is energized, operating noise is generated due to movement of the plunger, which causes a problem of increased noise.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a vehicle lock device which has effects such as reduction in size of an electromagnetic solenoid and suppression of noise at the same time.

[0008]

In order to achieve the above-mentioned object, the present invention provides a vehicle locking device for selectively invalidating the operation of an operating member so as to interlock with the operating member. An interlocking member that is provided and that moves in a predetermined operating direction in response to the operation, a lock position that abuts the interlocking member when the interlocking member is moved in the operating direction, and prohibits its movement, and the movement of the interlocking member. It has a stopper member that can reciprocate between an unlock position that allows it to retreat from the locus and allow its movement, and a plunger that is connected to this stopper member, and holds the stopper member in the unlock position in the energized state. An electromagnetic solenoid, a first spring means for constantly urging the stopper member in the unlock position direction, and a size larger than the first spring means with respect to the stopper member. It is connected through a second spring means having a spring force, and a moving force in the lock position direction is applied to the stopper member in response to the movement of the interlocking member in the actuating direction through the second spring means. A driven member to be applied, and a spring force of the second spring means is set to a value smaller than a resultant force of the plunger holding force of the electromagnetic solenoid and the spring force of the first spring means. (Claim 1).

In this case, when the interlocking member is moved in the actuating direction, the moving force of the follower member in the locking position direction with respect to the stopper member is caused by a cam action corresponding to the contact with the interlocking member. Can also be constituted by a cam member that applies the second spring means (claim 2).

Further, in the vehicle lock device for selectively invalidating the operation of the operating member, the interlocking member which moves in a predetermined operating direction in conjunction with the operation of the operating member, and the interlocking member actuates the operating member. A stopper member capable of reciprocating between a lock position that abuts the interlocking member and prohibits its movement when moved in a direction, and an unlock position that retreats from the movement trajectory of the interlocking member and allows its movement. An electromagnetic solenoid having a plunger connected to the stopper member for holding the stopper member in the unlocked position in an energized state, and a stopper member for constantly pressing the stopper member by the spring force of the driven member spring means. While holding the member in the unlocked position, the member is moved to the position where the pressing of the stopper member is released according to the movement of the interlocking member in the operating direction. The stopper member is provided with a driven member that is moved to allow the stopper member to move in the lock position direction, and a stopper member spring means that constantly urges the stopper member in the lock position direction. The spring force of the spring means for use may be set to a value smaller than the spring force of the spring means for the driven member and the plunger holding force of the electromagnetic solenoid, respectively (claim 3).

In this case, the driven member may be a cam member which is displaced by a cam action corresponding to the contact with the interlocking member when the interlocking member is moved in the operating direction (claim). Item 4).

[0012]

In the vehicle lock device according to the first aspect of the present invention, the stopper member is always urged toward the unlock position by the first spring means, regardless of whether the electromagnetic solenoid is in the on / off state. You will be in the unlocked position. When the operating member is operated, the driven member applies a moving force in the lock position direction to the stopper member through the second spring means in response to the movement of the interlocking member in the operating direction. Become.

When the electromagnetic solenoid is cut off during this operation, the force for holding the stopper member in the unlocked position is only the spring force by the first spring means, but the spring force is the stopper member. Since the state is smaller than the spring force of the second spring means for transmitting the moving force between the driven member and the driven member, the stopper member serves as the first spring means in response to the operation of the operation member as described above. It will be moved toward the lock position. Therefore, since the interlocking member and the stopper member come into contact with each other and the movement of the interlocking member is prohibited, the operation of the operating member is invalidated.

On the other hand, when the electromagnetic solenoid is energized when the operating member is operated, the force for holding the stopper member at the unlocked position is the plunger holding force by the electromagnetic solenoid and the first spring means. It is the resultant force with the spring force. In this case, the spring force of the second spring means is
Since the value is set smaller than the resultant force, when the moving force in the lock position direction is applied to the stopper member through the second spring means in response to the operation of the operating member,
Only the driven member is moved according to the deformation of the second spring means, and the stopper member remains held in the unlocked position. Therefore, the stopper member keeps a state of being retracted from the movement locus of the interlocking member, and the movement of the interlocking member in the operating direction is permitted, so that the operation of the operating member is enabled. become.

In this case, the electromagnetic solenoid is required only to hold the stopper member in the unlocked position at all times in the unlocked position, and no large force is required, so that the electromagnetic solenoid can be downsized. become. Moreover, since the plunger is not moved when the electromagnetic solenoid is energized, no operating noise is generated due to the movement, and it is possible to prevent an increase in noise.

According to another aspect of the vehicle lock device of the present invention, when the operating member is operated, a cam action is generated according to the contact between the interlocking member moved in the operating direction by the operating member and the driven member configured as the cam member. As a result, a moving force in the lock position direction is applied to the stopper member through the second spring means, and the moving force is reliably transmitted.

According to another aspect of the vehicle lock device of the present invention, the spring force of the stopper member spring means for urging the stopper member in the lock position direction causes the spring force to act on the driven member. Since it is set to a value smaller than the spring force of the means, the driven member normally presses the stopper member by the spring force of the driven member spring means to hold the stopper member in the unlocked position.
When the operating member is operated, the driven member is displaced to the position where the pressing of the stopper member is released in response to the movement of the interlocking member in the actuating direction, and in the locking position direction of the stopper member. Will be allowed to move.

If the electromagnetic solenoid is cut off during this operation, the stopper member is moved toward the lock position by the stopper member spring means, so that the interlocking member and the stopper member come into contact with each other. The movement of the interlocking member is prohibited, and the operation of the operation member is invalidated.

On the other hand, when the electromagnetic solenoid is energized when the operating member is operated, the spring force of the stopper member spring means is set to a value smaller than the plunger holding force of the electromagnetic solenoid. , The driven member is displaced in the same manner as described above according to the operation of the operation member,
Even when the stopper member is allowed to move in the lock position direction, the stopper member remains held at the unlock position by the plunger holding force. Therefore, the stopper member keeps a state of being retracted from the movement locus of the interlocking member, and the movement of the interlocking member in the operating direction is permitted, so that the operation of the operating member is enabled. become.

Also in this case, the electromagnetic solenoid is
Since the stopper member that is normally in the unlocked position need only be held in the unlocked position, and a large force is not required, downsizing can be realized and the electromagnetic solenoid is moved. Since the operation noise is not generated, it is possible to prevent the noise from increasing.

According to another aspect of the vehicle lock device of the present invention, the driven member is a cam member which is displaced by a cam action corresponding to the contact with the interlocking member which is moved in the operating direction by the operation of the operating member. Therefore, the transmission of the moving force from the interlocking member to the driven member can be reliably performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment in which the present invention is applied to an automobile shift lock device will be described below with reference to FIGS. 1 to 3, the lock plate 11 as an interlocking member is provided so as to be movable in the longitudinal direction (vertical direction in FIGS. 1 and 3), and has a shift lever for an automatic transmission (not shown). When a detent knob (corresponding to an operating member in the present invention) having a well-known configuration is pressed, the detent knob is moved in the direction of operation, which is the arrow Y direction in FIGS. 1 and 3. The case 12 having a rectangular shape is fixed to an appropriate stationary portion, and the lock plate 11 is provided on the upper surface of the central portion thereof.
Is provided with a guide hole 12a.

Stopper plate 1 as a stopper member
3 is provided in the case 12 so as to be movable in a direction orthogonal to the moving direction of the lock plate 11. Specifically, the stopper plate 13 has a through hole 13 a through which the lock plate 11 can enter from the tip portion, and the through hole 13 a.
A trapezoidal portion 13b adjacent to a is formed, and the stopper plate 13 has a lock position (see FIG. 1B) in which the trapezoidal portion 13b is opposed to the tip of the lock plate 11 from below. , The unlocked position where the trapezoidal portion 13b is retracted from the movement path of the tip of the lock plate 11, that is, the unlocked position where the through hole 13a faces the tip of the lock plate 11 from below (see FIG. 1).
(A), (c), see FIG. 2). The stopper plate 13 is configured to include a leg portion 13c that is in sliding contact with the bottom surface of the case 12, and a guide pin 13d that projects in the moving direction. The guide pin 13d stands on the bottom portion of the case 12. The rib 12b is inserted through the guide hole 12c.

A first compression coil spring 14 is provided around the guide pin 13d so that a spring force in the extending direction is applied between the rib 12b and the stopper plate 13.
(Corresponding to the first spring means in the invention according to claim 1) is wound, whereby the stopper plate 13 is always in the unlock position direction (arrow X in FIG. 1A).
Direction).

An end of the stopper plate 13 opposite to the guide pin 13d is connected to a plunger 15a of an electromagnetic solenoid 15 housed in the case 12 via a pin 16. The electromagnetic solenoid 15 holds the state where the plunger 15a is attracted to the core (not shown) when energized, and the stopper plate 13 is held at the unlocked position accordingly. The electromagnetic solenoid 15 is configured to be energized only when the accessory circuit of the vehicle is formed and the foot brake is operated while the automatic transmission is in the parking position.

A rising wall 13e is provided upright at an end of the stopper plate 13 opposite to the trapezoidal portion 13b, and the trapezoidal portion 1 is provided on the stopper plate 13.
A cam member 17 as a driven member that is movable between 3b and the rising wall 13e is provided in a mounted state. The cam member 17 has a through hole 1 on the stopper plate 13 side.
The lock plate 11 is in a position where it covers 3a.
Is provided with a cam surface 17a facing the tip (lower end) of the lock plate 11, and when the lock plate 11 is moved in the direction of the arrow Y, the cam surface 17a reacts with the cam action according to the contact of the tip with the cam surface 17a. The moving force in the arrow X direction is applied.

The cam member 17 has a connecting pin 17b protruding in the direction opposite to the cam surface 17a, and the connecting pin 17b is locked by the lock plate 13.
It is inserted into a through hole 13f formed in the rising wall 13e on the side. A second compression coil spring 18 (the second compression coil spring 18 according to the invention of claim 1) is configured such that a spring force in an extension direction is applied between the rising wall 13e and the cam member 17 around the connecting pin 17b. (Corresponding to spring means) is wound. As a result, the cam member 17 is in a state of being connected to the stopper plate 13 via the second compression coil spring 18, and is normally attached in the position direction covering the through hole 13a on the stopper plate 13 side. It is energized.

In this case, the second compression coil spring 18
Has a larger spring force than the first compression coil spring 14, and the spring force is the holding force of the plunger 15a by the electromagnetic solenoid 15 and the spring force of the first compression coil spring 14. It is set to be smaller than the total force of.

As shown in FIG. 3, the cam member 17 is provided with ridges 17c, 17c on both sides of its lower edge, and these ridges 17c are formed in the guide groove on the stopper plate 13 side. Is in a state of being engaged with.

The cancel lever 19 provided in the case 12 contacts the rising wall 13e in a state where the stopper plate 13 is in the unlocked position and prohibits the stopper plate 13 from moving in the opposite X direction. Reciprocating movement between the operation position (shown by a chain double-dashed line in FIG. 1 (c)) and an operation stop position (see solid lines in FIGS. 1 (a), (b), and (c)) above the operation position. It is configured to move, and is normally held at the operation stop position by the torsion coil spring 20. Further, a cancel pin 21 is inserted into a through hole 12d formed in the upper surface of the case 12, and the cancel lever 19 can be rotated to an operating position by pushing down the cancel pin 21.

Next, the operation of the above configuration will be described. Since the stopper plate 13 is normally urged in the unlock position direction by the first compression coil spring 14, it is moved to the unlock position regardless of whether the electromagnetic solenoid 15 is turned on or off. Also, the cam member 1
7 is located at a position where the cam surface 17a faces the tip of the lock plate 11 (state of FIG. 1A).

From this state, when the lock plate 11 is moved in the operating direction (direction of arrow Y) in response to the pressing operation of the detent knob (not shown), the lock plate 11
By the cam action corresponding to the contact between the tip of the cam member 17 and the cam surface 17a of the cam member 17, the moving force in the direction opposite to the arrow X is given to the cam member 17, and the moving force is applied to the stopper plate 13. On the other hand, it is applied through the second compression coil spring 18.

When the electromagnetic solenoid 15 is cut off during the pressing operation of the detent knob, the force for holding the stopper plate 13 in the unlocked position is the spring force of the first compression coil spring 14. However, the spring force of the stopper plate 13 and the cam member 1 is
Second compression coil spring 18 for transmitting moving force to and from
Since the spring force is smaller than the spring force, the stopper plate 13 moves in the lock position direction (counter arrow X direction) from the unlock position against the first compression coil spring 14 in response to the pressing operation of the detent knob as described above. Will be done.

When the stopper plate 13 is moved to the lock position in this manner, the tip of the lock plate 11 comes into contact with the base 13b of the stopper plate 13 as shown in FIG. 1 (b). Then, since the movement of the lock plate 11 is prohibited, further pressing operation of the detent knob is invalidated.

On the other hand, when the electromagnetic solenoid 15 is energized when the detent knob is pressed, the electromagnetic solenoid 15 attracts and holds the plunger 15a. In this state, the force that holds the stopper plate 13 in the unlocked position is the resultant force of the holding force of the plunger 15a by the electromagnetic solenoid 15 and the spring force of the first compression coil spring 14. In this case, since the spring force of the second compression coil spring 18 is set to a value smaller than the resultant force, the moving force in the lock position direction with respect to the stopper plate 13 is set to the cam member 17 in response to the pressing operation of the detent knob. And when applied through the second compression coil spring 18, as shown in FIG.
According to the compressive deformation of the compression coil spring 18, the cam member 1
Only 7 is moved, and the stopper plate 13 remains held in the unlock position direction. For this reason, the through hole 13a of the stopper plate 13 comes to face the tip portion of the lock plate 11, and the lock plate 11
Will enter into the through hole 13a, so that the movement of the lock plate 11 in the direction of the arrow Y is allowed and the depressing operation of the detent knob is validated.

The electromagnetic solenoid 1 may be used for some reason.
When the pressing operation of the detent knob is enabled in a state where the power cannot be supplied to the detent knob 5, the pressing operation of the detent knob may be performed while the cancel pin 21 is pressed down. That is, when the cancel pin 21 is pushed down, the cancel lever 19 is rotated to the operating position to hold the stopper plate 13 in the unlock position, so that the pressing operation of the detent knob is enabled.

According to the above-described structure of the present embodiment, the electromagnetic solenoid 15 only needs to hold the stopper plate 13 which is normally held at the unlocked position at the unlocked position. Since it is not necessary to perform the suction operation against the spring force, a large force is not required, and therefore, the size reduction can be realized. Moreover, since the plunger 15a does not move when the electromagnetic solenoid 15 is energized, no operating noise is generated due to the movement, and it is possible to prevent an increase in noise. Also, the lock plate 1
Since the cam action of the cam member 17 is used to transmit the moving force between the 1 and the stopper plate 13, the moving force can be surely transmitted.

FIG. 4 and FIG. 5 show the essential parts of the second embodiment of the present invention, which has the same effects as those of the first embodiment, and only the parts different from the first embodiment will be described below. . That is, in this embodiment, the spindle 2 is used as a stopper member instead of the stopper plate 13 in the first embodiment.
A stopper plate 23 that rotates about 2 as a fulcrum is provided, and the stopper plate 23 and the electromagnetic solenoid 15 are provided.
The pin 24 is connected to the plunger 15a.
The stopper plate 23 has a through hole 23a through which the lock plate 11 can enter from the tip, and the through hole 23a.
And the trapezoidal portion 23b adjacent to the trapezoidal portion 2b.
The lock position in which 3b is opposed to the tip of the lock plate 11 from below and the through hole 23a is set in the lock plate 1.
It is configured such that it can be reciprocally rotated between an unlocked position that is opposed to the tip of the first member from below.

At the base end of the stopper plate 23,
A torsion coil spring 25 (corresponding to the first spring means in the invention of claim 1) for constantly urging this in the unlock position direction is wound, and the spring force of the torsion coil spring 25. Is smaller than the spring force of the compression coil spring 18 interposed between the cam member 17 and the rising wall 23c formed on the stopper plate 23, and the resultant force of the spring force and the holding force of the plunger 15a by the electromagnetic solenoid 15. Is set to be larger than the spring force of the compression coil spring 18.

Therefore, even in such a structure, the stopper plate 23 is always provided with the torsion coil spring 2
Since it is urged toward the unlock position by means of No. 5, it is moved to the unlock position regardless of the electric connection / disconnection state of the electromagnetic solenoid 15, and the cam member 17 moves its cam surface 17a to the lock plate. Since the detent knob is located at a position opposed to the tip of the detent knob 11, the detent knob pressing operation can be validated or invalidated in accordance with the on / off state of the electromagnetic solenoid 15 as in the first embodiment. is there.

FIG. 6 and FIG. 7 show the essential parts of a third embodiment of the present invention which has the same effects as the first embodiment, and only the parts that differ from the first embodiment will be described below. . That is, the stopper plate 2 as a stopper member
6 and a cam plate 27 as a driven member are provided rotatably in the directions of arrow Z and counter arrow Z in FIG. 6 via the same support shaft 28.

The stopper plate 26 has a tip surface 26.
The lock position where a is opposed to the tip of the lock plate 11 from below (see the chain double-dashed line in FIG. 6), and the tip surface 26a
Is configured to be reciprocally movable to and from the unlock position (see the solid line in FIG. 6) retracted from the movement path of the lock plate 11, and the plunger 15a of the electromagnetic solenoid 15 is movable.
To a pin 29. In this case, the first torsion coil spring 3 that constantly urges the stopper plate 26 in the unlock position direction (arrow Z direction) is provided at the stopper plate 26 side portion of the support shaft 28.
0 (corresponding to the first spring means in the invention of claim 1)
Is wrapped around.

Further, the cam plate 27 on the support shaft 28
A second torsion coil spring 31 corresponding to the second spring means according to the invention of claim 1 is wound around the side portion, and one end of the torsion coil spring 31 is connected to the cam plate 27. The other end is connected to the stopper plate 26. As a result, the cam plate 27 is in a state of being connected to the stopper plate 26 via the second torsion coil spring 31, and the cam surface 27a at the tip end portion of the lock plate 11 is always in contact with the stopper plate 26. It is biased and held at a position opposed to. in this case,
The second torsion coil spring 31 has a larger spring force than the first torsion coil spring 30, and the spring force is the holding force of the plunger 15a by the electromagnetic solenoid 15 and the first torsion coil. It is set to be smaller than the resultant force of the spring 30 and the spring force.

According to the present embodiment configured as described above,
Since the stopper plate 26 is normally urged in the unlock position direction by the first torsion coil spring 30, the stopper plate 26 is held in the unlock position regardless of whether the electromagnetic solenoid 15 is electrically connected or disconnected. From this state, when the lock plate 11 is moved in the arrow Y direction in response to the pressing operation of the detent knob (not shown), the cam corresponding to the contact between the tip portion of the lock plate 11 and the cam surface 27a of the cam plate 27. By the action, the moving force in the direction opposite to the arrow Z is applied to the cam plate 27, and the moving force is applied to the stopper plate 26 through the second torsion coil spring 31.

When the electromagnetic solenoid 15 is cut off during the pressing operation of the detent knob, the force for holding the stopper plate 26 in the unlocked position is the spring force of the first torsion coil spring 30. However, since the spring force is smaller than the spring force of the second torsion coil spring 31, the stopper plate 26 causes the first torsion coil spring 30 to move in response to the pressing operation of the detent knob as described above. Against this, it is moved from the unlock position to the lock position direction (counter arrow Z direction).

When the stopper plate 26 is moved to the lock position in this way, the tip of the lock plate 11 comes into contact with the tip surface 26a of the stopper plate 26, and the movement of the lock plate 11 is prohibited. Therefore, the pressing operation of the detent knob is invalidated.

On the other hand, when the electromagnetic solenoid 15 is energized when the detent knob is pressed, the electromagnetic solenoid 15 attracts and holds the plunger 15a. In this state, the force that holds the stopper plate 26 in the unlocked position is the resultant force of the holding force of the plunger 15a by the electromagnetic solenoid 15 and the spring force of the first torsion coil spring 30. in this case,
Since the spring force of the second torsion coil spring 31 is set to a value smaller than the resultant force, when the moving force in the lock position direction is applied to the stopper plate 26 in response to the pressing operation of the detent knob, Only the cam plate 27 is moved in the direction opposite to the arrow Z in response to the expansion deformation of the torsion coil spring 31, and the stopper plate 26 remains held at the unlock position. Therefore, the front end surface 26a of the stopper plate 26 is retracted from the movement path of the lock plate 11, and the movement of the lock plate 11 in the arrow Y direction is allowed, so that the pressing operation of the detent knob is validated. Will be.

FIG. 8 and FIG. 9 show the essential parts of a fourth embodiment of the present invention which achieves the same effects as the first embodiment, and only the parts that differ from the first embodiment will be described below. . That is, the slider 32 as the driven member is movably mounted on the stopper plate 13 'having a shape similar to that of the stopper plate 13 in the first embodiment between the trapezoidal portion 13b' and the rising wall 13e '. There is. The lock plate 33 as the interlocking member is configured to be moved in the direction of the arrow Y, which is the operating direction, when the detent knob is pressed, and the main body corresponding to the through hole 13a 'of the stopper plate 13'. It has a portion 33a and an auxiliary arm 33b branched from the main body portion 33a.

The trip arm 35 rotatably provided with the support shaft 34 as a fulcrum is rotated by being pressed by the auxiliary arm 33b when the lock plate 33 is moved in the arrow Y direction. The slider 32 is configured to move in the opposite arrow X direction in response to the rotation.

The stopper plate 13 'is connected to the plunger 15a of the electromagnetic solenoid 15 via the pin 16, and the compression coil spring 1 is always provided.
4, the slider 32 is in a state of being connected to the stopper plate 13 ′ via the compression coil spring 18.

Therefore, also in the present embodiment having such a configuration, as in the first embodiment, when the lock plate 33 is moved in the direction of the arrow Y by the pressing operation of the detent knob, the electromagnetic solenoid 15 is turned off. In this case, the stopper plate 13 'is moved to the lock position, and is kept held in the unlock position when the electromagnetic solenoid 15 is energized.
The electromagnetic solenoid 15 is validated or invalidated according to the on / off state of the electromagnetic solenoid 15.

FIG. 10 shows a fifth embodiment of the present invention, and only the parts different from the first embodiment will be described below. Stopper plate 3 as a stopper member
6 is provided in a case 12 'so as to be movable in a direction orthogonal to the moving direction of the lock plate 11, and an arm portion 36a projecting at one end thereof also serving as a spring receiving seat has a plunger of the electromagnetic solenoid 15'. Pin 1 for 15a '
It is connected via 6. This stopper plate 36
Is formed in a frame shape having a through hole 36b into which the lock plate 11 can be inserted from the tip, and is provided with a trapezoidal portion 36c adjacent to the through hole 36b from the electromagnetic solenoid 15 'side.

In this case, the stopper plate 36 is
The lock position (see FIG. 10B) in which the trapezoidal portion 36c is opposed to the tip end portion of the lock plate 11 from below and the unlock position in which the trapezoidal portion 36c is retracted from the movement trajectory of the tip end portion of the lock plate 11 Position, that is, the through hole 36b
Is reciprocally movable between an unlock position (FIGS. 10 (a) and 10 (c)) in which the front end of the lock plate 11 is opposed from below. The stopper plate 36
A standing wall 36d that abuts on the cancel lever 19 is erected at an end portion of the arm opposite to the arm portion 36a.

In the through hole 36b of the stopper plate 36, there is provided a cam member 37 as a driven member that is movable between the trapezoidal portion 36c and the rising wall 36d in the through hole 36b. The cam member 37 faces the tip end (lower end) of the lock plate 11 in a state in which the cam member 37 is most moved to the trapezoidal portion 36c side.
7a is provided, and when the lock plate 11 is moved in the arrow Y direction, a moving force in the opposite arrow X direction is given by a cam action in response to the tip end of the lock plate 11 coming into contact with the cam surface 37a. Has become.

The cam member 37 has a connecting pin 37b protruding in the direction opposite to the cam surface 37a, and the connecting pin 37b is formed on the rising wall integrally formed with the case 12 '. Through hole 12f of 12e
Has been inserted into. A first compression coil spring 38 is provided around the connecting pin 37b so that a spring force in the extending direction acts between the rising wall 12e and the cam member 37.
(Corresponding to the spring means for the driven member in the invention according to claim 3) is wound. As a result, the cam member 37, which receives the spring force of the first compression coil spring 38, always moves the stopper plate 36 in the unlock position direction (see FIG. 10).
It is pressed in the direction of arrow X in (a).

Plunger 1 of the electromagnetic solenoid 15 '
A second compression coil spring 39 (claim 3) is arranged such that a spring force in the extending direction is applied between the main body of the electromagnetic solenoid 15 'and the arm portion 36a of the stopper plate 36 around the periphery of 5a'. (Corresponding to the spring member for the stopper member in the invention described above) is wound around the second member.
The compression coil spring 39 always urges the topper plate 36 in the lock position direction (the direction opposite to the arrow X in FIG. 10A).

In this case, the second compression coil spring 39 is used.
Is set to a value smaller than each of the spring force of the first compression coil spring 38 and the holding force of the plunger 15a 'by the electromagnetic solenoid 15'. Therefore, the stopper plate 36 is always pressed by the cam member 37 that receives the spring force of the first compression coil spring 38 and is held at the unlock position.

Next, the operation of the above configuration will be described. The stopper plate 36 is pressed by the cam member 37 and moved to the unlocked position regardless of whether the electromagnetic solenoid 15 ′ is in the on / off state or the cam member 37.
Is located at a position where the cam surface 37a faces the tip of the lock plate 11 (state of FIG. 10A).

From this state, when the lock plate 11 is moved in the operating direction (direction of arrow Y) in response to the pressing operation of the detent knob (not shown), the tip of the lock plate 11 and the cam surface 37a of the cam member 37 are The cam member 37 is moved in the direction opposite to the arrow X direction against the spring force of the first compression coil spring 38 by the cam action according to the abutment of the cam plate 37.
6 is displaced to the position where the pressing is released, and the stopper plate 36 is allowed to move in the lock position direction (counter arrow X direction).

When the electromagnetic solenoid 15 'is cut off during the pressing operation of the detent knob, the stopper plate 36 causes the second compression coil spring 39 to move.
It is moved to the locked position by the spring force of. When the stopper plate 36 is moved to the lock position in this way, as shown in FIG. 10B, the tip end portion of the lock plate 11 comes into contact with the trapezoidal portion 36c of the stopper plate 36. Since the movement of the lock plate 11 is prohibited, further pressing operation of the detent knob is invalidated.

On the other hand, when the electromagnetic solenoid 15 'is energized when the detent knob is pressed, the electromagnetic solenoid 15' is moved to the plunger 15a '.
Will be held by adsorption. At this time, since the spring force of the second compression coil spring 39 is set to a value smaller than the holding force of the plunger 15a 'by the electromagnetic solenoid 15', the cam member 37 operates in the same manner as described above according to the operation of the detent knob. Even when the stopper plate 36 is displaced so that the stopper plate 36 is allowed to move in the lock position direction, the stopper plate 36 is retained by the holding force of the plunger 15'a as shown in FIG. 10 (c). It remains held in the unlocked position against the spring force of the second compression coil spring 39.

Therefore, the through hole 36b of the stopper plate 36 faces the tip of the lock plate 11 (that is, the stopper plate 36 is substantially retracted from the moving path of the lock plate 11), and Since the lock plate 11 comes into the through hole 36b, the movement of the lock plate 11 in the arrow Y direction is allowed, and the detent knob pressing operation is validated.

Therefore, also in the above-described structure of this embodiment, the electromagnetic solenoid 15 'is provided with the stopper plate 36 which is always held in the unlock position.
It is sufficient to hold the unlocked position against the comparatively small spring force of the compression coil spring 39, and it is not necessary to perform the suction operation against the spring force as in the conventional configuration, so that a large force is not required. Therefore, the miniaturization can be realized. Moreover, since the plunger 15a 'is not moved when the electromagnetic solenoid 15' is energized, the operating noise due to the movement is not generated and the increase of noise can be prevented. In addition, the lock plate 11 and the stopper plate 3
Since the cam action of the cam member 37 is used to transmit the moving force between the six members, it is possible to reliably transmit the moving force.

11 to 16 show a sixth embodiment of the present invention having the same effect as that of the first embodiment, and only the portions different from the first embodiment will be described below.
That is, in FIGS. 11 to 13, for example, a pair of support protrusions 40a, 40a are cut and formed on the metal stay 40, and the support shaft 41 hung between the support protrusions 40a includes: A stopper lever 42 as a stopper member and a cam lever 43 as a driven member are indicated by an arrow Z in FIG.
And is rotatably supported in the opposite arrow Z direction.

In this case, the stopper lever 42 is, as shown in FIG. 14, a pair of cylinders 42a, 42a with a predetermined gap between them, and a lever body protruding from these cylinders 42a. 42b and this lever body 42b
A pair of engaging arms 42c protruding from both sides of the claw portion 4 and a claw portion 4 formed on one outer peripheral surface of the pair of cylindrical bodies 42a.
The lever body 4 has a shape integrally formed with 2d.
The tip surface of 2b functions as a stopper surface 42e that comes into contact with the tip portion of the lock plate 11.

The stopper lever 42 thus constructed
Is in a locked position where the stopper surface 42e is opposed to the tip of the lock plate 11 from below in a state where the tubular body 42a is fitted around the support shaft 41 (see FIG. 16A).
And an unlocked position in which the stopper surface 42e is retracted from the movement path of the lock plate 11 (see FIGS. 11 and 16).
(See (b)).

Further, as shown in FIG. 15, the cam lever 43 is a cylindrical body 42 of the stopper lever 42.
a cylindrical body 43a shaped to fit into the space between a and 42a
And a lever main body 43b protruding from the cylindrical body 43,
The lever body 43b is integrally formed with a claw portion 43c that projects from the side surface of the base portion of the lever body 43b and contacts the claw portion 42d of the stopper lever 42 in the arrow Z direction. , Lock plate 11
It is configured to function as a cam surface 43d that comes into contact with the tip of the.

The cam lever 43 thus constructed is
With the cylindrical body 43a fitted around the support shaft 41, the operating position (see FIG. 11) in which the cam surface 43d is opposed to the tip of the lock plate 11 from below and the cam surface 43d is fixed to the lock plate 11 as shown in FIG. It reciprocates between the non-acting position (see FIGS. 16A and 16B) retracted from the movement locus.

The electromagnetic solenoid 44 is fixed on the stay 40 by caulking means or the like, and the flange portion 44b provided on the plunger 44a is engaged with the engaging arm 42c of the stopper lever 42. It is connected to the stopper lever 42.

The first torsion coil spring 45 is provided on one side of the pair of cylindrical bodies 42a of the stopper lever 42.
(Corresponding to the first spring means in the invention of claim 1)
Is wound between the stopper lever 42 and the stay 40 so as to exert a spreading force, and thus the stopper lever 42 is always urged in the unlock position direction (arrow Z direction). There is.

A second torsion coil spring 46 is provided on the other side of the pair of cylindrical bodies 42a of the stopper lever 42.
(Corresponding to the second spring means in the invention of claim 1) is wound. The torsion coil spring 46 has one end connected to the cam lever 43 and the other end connected to the stopper lever 4.
2 so that the lever bodies 43b and 4 of the cam lever 43 and the stopper lever 42 are connected to each other.
2b is configured to exert a force of rotating in the direction of approaching each other. As a result, the cam lever 43 is in a state of being connected to the stopper lever 42 via the second torsion coil spring 46, and the cam surface 43d is normally opposed to the tip portion of the lock plate 11. It is biased and held in the operating position.

In this case, the second torsion coil spring 4
6 has a spring force larger than that of the first torsion coil spring 45. The spring force of the electromagnetic force between the holding force of the plunger 44 a by the electromagnetic solenoid 44 and the spring force of the first torsion coil spring 45. It is set to be smaller than the resultant force. The claws 42d and 43c of the stopper lever 42 and the cam lever 43 have a function of holding a gap between the lever bodies 42b and 43b in accordance with the mutual contact.

According to the present embodiment thus constructed, the stopper lever 42 is normally urged in the unlock position direction by the first torsion coil spring 45, so that the electromagnetic solenoid 44 is switched on and off. It is held in the unlocked position regardless of the above. From this state,
When the lock plate 11 is moved in the direction of the arrow Y in FIG. 11 in response to a pressing operation of a detent knob (not shown), the tip end of the lock plate 11 and the cam lever 43.
By the cam action in accordance with the contact with the cam surface 43d, the moving force in the direction opposite to the arrow Z is applied to the cam lever 43, and the moving force is applied to the stopper lever 42 by the second torsion coil. Applied through spring 46.

When the electromagnetic solenoid 44 is de-energized when the detent knob is pressed, the force for holding the stopper lever 42 at the unlocked position is the spring force of the first torsion coil spring 45. However, since the spring force is set to be smaller than the spring force of the second torsion coil spring 46, the cam lever 43 moves in the opposite arrow Z direction in response to the pressing operation of the detent knob as described above.
16 (a), the stopper lever 42 is also attached to the first torsion coil spring 4 when rotated in the direction.
It is rotated in the opposite arrow Z direction, that is, in the lock position direction, against 5.

When the stopper lever 42 is rotated to the lock position in this manner, the tip of the lock plate 11 comes into contact with the stopper surface 42e of the stopper lever 42, and the movement of the lock plate 11 is prohibited. Therefore, the pressing operation of the detent knob is invalidated.

On the other hand, when the electromagnetic solenoid 44 is energized when the detent knob is pressed, the electromagnetic solenoid 44 attracts and holds the plunger 44a. In this state, the stopper lever 4
The force for holding 2 in the unlocked position is the resultant force of the holding force of the plunger 44a by the electromagnetic solenoid 44 and the spring force of the first torsion coil spring 45. In this case, since the spring force of the second torsion coil spring 46 is set to a value smaller than the above-mentioned resultant force, a moving force in the lock position direction is applied to the stopper lever 42 according to the pressing operation of the detent knob. 16 (b), only the cam lever 43 is moved in the direction opposite to the arrow Z in accordance with the deformation of the second torsion coil spring 46, and the stopper lever 42 remains in the unlocked position. Become. For this reason, the stopper surface 42e of the stopper lever 42 is retracted from the movement trajectory of the lock plate 11,
Since the movement of the lock plate 11 in the direction of the arrow Y is allowed, the pressing operation of the detent knob is validated.

17 and 18 show a seventh embodiment of the present invention which is a modification of the sixth embodiment, and only the portions different from the sixth embodiment will be described below. That is, in the seventh embodiment, in place of the first torsion coil spring 45 and the second torsion coil spring 46 in the sixth embodiment, the first torsion coil spring 47 (in the invention of claim 3). It is characterized in that a so-called driven member spring means) and a second torsion coil spring 48 (corresponding to stopper member spring means in the invention of claim 3) are provided.

In this case, the first torsion coil spring 4
7 is wound around one side of the pair of cylindrical bodies 42a of the stopper lever 42 so as to exert a spreading force between the cam lever 43 and the stay 40, whereby the first torsion coil spring 47 is provided. Cam lever 43 that receives the spring force of
Always presses the stopper lever 42 in the unlock position direction (arrow Z direction) via the claw portions 43c and 42d.

In addition, the second torsion coil spring 48 (see FIG.
8) is a pair of cylindrical bodies 4 included in the stopper lever 42.
On the other side of 2a, the stopper lever 42 and the stay 40 are wound so as to exert an expanding force, so that the stopper lever 42 is always in the lock position direction (counter arrow Z direction). Being energized.

In this case, the spring force of the second torsion coil spring 48 is set to be smaller than the spring force of the first torsion coil spring 47 and the holding force of the plunger 44a by the electromagnetic solenoid 44. Therefore, the stopper lever 42 is always operated as shown in FIG.
The cam lever 43, which receives the spring force of the first torsion coil spring 47, presses the cam lever 43 through the claw portions 43c and 42d and holds the unlocked position.

In the seventh embodiment thus constructed, the lock plate 11 is released from the state where the stopper lever 42 is held at the unlock position (the state shown in FIG. 17) in response to the pressing operation of the detent knob (not shown). When the cam lever 43 is moved in the operation direction (arrow Y direction), the cam lever 43 is moved to the first position by the cam action according to the contact between the tip portion of the lock plate 11 and the cam surface 43d of the cam lever 43.
Is rotated in the direction opposite to the arrow Z direction against the spring force of the torsion coil spring 47, and accordingly, the cam lever 43 is displaced to the position where the pressing of the stopper lever 42 is released to move the stopper lever 42 in the locked position direction ( The movement in the opposite arrow Z direction) is allowed.

When the electromagnetic solenoid 44 is cut off during the pressing operation of the detent knob, the stopper lever 42 moves the second torsion coil spring 48.
It is moved to the locked position by the spring force of. When the stopper lever 42 is moved to the lock position in this manner, the tip of the lock plate 11 comes into contact with the stopper surface 42e of the stopper lever 42, and the movement of the lock plate 11 is prohibited. Therefore, the further pressing operation of the detent knob is invalidated.

On the other hand, when the electromagnetic solenoid 44 is energized when the detent knob is pressed, the electromagnetic solenoid 44 attracts and holds the plunger 44a. At this time, since the spring force of the second torsion coil spring 48 is set to a value smaller than the holding force of the plunger 44a by the electromagnetic solenoid 44, the cam lever 43 is displaced in the same manner as described above according to the operation of the detent knob. Even when the stopper lever 42 is allowed to move in the lock position direction, the stopper lever 42 resists the spring force of the second torsion coil spring 48 by the holding force of the plunger 44a. It remains held in the locked position. Therefore, the movement of the lock plate 11 in the direction of the arrow Y is allowed, and the pressing operation of the detent knob is validated.

FIGS. 19 and 20 show an eighth embodiment of the present invention which has the same effect as that of the first embodiment.
Only the parts different from the first embodiment will be described below.
That is, the stopper lever 49 as a stopper member and the cam lever 50 as a driven member are parallel to the stay 51 with respect to the support shaft 52 erected on the stay 51.
It is rotatably supported in the directions of the arrow W and the opposite arrow W.

Specifically, the stopper lever 49 is
A lock position in which a stopper surface 49a formed at the tip of the lock plate 11 faces the tip of the lock plate 11 from below;
The stopper surface 49a is configured to reciprocally rotate between an unlocked position (state shown in FIGS. 19 and 20) in which the stopper surface 49a is retracted from the movement path of the lock plate 11.

In the cam lever 50, the cam surface 50a formed at the tip end portion of the cam plate 50a and the operating position in which the tip end portion of the lock plate 11 is opposed to the tip end portion of the lock plate 11 from below (the state shown in FIGS. 19 and 20), and the cam surface 50a. Is reciprocally rotated between a non-acting position retracted in the direction opposite to the arrow W from the movement path of the lock plate 11.

The electromagnetic solenoid 53 is fixed on the stay 51 by caulking means, and is erected on the stopper lever 49 between the plunger 53a and the flange portion 53b provided on the plunger 53a. The stopper lever 49 is connected by engaging the pin 49b.

Around the support shaft 52, a first torsion coil spring 54 (corresponding to the first spring means in the invention of claim 1) spreads between the stopper lever 49 and the stay 51. The stopper lever 49 is wound so as to exert a force, so that the stopper lever 49 is normally urged in the unlock position direction (arrow W direction).

Further, a second torsion coil spring 55 (corresponding to the second spring means in the invention of claim 1) provided coaxially with the first torsion coil spring 54 is wound. The torsion coil spring 55 has one end connected to the cam lever 50 and the other end connected to the stopper lever 49. As a result, the cam lever 50 is in a state of being connected to the stopper lever 49 via the second torsion coil spring 55, and the cam surface 50a is normally opposed to the tip portion of the lock plate 11. It is biased and held in the operating position.

In this case, the second torsion coil spring 5
5 has a larger spring force than the first torsion coil spring 54. The spring force of the electromagnetic force between the holding force of the plunger 53 a by the electromagnetic solenoid 53 and the spring force of the first torsion coil spring 54. It is set to be smaller than the resultant force.

According to such a configuration, FIG. 19 and FIG.
When the lock plate 11 is moved in the direction of the arrow Y in FIG. 20 from the state shown in 0 in response to the pressing operation of the detent knob (not shown), the tip portion of the lock plate 11 and the cam surface 50a of the cam lever 50 are brought into contact with each other. By the cam action corresponding to the contact, a moving force in the direction opposite to the arrow W is applied to the cam lever 50, and the moving force is applied to the stopper lever 49 through the second torsion coil spring 55.

When the electromagnetic solenoid 53 is de-energized during such a detent knob pressing operation, the force for holding the stopper lever 49 in the unlocked position is the spring force of the first torsion coil spring 54. However, since the spring force is set to be smaller than the spring force of the second torsion coil spring 55, the cam lever 50 causes the counter-arrow W to move in response to the pressing operation of the detent knob as described above.
When rotated in the direction, the stopper lever 49 also rotates in the direction opposite to the arrow W, that is, in the lock position direction, against the first torsion coil spring 54.

When the stopper lever 49 is thus rotated to the lock position, the tip of the lock plate 11 comes into contact with the stopper surface 49a of the stopper lever 49, and the movement of the lock plate 11 is prohibited. Therefore, the pressing operation of the detent knob is invalidated.

On the other hand, when the electromagnetic solenoid 53 is energized when the detent knob is pressed, the electromagnetic solenoid 53 attracts and holds the plunger 53a. In this state, the stopper lever 4
The force for holding 9 in the unlocked position is the resultant force of the holding force of the plunger 53a by the electromagnetic solenoid 53 and the spring force of the first torsion coil spring 54. In this case, the second
Since the spring force of the torsion coil spring 55 is set to a value smaller than the resultant force, when the moving force in the lock position direction is applied to the stopper lever 49 in response to the pressing operation of the detent knob, According to the deformation of the torsion coil spring 55, only the cam lever 50 is moved in the direction opposite to the arrow W, and the stopper lever 49 remains held at the unlock position. Therefore, the stopper surface 49a of the stopper lever 49 is retracted from the movement path of the lock plate 11, and the movement of the lock plate 11 in the direction of the arrow Y is allowed, so that the pressing operation of the detent knob is validated. Will be.

FIG. 21 shows a ninth embodiment of the present invention in which the above eighth embodiment is modified, and only the portions different from the eighth embodiment will be described below. That is, in the ninth embodiment, the first torsion coil spring 54 and the second torsion coil spring 55 in the eighth embodiment are replaced by the first embodiment.
Compression coil spring 56 (corresponding to the driven member spring means in the invention of claim 3) and the second second compression coil spring 57 (corresponding to the stopper member spring means in the invention of claim 3). It is characterized by the provision of.

In this case, the first compression coil spring 56
Is the projection 5 provided on the cam lever 50 and the stay 51.
The cam lever 50, which is interposed between the first lever 1a and the spring 1a so as to exert an extension force, receives the spring force of the first compression coil spring 56, and the stopper lever 49 is always unlocked in the unlock position direction (arrow W direction). ).

Further, the second compression coil spring 57 is interposed between the stopper lever 49 and the electromagnetic solenoid 53 so as to exert an extension force, whereby the stopper lever 49 is always in the lock position direction. It is urged in the direction (counter arrow W).

In this case, the spring force of the second compression coil spring 57 is set to a value smaller than the spring force of the first compression coil spring 56 and the holding force of the plunger 53a by the electromagnetic solenoid 53. Therefore, the stopper lever 49 is always in the first position as shown in FIG.
Cam lever 50 that receives the spring force of the compression coil spring 56 of
It is pushed by and is held at the unlock position.

In the ninth embodiment thus constructed, the lock plate 11 is released from the state in which the stopper lever 49 is held at the unlock position (the state shown in FIG. 21) in response to the pressing operation of the detent knob (not shown). When moved in the operating direction, the cam lever 50 resists the spring force of the first compression coil spring 56 by the cam action according to the contact between the tip of the lock plate 11 and the cam surface 50a of the cam lever 50. Is rotated in the direction opposite to the arrow W, and accordingly, the cam lever 50 is displaced to the position where the pressing of the stopper lever 49 is released to allow the stopper lever 49 to move in the lock position direction (direction opposite the arrow W). Like

When the electromagnetic solenoid 53 is cut off during the pressing operation of the detent knob, the stopper lever 49 is moved to the lock position by the spring force of the second compression coil spring 57. Become. When the stopper lever 49 is moved to the lock position in this way, the tip end portion of the lock plate 11 moves to the stopper lever 4
Since it comes into contact with the stopper surface 49a of 9 and the movement of the lock plate 11 is prohibited,
Further pressing of the detent knob is disabled.

On the other hand, when the electromagnetic solenoid 53 is energized when the detent knob is pressed, the electromagnetic solenoid 53 attracts and holds the plunger 53a. At this time, the spring force of the second compression coil spring 57 causes the plunger 5 to move by the electromagnetic solenoid 53.
Since it is set to a value smaller than the holding force of 3a, the cam lever 50 is displaced in the same manner as described above in response to the operation of the detent knob, and the stopper lever 49 is allowed to move in the lock position direction. Even at this time, the stopper lever 49 remains held in the unlocked position against the spring force of the second compression coil spring 57 due to the holding force of the plunger 53a. Therefore, the movement of the lock plate 11 is permitted, and the detent knob pressing operation is validated.

In this embodiment, the functions of the first compression coil spring 56 and the second compression coil spring 57 may be obtained by a torsion coil spring wound around the support shaft 52. .

22 to 26 show a tenth embodiment of the present invention having the same effect as that of the first embodiment,
Only parts of the tenth embodiment different from the first embodiment will be described below. That is, the stopper block 58 as a stopper member and the cam member 59 as a driven member are arranged on the stay 60 so as to be linearly movable in the arrow V and counter arrow V directions in FIG.

In this case, the stopper block 58 is
As shown in FIG. 25, a groove portion 58a for guiding the movement of the cam member 59 is formed on the lower surface thereof, and a notch portion 58 oriented in the direction orthogonal to the moving direction is formed on the upper surface.
b is formed, and one of the upper surface portions defined by the cutout portion 58b functions as a stopper surface 58c that comes into contact with the tip end portion of the lock plate 11. Specifically, the stopper block 58 has a lock position where the stopper surface 58c faces the tip of the lock plate 11 from below, and an unlock position where the stopper surface 58c is retracted from the movement path of the lock plate 11. (The state shown in FIGS. 22 and 23). A recess 58d for receiving a spring is formed on the end surface of the stopper block 58, particularly on the end surface opposite to the stopper surface 58c. The stopper block 58 is configured to move linearly by being guided by guide means (not shown).

As shown in FIG. 26, the cam member 59 includes a guide bar 59a which is inserted into the groove 58a of the stopper block 58, a cam projection 59b which is integrally formed on one end of the guide bar 59a, and a guide bar 59a. 59a has a retaining projection 59c integrally formed on the other end side of 59a, and the cam surface 59d formed on the cam projection 59b is opposed to the tip of the lock plate 11 from below. It is configured to reciprocally rotate between an acting position (states of FIGS. 22 and 23) and a non-acting position in which the cam surface 59d is retracted from the movement locus of the lock plate 11 in the direction of the arrow V. The cam member 59 has a retaining projection 5
A recess 59e for receiving a spring is formed in 9c so as to face the recess 58d of the stopper block 58.

On the other hand, an arm 61 is provided on the stay 60 so as to be rotatable in the directions of arrow U and counter arrow U in FIG. The tip of the arm 61 is slidably engaged with the notch portion 58b of the stopper block 58, and the stopper block 58 reciprocates in the directions of arrow V and the opposite arrow V in accordance with the reciprocal rotation thereof. It is configured.

The electromagnetic solenoid 53 is fixed on the stay 60 by caulking means or the like, and the plunger 5 thereof is fixed.
The arm 61 is connected to the arm 61 by engaging a pin 61a provided upright on the arm 61 between the 3a and the flange portion 53b.

A torsion coil spring 63 (corresponding to the first spring means in the invention of claim 1) is wound around the support shaft 62 so as to bias the arm 61 in the direction of arrow U. ing. In addition, the recess 58 on the stopper block 58 side
A compression coil spring 64 (corresponding to the second spring means in the invention of claim 1) is provided between d and the recess 59e on the side of the cam member 59 so as to exert an extension force therebetween. ing. As a result, the cam member 59 is in a state of being connected to the stopper block 58 via the compression coil spring 64, and the cam surface 5 is always in the normal state.
9d is urged and held in an operating position where the tip of the lock plate 11 is opposed.

In this case, the compression coil spring 64 has a larger spring force than the torsion coil spring 63. The spring force is the holding force of the electromagnetic solenoid 53 for the plunger 53a and the torsion coil spring 63. It is set to be smaller than the resultant force with the spring force.

According to such a configuration, FIG. 22 and FIG.
When the lock plate 11 is moved from the state shown in FIG. 3 in the direction of the arrow Y in FIG. 22 in response to the pressing operation of the detent knob (not shown), the tip of the lock plate 11 and the cam surface 59d of the cam member 59 are separated from each other. By the cam action corresponding to the contact, a moving force in the direction opposite to the arrow V is applied to the cam member 59, and the moving force is applied to the stopper block 58 through the compression coil spring 64.

When the electromagnetic solenoid 53 is de-energized during such a detent knob pressing operation, the force that holds the stopper block 58 in the unlocked position is only the spring force of the torsion coil spring 63. However, since the spring force is set to be smaller than the spring force of the compression coil spring 64, when the cam member 59 is rotated in the direction opposite to the arrow V in response to the pressing operation of the detent knob as described above, the stopper block is rotated. 58 also rotates in the direction opposite to the arrow V, that is, in the lock position direction, against the torsion coil spring 63.

When the stopper block 58 is thus rotated to the lock position, the tip of the lock plate 11 comes into contact with the stopper surface 58c of the stopper block 58, and the movement of the lock plate 11 is prohibited. Therefore, the pressing operation of the detent knob is invalidated.

On the other hand, when the electromagnetic solenoid 53 is energized when the detent knob is pressed, the electromagnetic solenoid 53 attracts and holds the plunger 53a. In this state, the force that holds the stopper block 58 in the unlocked position is the resultant force of the holding force of the plunger 53a by the electromagnetic solenoid 53 and the spring force of the torsion coil spring 63. In this case, since the spring force of the compression coil spring 64 is set to a value smaller than the resultant force, when the moving force in the lock position direction is applied to the stopper block 58 in response to the pressing operation of the detent knob, Only the cam member 59 is moved in the direction opposite to the arrow V according to the deformation of the torsion coil spring 64, and the stopper block 58 remains held in the unlock position. Therefore, the stopper surface 58 of the stopper block 58 is
Since c is retracted from the movement path of the lock plate 11 and the movement of the lock plate 11 in the arrow Y direction is allowed, the pressing operation of the detent knob is validated.

As shown in FIG. 27 showing the eleventh embodiment of the present invention, instead of the stay 60 in the tenth embodiment, the stopper block 58 and the cam member arrangement portion are bent to the arm 61 side. It is also possible to provide the stay 60 ′. In such a configuration, the electromagnetic solenoid 53, which is a large-sized component, is arranged in a state of being inclined with respect to the moving direction of the lock plate 11. As a result, the space efficiency can be improved, and the device can be stored easily.

The present invention is not limited to the above-described embodiments, but is not limited to the shift lock device for automobiles, but can be widely applied to vehicle lock devices using electromagnetic solenoids in general. It can be implemented by appropriately modifying within the range.

By adopting a configuration in which the spring force of the spring means is set to a value smaller than each of the spring force of the first spring means and the plunger holding force of the electromagnetic solenoid, a relatively small force is applied to the electromagnetic solenoid. Since it suffices to use what is generated, the electromagnetic solenoid can be downsized, and when mounting the electromagnetic solenoid, it is possible to achieve a beneficial effect for a vehicle that is less likely to be restricted in space, and to have an electromagnetic effect. This has an excellent effect that noise due to the operation of the solenoid can be suppressed at the same time.
