Description

  The present invention relates to an engine starter, and more particularly, to an engine starter that can be suitably used for an apparatus including a knock block mechanism and a key interlock mechanism.

  A conventional engine starter includes, as an example, a knock block mechanism and an interlock mechanism.

  The no-block mechanism is a mechanism for preventing an unauthorized rotation operation of the electronic key or the rotary knob in a state where electronic verification using the ID code is not properly performed. As an example of this no-block mechanism, as shown in FIG. 13A, a rotor 103 into which an electronic key is inserted, a rotor housing 106 having a no-block groove 106a, and a no-block pin engaged with the no-block groove 106a. 107, a first coil spring 105 for engaging the no-block pin 107 with the no-block groove 106a, and a first suction solenoid 112 for engaging the no-block pin 107 with the no-block groove 106a when energized based on the result of electronic verification. , And a second coil spring 111 for bringing the first plunger 112 a into contact with the no-block pin 107.

  When electronic verification is not properly performed in the no-block mechanism, the first suction solenoid 112 is not energized to drive the first plunger 112a as shown in FIG. Since the pin 107 is engaged with the no-block groove 106a by using the elastic force of the first coil spring 105 and the second coil spring 111, the electronic key or the rotary knob cannot rotate the rotor 103. On the other hand, when the electronic verification is properly performed, as shown in FIG. 13B, the first suction solenoid 112 is energized to drive the first plunger 112a, and the first plunger 112a is Since the no-block pin 107 is driven against the elastic force of the first coil spring 105 and the second coil spring 111, the engagement between the no-block pin 107 and the no-block groove 106a is released. Thereby, the electronic key or the rotary knob can rotate the rotor 103.

  In addition, the interlock mechanism allows the electronic key or rotary knob to rotate backward (rotation from the accessory position to the off position by the electronic key or rotary knob) when the shift lever has not selected the parking range (the parking position selection position). This is a mechanism for preventing erroneous operation. As an example of this interlock mechanism, as shown in FIG. 14A, the anti-rotation disc 110 interlocked with the rotation operation of the rotor 103, and the anti-rotation disc by energization when the shift lever selects the parking range. The second suction solenoid 113 for engaging the second plunger 113a with the engagement step portion 110c of 110, and the third coil spring for separating the second plunger 113a from the engagement step portion 110c of the rotation prevention disk 110 114.

  In the interlock mechanism, when the shift lever selects a range other than the parking range, as shown in FIG. 14 (a), the second suction solenoid 113 is turned on by the third coil spring by energizing the second suction solenoid 113. In order to drive the second plunger 113 a against the elastic force of 114, the second plunger 113 a is engaged with the engagement step portion 110 c of the rotation prevention disk 110. As a result, the electronic key or the rotary knob cannot rotate the rotor 103 in the reverse direction. On the other hand, when the shift lever selects the parking range, the second suction solenoid 113 is not energized to drive the second plunger 113a, as shown in FIG. The engagement between the second plunger 113a and the engagement step portion 110c of the rotation prevention disk 110 is released by the elastic force. Thus, the electronic key 2A or the rotary knob 2B can rotate the rotor 103 in the reverse direction.

  Note that, in both the no-block mechanism and the interlock mechanism, it is possible to ensure the stop state of the automobile engine when the electric system fails. That is, when the first suction solenoid 112 is not energized due to a failure in the electrical system, the no-block mechanism works so that the key cannot rotate and the engine cannot be started. The second suction due to the failure in the electrical system. When the solenoid 113 is not energized, the interlock mechanism does not work and the key can be removed.

  However, since the conventional engine starter requires two suction solenoids, it is difficult to save the space of the solenoids 112 and 113. Further, since the plunger must be driven against the elastic force of the second coil spring 111 or the third coil spring 114 in any of the suction solenoids, the power consumption of the suction solenoids 112 and 113 increases, and the solenoids It was difficult to save energy of 112 and 113.

  Accordingly, an object of the present invention is to provide an engine starter capable of realizing space saving and energy saving of a solenoid used for a knock block mechanism and an interlock mechanism.

  [1] In order to achieve the above object, the present invention is arranged such that a push-in operation and a rotation operation are performed using an electronic key or a rotary knob, and a push-in operation of the rotor is performed in the push-in direction of the rotor. The shaft engages with the rotor and rotates in conjunction with the engaged rotor, and biases the rotor in a direction to separate the rotor from the shaft. A first elastic member that is arranged in a component arrangement hole that extends in a direction orthogonal to the pushing direction of the rotor in the rotor, and at least one of both ends thereof protrudes from the component arrangement hole. A lock pin that is formed, a second elastic member that biases the lock pin in a direction in which one end of the lock pin protrudes from the component placement hole, A no-block protrusion that prevents engagement of the rotor and the shaft by abutting against one end of the lock pin during the push-in operation of the rotor, and reverse rotation of the rotor from the predetermined rotational position toward the initial position An interlock protrusion that prevents reverse rotation of the rotor by contacting the other end of the lock pin protruding from the component placement hole only in the case of operation and preventing passage of the other end of the lock pin; The first is formed so as to be movable inward and outward in the direction orthogonal to the pushing direction of the rotor, and prevents one end of the lock pin from coming into contact with the no-block protrusion during the pushing operation of the rotor. A lock pin pushing portion having an inclined portion, and a second inclined portion that pushes one end of the lock pin into the component placement hole when the rotor rotates in the reverse direction; and the second elastic member A third elastic member that urges the lock pin pushing portion with an elastic force weaker than an elastic force to the inside in a direction perpendicular to the pushing direction of the rotor and a plunger linked to the lock pin pushing portion when energized are held. In addition, when a desired electronic collation is performed during the pushing operation of the rotor, or when the operation lever of the transmission is in a position other than the parking selection position during the reverse rotation operation of the rotor, the plunger is energized. And a holding solenoid for holding the engine.

  According to this engine starting device, the single block solenoid and the key interlock can be performed using one holding solenoid.

  [2] The lock pin pushing portion is a slide plate formed in an L-shape in plan view that overlaps an L-shaped section on the locus of the lock pin that moves in an L-shape in plan view, and push-in operation of the rotor The first inclined portion on the side facing the lock pin at the time of the rotation, and the second inclined portion on the side opposite to the lock pin at the time of the reverse rotation operation of the rotor, The engine starting device according to [1] may be used.

  According to this engine starting device, since the lock pin pushing portion is arranged on the locus of the lock pin, the lock and the key interlock can be smoothly performed.

  [3] The no-block protrusion has an L-shape in a plan view surrounding the outside of the lock pin pressing portion when viewed from the traveling direction of the lock pin, and each side thereof is more than each side of the lock pin pressing portion. Each of the lock pins is formed in a shortened shape, and one end of the lock pin is pushed in after the other end of the lock pin passes through the interlock protrusion on the opposite side of the lock pin during the reverse rotation operation of the rotor. The lock pin has a third inclined portion, and one end of the lock pin is on a boundary line between the lock pin push-in portion and the no-block projection and both the lock pin push-in portion and the no-block projection The engine starter according to [2] above, which is disposed at a position passing through a straight line that abuts.

  According to this engine starting device, the no-block projection does not obstruct the key interlock mechanism during reverse rotation of the rotor, and the no-block projection temporarily bears the pushing of the lock pin during the pushing operation of the rotor. The power consumption of the holding solenoid that holds the lock pin pushing portion can be suppressed.

  [4] The interlock protrusion is opposed to the other end of the lock pin in the forward rotation direction of the rotor from the initial position toward the predetermined rotation position, with a fourth elastic member biased in the protrusion direction. A pin shape having a fourth inclined surface and a vertical surface facing the other end of the lock pin in the reverse rotation direction of the rotor from the predetermined rotation position toward the initial position, When the other end abuts against the fourth inclined surface, the lock pin is pressed against the elastic force of the fourth elastic member in the direction opposite to the protruding direction by the other end of the lock pin. The engine starter according to any one of [1] to [3] above, wherein the engine starter is configured to allow passage of the other end of the engine.

  According to this engine starting device, the shape and structure of the interlock protrusion can be simplified.

  Hereinafter, an engine starting device of the present invention will be described with reference to an embodiment thereof.

  As shown in FIGS. 1 and 2, the engine starter 1 of the present embodiment mainly includes a rotor 3, a shaft 4, a first elastic member 5, a lock pin 7, a second elastic member 8, and a no-block protrusion. A portion 9, an interlock projection 10, a lock pin pushing portion 11, a third elastic member 12, and a holding solenoid 13.

  As shown in FIGS. 1 and 2, the rotor 3 is formed in a columnar shape having a component arrangement hole 3b, an engaging convex portion 3c, and a key cylinder 3a. The rotor 3 is rotated along the cylindrical inner surface 6c of the rotor cylinder 6 about the key insertion direction (right direction in FIG. 2; this direction is also the pushing direction of the rotor 3). It has a cylindrical side surface 3d.

  As shown in FIG. 3, the component arrangement hole 3b of the rotor 3 is located in front of the key cylinder 3a in the key insertion direction. As shown in FIG. 3, the component arrangement hole 3 b is formed in the rotor 3 so as to extend in a direction orthogonal to the pushing direction of the rotor 3.

  The engaging projection 3c of the rotor 3 protrudes in the pushing direction from the front end surface in the pushing direction of the rotor 3 (key insertion direction of the rotor 3). The engaging projection 3c of the rotor 3 is engaged with the engaging recess 4a of the shaft 4 when the rotor 3 is pushed using the electronic key 2A shown in FIG. 1 or the rotary knob 2B shown in FIG. It has become.

  As shown in FIGS. 1 and 2, the key cylinder 3 a of the rotor 3 is formed so that the electronic key 2 </ b> A is partially inserted into the rotor 3. If the electronic key 2A is a rectangular parallelepiped shape, the key cylinder 3a is a square hole.

  The electronic key 2A is a fob type electronic key corresponding to, for example, a keyless entry system (so-called smart entry system), a wireless key system, and the like, and includes an ID code for electronic verification. In addition, as shown in FIG. 1, the electronic key 2 </ b> A of the present embodiment is preferably formed in a rectangular parallelepiped shape from the viewpoint of increasing the number of remote buttons such as door locks associated with convenience.

  The name of the key cylinder 3a is a name when the electronic key 2A shown in FIG. 1 is used, and the name when the rotary knob 2B is used is a knob engaging portion to be precise. However, even though their names and detailed shapes are different, the electronic key 2A or the rotary knob 2B is inserted in order to rotate the rotor 3, and their main actions at the time of rotating the rotor 3 are as follows. It is the same. Therefore, in the present embodiment, the name of the key cylinder 3a is unified even when either the electronic key 2A or the rotary knob 2B is employed.

  The shaft 4 is arranged in the pushing direction of the rotor 3 (key insertion direction). The shaft 4 has an engaging recess 4a on the rear side of the rotor 3 in the pushing direction (the rotor 3 side). The engaging recess 4a engages with the engaging protrusion 3c of the rotor 3 when the rotor 3 is pushed. Thereby, since the rotor 3 and the shaft 4 are interlocked in the rotation operation of the rotor 3, the ignition switch is turned on or off by the rotation operation.

  As shown in FIG. 2, the first elastic member 5 is disposed between the rotor 3 and the shaft 4 in the pushing direction of the rotor 3, and urges the rotor 3 in a direction in which the rotor 3 is pulled away from the shaft 4. . The first elastic member 5 is preferably a coil spring from the relationship between economy and elastic force.

  The lock pin 7 is arranged in the component arrangement hole 3 b of the rotor 3 extending in a direction orthogonal to the pushing direction of the rotor 3. The lock pin 7 is preferably formed in a shape in which two rods are combined such that one end 7a is thick and chamfered and the other end 7b is thin.

  Further, the lock pin 7 is formed in such a length that at least one of its both ends protrudes from the component arrangement hole 3b. In the present embodiment, one end 7a of the lock pin 7 protrudes from the component placement hole 3b at the initial position of the rotor 3, and the other end 7b of the lock pin 7 is pushed by pushing the one end 7a of the lock pin 7 into the component placement hole 3b. Is set so as to protrude from the component placement hole 3b.

  Further, as shown in FIGS. 2 to 4, the lock pin 7 has one end 7a on the boundary line between the lock pin pushing portion 11 and the no-block projection 9, and the lock pin pushing portion 11 and the no-block projection. 9 is preferably disposed at a position that passes through a straight line that abuts any one of 9. Thereby, the locus | trajectory L of the one end 7a of the lock pin 7 becomes L shape in planar view as shown in FIG.

  As shown in FIG. 2, the second elastic member 8 is provided in the component arrangement hole 3b, and biases the lock pin 7 in a direction in which one end 7a of the lock pin 7 protrudes from the component arrangement hole 3b. . The second elastic member 8 is preferably a coil spring from the relationship between economy and space constraints.

  As shown in FIGS. 2 to 4, the no-block protrusion 9 is disposed in the rotor cylinder 6 in front of the rotor 3 in the pushing direction as viewed from one end 7 a of the lock pin 7. The no-block protrusion 9 is a member that prevents engagement between the rotor 3 and the shaft 4 by abutting against one end 7 a of the lock pin 7 when the rotor 3 is pushed.

  Here, when the lock pin pushing portion 11 is formed in an L shape in a plan view, the no-block protrusion 9 has a direction of travel of the lock pin 7 (one end 7a of the lock pin 7 as shown in FIGS. 3 and 4). Preferably, it is formed in an L shape in a plan view surrounding the outside of the lock pin pushing portion 11 as viewed from the direction of pushing the rotor 3 (the lock pin pushing portion 11 is disposed on the cylindrical inner surface 6 c of the rotor cylinder 6. Therefore, in actuality, it becomes a curved L-shape as shown in FIG.

  In this case, it is preferable that the no-block protrusion 9 is formed in a shape in which each side is shorter than each side of the lock pin pushing portion 11. Further, the no-block projection 9 has a third inclined portion 9a on the side opposite to the lock pin 7 (the left end of the no-block projection 9 in FIG. 4) when the rotor 3 is reversely rotated. Is preferred. The third inclined portion 9a has such a shape that after the other end 7b of the lock pin 7 passes through the interlock protrusion 10, the one end 7a of the lock pin 7 is pushed into the component placement hole 3b.

  The interlock protrusion 10 is provided in the rotor cylinder 6 so that the rotor 3 is rotated in the reverse direction as viewed from the other end 7b of the lock pin 7 (the rotor 3 can be rotated at a predetermined rotational position (usually an accessory position, an on position, or a start position). From the position) to the initial position (usually the off position) in FIG. 5, FIG. 7, FIG. 9, and FIG. As shown in FIG. 9, the interlock protrusion 10 abuts against the other end 7 b of the lock pin 7 protruding from the component placement hole 3 b only in the case of the reverse rotation operation of the rotor 3, and the other end of the lock pin 7. It is a member that prevents reverse rotation of the rotor 3 by blocking the passage of 7b.

  Here, the interlock protrusion 10 is preferably a lock pin 7 having a fourth elastic member 10a, a fourth inclined surface 10b, and a vertical surface 10c, as shown in FIG. In this case, the fourth elastic member 10a resides in a hole 6b provided in the radial direction on the cylindrical inner surface 6c of the rotor cylinder 6, and biases the interlock protrusion 10 in the protruding direction.

  As shown in FIG. 5, the fourth inclined surface 10 b is formed in the forward rotation direction of the rotor 3 (the direction in which the rotor 3 is directed from the initial position toward the predetermined rotation position. In FIGS. 5, 7, 9, and 11, the rotor 3 In the clockwise direction) of the lock pin 7 and the other end 7b. When the other end 7b of the lock pin 7 comes into contact with the fourth inclined surface 10b, the interlock protrusion 10 is pushed down in the direction opposite to the protruding direction against the elastic force of the fourth elastic member 10a. As a result, the other end 7 b of the lock pin 7 can pass through the interlock protrusion 10. As long as this action occurs, the fourth inclined surface 10b may be a flat surface or a curved surface.

  As shown in FIG. 9, the vertical surface 10 c is a surface facing the other end 7 b of the lock pin 7 in the reverse rotation direction of the rotor 3. The vertical surface 10 c is in contact with the side surface of the other end 7 b of the lock pin 7, thereby preventing reverse rotation operation of the rotor 3. As long as this action occurs, strict verticality is not required in the vertical surface 10c.

  The lock pin pushing portion 11 is disposed inside the rotor cylinder 6 as shown in FIG. As shown in FIGS. 2 to 4, the lock pin pushing portion 11 is formed to be movable inward (upward in FIG. 2) and outward (downward in FIG. 2) in the direction perpendicular to the pushing direction of the rotor 3. ing. Moreover, this lock pin pushing part 11 has the 1st inclination part 11a and the 2nd inclination part 11b.

  As shown in FIGS. 2 to 4, the first inclined portion 11 a of the lock pin pushing portion 11 is formed on the side facing the one end 7 a of the lock pin 7 when pushing the rotor 3 (lower end in FIG. 4). Element. When the rotor 3 is pushed in, the first inclined portion 11a pushes one end 7a of the lock pin 7 into the component arrangement hole 3b to be higher than the height of the no-block projection 9 so that one end of the lock pin 7 is pushed. The effect | action which prevents that 7a contact | abuts to the no-block protrusion 9 is produced. However, in order to produce this action, it is a condition that the lock pin pushing portion 11 is located inside (in the upward direction in FIG. 2) in the direction orthogonal to the pushing direction of the rotor 3. In other words, when the lock pin pushing portion 11 is located outside the direction orthogonal to the pushing direction of the rotor 3 (downward in FIG. 2), the action does not occur, and the one end 7 a of the lock pin 7 contacts the knock block protrusion 9. Will be in touch.

  On the other hand, as shown in FIG. 4, the second inclined portion 11 b of the lock pin pushing portion 11 is formed on the side opposite to the one end 7 a of the lock pin 7 during the reverse rotation operation of the rotor 3 (the left end in FIG. 4). Element. The second inclined portion 11b acts to push the one end 7a of the lock pin 7 into the component arrangement hole 3b to the extent that the other end 7b of the lock pin 7 protrudes from the component arrangement hole 3b during the reverse rotation operation of the rotor 3. Cause it to occur. However, in order to produce this action, it is a condition that the lock pin pushing portion 11 is located inside (in the upward direction in FIG. 2) in the direction orthogonal to the pushing direction of the rotor 3. Further, when this action occurs, the other end 7b of the lock pin 7 comes into contact with the vertical surface 10c of the interlock protrusion 10, and the reverse rotation operation of the rotor 3 is prevented. In the case where it is not desired to prevent the above-described action, that is, the reverse rotation operation of the rotor 3, it is a condition that the lock pin pushing portion 11 is located outside (in the downward direction in FIG. 2) in the direction orthogonal to the pushing direction of the rotor 3. .

  Here, as shown in FIGS. 3 and 4, the lock pin pressing portion 11 is preferably a slide plate formed in an L shape in plan view. In this case, as shown in FIG. 4, the lock pin pushing portion 11 is integrally formed with a first inclined portion 11 a and a second inclined portion 11 b, and is L-shaped on the locus L of the lock pin 7. It is preferable that they are arranged so as to overlap the section.

  As shown in FIG. 2, the third elastic member 12 is a member that urges the lock pin pressing portion 11 inward of the direction orthogonal to the pressing direction of the rotor 3 (upward in FIG. 2). The elastic force of the third elastic member 12 is set to be weaker than the elastic force of the second elastic member 8. Therefore, when the lock pin pressing portion 11 is positioned inside the direction orthogonal to the pressing direction of the rotor 3 (upward in FIG. 2) only by the elastic force of the third elastic member 12, the one end 7a of the lock pin 7 is When the lock pin pushing portion 11 comes into contact with the first inclined portion 11a or the second inclined portion 11b of the lock pin pushing portion 11, the lock pin pushing portion 11 is outside the direction perpendicular to the pushing direction of the rotor 3 (downward direction in FIG. 2, FIG. 5). 7, 9, and 11, and downward, and FIGS. 6, 8, 10, and 12 move in the direction toward the back of the drawing. As a result, the one end 7 a of the lock pin 7 is not affected at all by the lock pin pushing portion 11.

  As shown in FIG. 2, the holding solenoid 13 has a plunger 13a. The holding solenoid 13 is formed so as to fix the plunger 13a when energized and to freely move the plunger 13a when deenergized. The holding force of the plunger 13 a is set so that the total holding force obtained by adding the holding force of the plunger 13 a and the elastic force of the third elastic member 12 is stronger than the elastic force of the second elastic member 8. Has been. The total holding force is a force for holding the lock pin pressing portion 11 inside (in the upward direction in FIG. 2) in the direction orthogonal to the pressing direction of the rotor 3, and the elastic force of the second elastic member 8 holds the lock pin 7 on the rotor 3. This is a driving force to the outside of the direction perpendicular to the pushing direction (downward in FIG. 2).

  The plunger 13a is controlled to be energized when one of the following two conditions is satisfied. The first of the two conditions is when a desired electronic verification is performed during the pushing operation of the rotor 3. That is, the electronic collation using the ID code has a desired result. The second condition of the above two conditions is when the operation lever of the transmission is at a position other than the parking selection position during the reverse rotation operation of the rotor 3.

  The parking selection position is the P (parking) range for AT (automatic transmission) vehicles, while the positions other than the parking selection position are, for example, the D (drive) range.

  Next, the no block and the key interlock in this embodiment will be described with reference to FIGS.

  First, the no-block mode will be described.

  The no-block non-operation mode occurs when electronic verification is properly performed. In the no-block non-operation mode, as shown in FIGS. 5 and 6, when the holding solenoid 13 is energized, the holding solenoid 13 causes the lock pin pushing portion 11 to move inwardly in the direction perpendicular to the pushing direction of the rotor 3 (the upper side of FIG. Direction, front side of FIG. 6). As shown in FIG. 6, the lock pin pushing portion 11 indicated by a thick line is higher than the no-block protrusion 9 indicated by a thin line. When the push operation of the rotor 3 is performed by the electronic key 2A or the rotary grip, the one end 7a of the lock pin 7 climbs the first inclined portion 11a of the lock pin push portion 11, and the lock pin push portion 11 or the no-block protrusion 9 Move along the top surface. As a result, the engaging convex portion 3 c of the rotor 3 is pushed to the engaging concave portion 4 a of the shaft 4. When the engaging convex portion 3 c of the rotor 3 engages with the engaging concave portion 4 a of the shaft 4, the rotor 3 and the shaft 4 are connected to each other, and a rotation operation can be given to the shaft 4 via the rotor 3.

  Since the interlock protrusion 10 has the fourth inclined surface 10b, the other end 7b of the lock pin 7 is not caught by the interlock protrusion 10 when the rotor 3 is rotated forward. Yes.

  On the other hand, the no-block operation mode occurs when electronic verification is not properly performed. In the no-block operation mode, as shown in FIGS. 7 and 8, the holding solenoid 13 is not energized, so that the lock pin pushing portion 11 is not fixed, and the outer side of the rotor 3 in the direction perpendicular to the pushing direction (the lower side in FIG. 7). Direction, the back direction in FIG. 8). As shown in FIG. 8, the no-block protrusion 9 indicated by a thick line is higher than the lock pin pressing part 11 indicated by a thin line. Even if the pushing operation of the rotor 3 is performed by the electronic key 2A or the rotating grip, the one end 7a of the lock pin 7 moves the lock pin pushing portion 11 outside the direction orthogonal to the pushing direction of the rotor 3 (downward direction in FIG. 5, FIG. 6). The lock pin 7 collides with the no-block protrusion 9 and the pushing operation of the rotor 3 is prevented. As a result, the engaging projection 3c of the rotor 3 cannot engage with the engaging recess 4a of the shaft 4 and the shaft 4 cannot be rotated, so that the ignition switch is turned on via the shaft 4. It becomes impossible to do.

  Next, the key interlock mode will be described.

  The key interlock operation mode occurs in a range other than the P range for an AT vehicle. In the key interlock operation mode, as shown in FIGS. 9 and 10, the holding solenoid 13 is energized, and the lock pin pushing portion 11 is moved inward of the direction perpendicular to the pushing direction of the rotor 3 (upward direction in FIG. 9, It fixes to the near side of FIG. As shown in FIG. 10, the lock pin pushing portion 11 indicated by a thick line is higher than the no-block protrusion 9 indicated by a thin line. In this case, when the rotor 3 is operated in reverse, the one end 7a of the lock pin 7 is pushed up while climbing the second inclined portion 11b of the lock pin pushing portion 11, so that the other end 7b of the lock pin 7 is interlocked. It catches on the vertical surface 10 c of the part 10. As a result, the reverse rotation operation of the rotor 3 is prevented.

  On the other hand, the key interlock non-operation mode occurs in the P range for an AT vehicle. In the key interlock non-operation mode, as shown in FIG. 11 and FIG. 12, the holding solenoid 13 is in a non-energized state, and the lock pin pushing portion 11 is outside the direction perpendicular to the pushing direction of the rotor 3 (the bottom of FIG. 11). Direction, the back direction in FIG. 12). As shown in FIG. 12, the no-block protrusion 9 indicated by a thick line is higher than the lock pin push-in part 11 indicated by a thin line. In this case, when the rotor 3 is rotated in the reverse direction, the one end 7a of the lock pin 7 cannot climb the second inclined surface of the lock pin pushing portion 11, and the lock pin pushing portion 11 is pushed in the pushing direction of the rotor 3. The other end 7b of the lock pin 7 moves to the inside of the component arrangement hole 3b of the rotor 3 and is pulled by the interlock protrusion 10 because Pass without. As a result, the rotor 3 is normally operated, and the electronic key 2A or the rotary knob 2B can be reversely rotated to the off position.

  Next, the operation of the engine starter 1 according to this embodiment will be described.

  In the engine starting device 1 of this embodiment, as shown in FIGS. 2 and 5 to 12, the lock pin pushing portion 11 linked to the plunger 13 a of one holding solenoid 13 links the one end 7 a of the lock pin 7. A push-in operation is performed, and in accordance therewith, it is controlled whether or not one end 7a or the other end 7b of the lock pin 7 is brought into contact with the no-block projection 9 or the interlock projection 10. When they come into contact, no block or key interlock is executed. That is, in the engine starting device 1 of the present embodiment, the single block solenoid and the key interlock can be performed using one holding solenoid 13.

  Further, in the engine starting device 1 of the present embodiment, as shown in FIG. 4, the lock pin pushing portion 11 is a predetermined slide plate having an L shape in plan view described above. Therefore, since the lock pin pushing portion 11 is disposed on the locus L of the lock pin 7, the lock and the key interlock can be smoothly performed.

  Further, in the engine starting device 1 of the present embodiment, as shown in FIG. 4, the no-block protrusion 9 is L-shaped in plan view surrounding the outside of the L-shaped lock pin pushing portion 11 in plan view. And has a predetermined third inclined portion 9a. Further, the one end 7a of the lock pin 7 passes on a boundary line between the lock pin pushing portion 11 and the no-block projection 9 and on a straight line that contacts both the lock pin pushing portion 11 and the no-block projection 9. ing.

  Further, in the engine starting device 1 of the present embodiment, the interlock protrusion 10 is pushed in the opposite direction of the protrusion direction by the fourth inclined surface 10b of the interlock protrusion 10, and the other end 7b of the lock pin 7 is The interlock projection 10 is passed. Thereby, the key interlock can be performed only during the reverse rotation operation of the rotor 3 while simplifying the shape and structure of the interlock protrusion 10.

  That is, according to the engine starting device 1 of the present embodiment, various actions such as a reduction in the number of solenoids and a reduction in power consumption can be obtained, so that space saving and energy saving of solenoids used in the no-block mechanism and the interlock mechanism can be achieved. There is an effect that can be realized.

  In addition, this invention is not limited to embodiment mentioned above etc., A various change is possible as needed.
