Further, the regulation wall 19, the one side wall 21 and the other side wall 23 are each formed on a flat surface.

Further, the pole contact portion 29 of the pole lock 9 that comes into contact with the sleeve 15 is shaped so as to be parallel to the regulation wall 19.

As shown in FIGS. 1 to 7, the casing 3 is configured by combining a plurality of divided cases 31.

A drive shaft 5, a gear member 7, a pole lock 9, an operation mechanism 11, and the like are housed inside the casing 3.

The drive shaft 5 is an intermediate shaft of a transmission mechanism 33 provided on a power transmission path from an engine (not shown) or an electric motor (not shown) as a drive source to wheels.

At this time, if the lock portion 45 is located on the tooth surface of the gear member 7 and does not mesh with the gear member 7, the lock portion 45 is urged toward the tooth bottom of the gear member 7 by the spring 47 as a waiting mechanism. When the lock portion 45 is positioned at the meshing position with the gear member 7, it meshes with the gear member 7.

In such a pole lock 9, a release spring 49 that urges the pole lock 9 to swing in the meshing release direction between the lock portion 45 and the gear member 7 is arranged.

The urging force of the release spring 49 is set to be weaker than that of the spring 47 as a waiting mechanism.

Such a release spring 49 swings the pole lock 9 in the disengagement release direction between the lock portion 45 and the gear member 7 when the contact between the pole contact portion 29 of the pole lock 9 and the sleeve 15 is released.

The swing of the pole lock 9 disengages the lock portion 45 from the gear member 7, and releases the obstruction of rotation of the drive shaft 5.

Such a pole lock 9 is oscillated by the operating mechanism 11.

The operating mechanism 11 includes a rotating shaft 51, a rotating member 53, an urging member 55, a rod 13, a sleeve 15, and a sleeve guide 17.

The rotary shaft 51 is rotatably supported by the side wall of the casing 3 through the side wall of the casing 3.

An actuator (not shown) composed of an electric motor attached to the outside of the casing 3 is connected to an end of the rotating shaft 51 arranged outside the casing 3.

This actuator is operated by a user such as a driver switching the shift range to rotationally drive the rotary shaft 51.

A rotating member 53 is integrally rotatably provided on the end side of the rotating shaft 51 arranged inside the casing 3.

The rotating member 53 is made of a thin plate, and rotates around the axis of the rotating shaft 51 by the rotation of the rotating shaft 51.

The rotating member 53 prevents the pole lock 9 from rotating the drive shaft 5 and the pole lock 9 from rotating the drive shaft 5 by rotating the rotating shaft 51, that is, the actuator to one side and the other side. It is rotated between the unlocked position and the unlocked position.

An engaging portion in which the cylindrical roller 61 of the urging member 55 is engaged with the rotating member 53 when the rotating member 53 is positioned at the locked position and when the rotating member 53 is located at the unlocked position. 57 and 59 are provided.

The urging member 55 includes a leaf spring, one end of which is bolted to the casing 3, and the other end of which includes a cylindrical roller 61 that is engaged with the engaging portions 57 and 59 of the rotating member 53.

In a state where the cylindrical roller 61 is engaged with the engaging portions 57 and 59, the urging member 55 applies an urging force to the rotating member 53 to regulate the rotation of the rotating member 53.

Specifically, the cylindrical roller 61 is engaged by applying an urging force to the engaging portion 57 when the rotating member 53 is located on the lock position side.

On the other hand, when the rotating member 53 is located on the unlocked position side, the cylindrical roller 61 is engaged by applying an urging force to the engaging portion 59.

In this way, the urging member 55 applies an urging force to the rotating member 53 in two stages of the locking position side and the unlocking position side of the rotating member 53, and defines the rotating position of the rotating member 53.

The rotating member 53 is provided with regulating portions 63 and 65 that are brought into contact with the contacted portions of the other split case (not shown) that is assembled to the split case 31 that constitutes the casing 3.

When the rotating member 53 rotates to the lock position side or the unlocked position side, the restricting portions 63 and 65 are brought into contact with the contacted portions of the other split cases, respectively, and the rotating member 53 is further. The rotation of the rotating member 53 is regulated, and the rotation position of the rotating member 53 is defined.

The end portion of the rod 13 is engaged with such a rotating member 53, and the rod 13 is moved in the axial direction by the rotation of the rotating member 53.

The rod 13 is arranged between the rotating member 53 and the sleeve guide 17, one end of which is engaged with the rotating member 53, and the other end of which is axially movable in the sleeve guide 17 by rotation of the rotating member 53. Is located in.

A sleeve 15 is provided at an end of the rod 13 arranged in the sleeve guide 17.

The sleeve 15 is formed in a bottomed tubular shape so as to cover the end portion of the rod 13, and is provided at the end portion of the rod 13 so as to be integrally movable with the rod 13 in the axial direction and movable on the rod 13.

The sleeve 15 is provided with a cam surface 67 that is in contact with the pole contact portion 29 of the pole lock 9 and is inclined so as to reduce the outer diameter toward the end side of the rod 13 continuously in the circumferential direction. There is.

The cam surface 67 has a large inclination angle of the first cam surface 69 located on the end side of the rod 13, and the second cam surface 71 continuous from this portion toward the opposite side of the end of the rod 13. The tilt angle is set small.

As the sleeve 15 moves, the first cam surface 69 first comes into contact with the pole contact portion 29 of the pole lock 9, and the pole lock 9 is pressed in the meshing direction between the lock portion 45 and the gear member 7. The lock portion 45 and the gear member 7 are engaged with each other.

Next, due to the further movement of the sleeve 15, the second cam surface 71 comes into contact with the pole contact portion 29 of the pole lock 9, and the pole lock 9 is gradually pressed in the meshing direction between the lock portion 45 and the gear member 7 to gradually press the lock portion. The meshing state between the 45 and the gear member 7 is maintained.

The sleeve 15 is in contact with a spring 47, which is a waiting mechanism arranged on the outer periphery of the rod 13, so that the lock portion 45 and the gear member 7 can be stably meshed with each other.

Such a sleeve 15 is housed in the sleeve guide 17, and the movement of the sleeve 15 is guided.

The sleeve guide 17 is fixed to the casing 3 by fastening bolts 73 to the two fixing portions 27, respectively.

The sleeve guide 17 is provided with a support hole 75 through which the end of the sleeve 15 is inserted, and supports the end of the sleeve 15 in a movable manner.

Such a sleeve guide 17 includes a regulation wall 19 and a side wall 21.

The regulation wall 19 is arranged so as to face the pole contact portion 29 of the pole lock 9 in the swing direction of the pole lock 9 with the sleeve 15 interposed therebetween.

The regulation wall 19 is formed in a plane so as to be parallel to the direction orthogonal to the swing direction of the pole lock 9.

Such a regulation wall 19 is provided with a guide surface 77 inclined at an inclination angle similar to that of the first cam surface 69 of the sleeve 15.

The guide surface 77 first comes into contact with the first cam surface 69 of the sleeve 15 due to the movement of the sleeve 15, moves the sleeve 15 in the pressing direction of the pole lock 9, and then ends the second cam of the sleeve 15. The sleeve 15 is held in a moved state in contact with the surface 71.

By contacting the sleeve 15, such a regulation wall 19 restricts the movement of the sleeve 15 in the direction opposite to the pressing direction of the pole lock 9.

Here, the pole contact portion 29 of the pole lock 9 is formed in a plane so as to be parallel to the direction orthogonal to the swing direction of the pole lock 9, similarly to the regulation wall 19.

By forming the pole contact portion 29 and the regulation wall 19 in this way, when the sleeve 15 comes into contact with the regulation wall 19 and the pole contact portion 29, the sleeve 15 intersects the swing direction of the pole lock 9. It is possible to regulate the movement of the vehicle in a tilted direction.

In addition, by forming the pole contact portion 29 on a plane parallel to the regulation wall 19, it is possible to prevent the pole lock 9 from rattling and swinging.

Further, since the pole lock 9 is arranged in a gap set in parallel and uniformly by the plane of the regulation wall 19 and the pole lock 9 in the front-rear direction in the swing direction, the pole lock 9 can be reliably operated in the swing direction. This makes it possible, and even if a minute vibration is input in the direction orthogonal to the swing direction of the pole lock 9, the pole lock 9 is prevented from operating in an unexpected direction due to the vibration, and uneven wear or striking is performed on the surface of the pole lock 9. It is possible to prevent scars from being generated.

The configurations of the one side wall 21 and the other side wall 23 and their respective functions are as follows.

The one side wall 21 is formed of one member continuous with the regulation wall 19 so that the angle between one end of the regulation wall 19 and the regulation wall 19 is a right angle.

The one side wall 21 is arranged on one side of the sleeve 15 in a direction orthogonal to the swing direction of the pole lock 9, and is flat so that the surface facing the sleeve 15 is parallel to the swing direction of the pole lock 9. Is formed of.

When the sleeve 15 tries to move to one side in the direction orthogonal to the swing direction of the pole lock 9, the one side wall 21 comes into contact with the sleeve 15 and restricts the movement of the sleeve 15 to one side in the orthogonal direction. Then, the sleeve 15 is guided in the swing direction of the pole lock 9.

At this time, since the one side wall 21 is formed of a flat surface, it is possible to stably guide the movement of the pole lock 9 of the sleeve 15 in the swing direction.

The other side wall 23 provided in the casing 3 is arranged on the side facing the one side wall 21 with the sleeve 15 interposed therebetween.

The other side wall 23 is provided on the casing 3 and is arranged on the other side of the sleeve 15 in a direction orthogonal to the swing direction of the pole lock 9.

The other side wall 23 is formed in a flat surface so that the surface facing the sleeve 15 is parallel to the swing direction of the pole lock 9.

When the sleeve 15 tries to move to the other side in the direction orthogonal to the swing direction of the pole lock 9, the other side wall 23 comes into contact with the sleeve 15 and restricts the movement of the sleeve 15 to the other side in the orthogonal direction. Then, the sleeve 15 is guided in the swing direction of the pole lock 9.

At this time, since the other side wall 23 is formed of a flat surface, the movement of the pole lock 9 of the sleeve 15 in the swing direction can be stably guided.

By providing the other side wall 23 in the casing 3 in this way, the regulation wall 19 and the one side wall 21 may be provided on the sleeve guide 17, and the shape of the sleeve guide 17 can be simplified.

Therefore, the sleeve guide 17 can be easily processed, and the manufacturing cost of the sleeve guide 17 can be reduced.

Such a sleeve guide 17 is provided with a contact portion 25 that restricts the sleeve guide 17 from moving in the direction opposite to the pressing direction of the pole lock 9 of the sleeve 15.

The contact portion 25 is provided on the surface of the regulation wall 19 opposite to the side on which the guide surface 77 is provided, and is formed in a plane so as to be parallel to the direction orthogonal to the swing direction of the pole lock 9. ..

The contact portion 25 is brought into contact with the contacted portion 79 provided on the casing 3 in a state where the sleeve guide 17 is assembled to the casing 3 via the two fixing portions 27.

When the sleeve 15 comes into contact with the pole contact portion 29 of the pole lock 9 and a reaction force is input to the sleeve guide 17 in the direction opposite to the pressing direction of the pole lock 9, the contact portion 25 has a reaction force. Is received by contact with the contacted portion 79 of the casing 3.

Here, when the sleeve guide 17 is not provided with the contact portion 25, when a reaction force to the side opposite to the pressing direction of the pole lock 9 is input to the sleeve guide 17, the reaction force is transmitted by the fixing portion 27. Will receive.

Therefore, in the conventional sleeve guide, in order to sufficiently receive this reaction force, in addition to fastening the bolt 73, a high-rigidity knock pin for positioning the sleeve guide 17 with respect to the casing 3 is used, and the fixed structure is fixed. The cost was high.

On the other hand, by providing the abutting portion 25 on the sleeve guide 17, the reaction force input to the sleeve guide 17 can be received by the casing 3, and the fixing structure of the sleeve guide 17 is fixed by fastening the bolts 73. The fixed portion 27 can be used, and the cost can be reduced.

In such a park lock device 1, the sleeve guide 17 has a regulation wall 19 that restricts the movement of the sleeve 15 in the direction opposite to the pressing direction of the pole lock 9, and a direction orthogonal to the pressing direction of the pole lock 9 of the sleeve 15. Since one side wall 21 for restricting the movement to one side is provided, the regulation wall 19 and the one side wall 21 of the sleeve guide 17 allow the sleeve 15 to move in the direction opposite to the pressing direction of the pole lock 9 and the sleeve. It is possible to regulate the movement of the pole lock 9 of 15 to one side in the direction orthogonal to the pressing direction.

Further, since the casing 3 is provided with the other side wall 23 that regulates the movement of the sleeve 15 to the other side in the direction orthogonal to the pressing direction of the pole lock 9, the other side wall 23 of the casing 3 causes the sleeve 15 to move. It is possible to restrict the movement of the pole lock 9 in the direction orthogonal to the pressing direction to the other side.

Therefore, in such a park lock device 1, the movement of the sleeve 15 can be restricted without making the sleeve guide 17 a complicated shape that covers the periphery of the sleeve 15, and the cost of the sleeve guide 17 can be reduced. be able to.

Further, since the sleeve guide 17 is provided with a contact portion 25 that comes into contact with the casing 3 and restricts the sleeve guide 17 from moving in the direction opposite to the pressing direction of the pole lock 9 of the sleeve 15, the sleeve guide 17 is provided. An external force applied to the casing 3 in the direction opposite to the pressing direction can be received by the casing 3 via the contact portion 25.

Further, since the sleeve guide 17 is fixed to the casing 3 via at least two fixing portions 27, the fixing structure of the sleeve guide 17 to the casing 3 can be simplified.

Further, since the regulation wall 19, the one side wall 21 and the other side wall 23 are each formed on a flat surface, the sleeve 15 can be moved stably without rattling when the sleeve 15 moves.

Therefore, the swing of the pole lock 9 due to the pressing of the sleeve 15 can be stabilized, and the rotation blocking function and the rotation blocking releasing function of the drive shaft 5 due to the swing of the pole lock 9 can be stabilized.

Further, since the pole contact portion 29 of the pole lock 9 that comes into contact with the sleeve 15 is set in shape so as to be parallel to the regulation wall 19, the swing of the pole lock 9 can be further stabilized.
