Abstract

[Problem] To provide a fitting structure which is configured so that the easiness of mounting of a shaft body fitting part to a main shaft body is sufficiently improved. [Solution] This fitting structure is configured in such a manner that a front end sloped surface is formed at the front end of a main shaft body so as to obliquely intersect the axis of the main shaft body. This eliminates the need for aligning a fitting hole and the main shaft body with each other before starting fitting work, and the front-most end of the main shaft body can be easily passed through the fitting hole by only roughly matching the positions of the front-most end of the main shaft body and the fitting hole. Once the front-most end of the main shaft body has been inserted into the fitting hole, the edge of the front end sloped surface of the main shaft body does not butt against the edge of the fitting hole in the process of subsequent fitting work. As a result of this configuration, the work is not hindered, and the easiness of mounting of the shaft body fitting part to the main shaft body is sufficiently improved.

[Invention of Claim 1]
According to the invention of claim 1, since the tip inclined surface which diagonally crosses the central axis of the main shaft is formed at the tip of the main shaft, the fitting hole and the main shaft can be inserted before the fitting operation is started. It is not necessary to align the center of the main shaft, and it is easy to fit the front end of the main shaft simply by aligning the fitting hole with the front end of the main shaft sufficiently smaller than the cross section of the main shaft. It can be passed through the hole. Then, if even the leading end portion of the main shaft can be inserted into the fitting hole, the edge of the tip sloped surface of the main shaft abuts against the edge of the fitting hole even in the process of the subsequent fitting operation Since work is not delayed, the assembling workability of the shaft fitting part to the main shaft can be sufficiently improved.

[Invention of claim 2 and 3]
According to the invention of claim 2, when the first case component and the second case component are united, the first main component protruding from the first case component and having a tip-opened cylindrical main shaft is first Since the support shaft having a double-supported structure is formed by the engagement of the cross-sectionally circular sub-shafts projecting from the two-case structure, the support state of the shaft-interposed parts is stabilized. In particular, as in the invention of claim 3, when the pivoting lever, which is biased in one direction by the torsion coil spring, is supported as the shaft fitting part, a load is applied to the support shaft, but the load is applied to the load. The spindle will have sufficient strength. Moreover, at the time of fitting work of the main shaft and the sub shaft, there is a possibility that the main shaft is covered by the second case structure and it becomes difficult to visually recognize, but even in such a case, the tip of the main shaft is inclined Since the surface is provided, the fitting operation of the main shaft and the sub shaft can be easily performed.

The door lock device 10 is disposed inside the door 101 in a state where the sheet metal cover 93 is disposed on the inner surface of the end wall 101A of the door 101 and the second resin cover 92 is opposed to the interior wall side of the door 101 See Figure 5). Then, the bolt passed through the through hole provided in the end wall 101 A of the door 101 is tightened to the screw hole N 3 (see FIG. 1A) of the sheet metal cover 93 to fix the door lock device 10 to the door 101. Further, as shown in FIG. 1B, the striker receiving groove 12 of the door lock device 10 is superimposed on the notch groove 101B provided in the door 101. Then, the striker 15 provided on the inner surface of the door frame 100W of the vehicle 100 main body enters the striker receiving groove 12 from the striker receiving port 12K when the door 101 is closed.

As shown in FIG. 12, the latch 13 has first and

second locking claws

13A and 13B parallel to each other, and a striker is received between the first and

second locking claws

13A and 13B. It becomes part 13C. Then, a pivoting support pin 13J described above passes through a portion connecting the first and

second locking claws

13A and 13B in the latch 13.

Further, the latch 13 is biased in the unlatching direction (clockwise direction in FIG. 12) by a torsion coil spring (not shown) provided between the latch 13 and the resin body 11. Then, when the door 101 is opened, the latch 13 is positioned at the unlatched position (the position shown in FIG. 12) by the abutment between the stopper abutting portion 13D provided in the latch 13 and the stopper 11X provided in the resin body 11. Be done.

In the unlatched position, the first locking claw 13A retracts above the striker receiving groove 12 and the second locking claw 13B crosses the striker receiving groove 12 so that the open end of the striker receiving portion 13C is a striker. It faces the striker receiving port 12 K side of the receiving groove 12. Then, the striker 15 entering the striker receiving groove 12 is received in the striker receiving portion 13C, and the striker 15 pushes the second locking claw 13B to turn the latch 13 in the latch direction (counterclockwise direction in FIG. 12). Move. As a result, as shown in FIG. 13, the striker receiving port 12 K side of the striker receiving groove 12 from the striker receiving groove 12 is closed by the first locking claw 13 A, and the latch 13 is engaged with the striker 15.

As described above, the ratchet 14 is rotatably supported by the rotation support pin 14J, and has the latch rotation restriction piece 14A and the stopper piece 14B protruding in opposite directions. Further, the ratchet 14 is biased in the counterclockwise direction in FIG. 12 by the torsion coil spring 14S. Thus, the ratchet 14 is normally positioned at the home position where the stopper piece 14B is in contact with the ratchet stopper 11D provided on the resin body 11. At this home position, the latch rotation restricting piece 14A of the ratchet 14 interferes with the first locking claw 13A and the second locking claw 13B of the latch 13, and the ratchet 14 rotates clockwise from the home position and releases When it reaches the position, the latch rotation restricting piece 14A of the ratchet 14 and the first locking claw 13A and the second locking claw 13B of the latch 13 do not interfere with each other. In addition, as shown in FIG. 4, the base end part of the spindle 97 mentioned later has penetrated the inner side of the coil part of the torsion coil spring 14S.

When the door 101 is closed from the open state, the ratchet 14 engages with the latch 13 as follows. That is, when the door 101 is closed, the second locking claw 13B and the first locking claw 13A of the latch 13 which are turned by being pushed by the striker 15 sequentially depress the latch rotation restriction piece 14A of the ratchet 14 pass. Then, when the door 101 reaches a position where the soundproof member 101C (see FIG. 1B) between the door frame 100W and the door frame 100W is maximally crushed, the latch 13 receives the second locking from the latch rotation restricting piece 14A of the ratchet 14. The claws 13B reach the slightly separated overstroke position, whereby the ratchet 14 returns to the home position. Then, when the door 101 is pushed back by the elastic force of the soundproof member 101C, the latch rotation restricting piece 14A of the ratchet 14 abuts against the first locking claw 13A of the latch 13 from the opposite side of the striker receiving portion 13C. 13 is positioned in the latch position. As a result, the rotation of the latch 13 in the latch releasing direction is restricted, and the door 101 is held in the fully closed state.

The rotation restriction of the latch 13 by the ratchet 14 is either the outside door handle 104 provided on the exterior surface of the door 101 shown in FIG. 1B or the inside door handle (not shown) provided on the interior surface (inner surface) of the door 101.

The outside open lever 17 is restricted in its rotation range as the upper edge of the operating arm 17D abuts against a stopper 90S (see FIGS. 7 and 8) integrally formed on the resin body 90. It pivots between the home position shown in FIG. 14A and FIG. 14B and the operating position (see FIGS. 15A and 15B) rotated clockwise by a predetermined angle from the home position. In addition, when the outside open lever 17 is disposed at the origin position, the support arm 17A is inclined downward to the front (see FIG. 14A), and when the outside open lever 17 is in the operation position, the support arm 17A is horizontally oriented. And slightly inclined forward and downward (see FIG. 15A).

Furthermore, the outside open lever 17 is biased toward the origin by the torsion coil spring 18 (see FIGS. 4, 6 and 14A) loosely fitted to the outside of the support projection 95 (support shaft 97). . Specifically, the outside open lever 17 has a locking projection 17X bent at a right angle in a direction parallel to the support shaft 97, and one spring end projecting laterally from the coil portion 18C of the torsion coil spring 18 The portion is locked to the locking projection 17X, and the other spring end portion is locked to the upper surface of the stopper portion 90S (see FIG. 7). The torsion coil spring 18 corresponds to the “shaft fitting part” in the present invention.

At the front end portion of the support arm 17A, an engagement hole 17B is penetratingly formed in a direction parallel to the axial direction of the support shaft 97. The engagement hole 17B has a shape in which a pair of

chevrons

17T and 17T project toward the side approaching each other from two positions 180 degrees apart on the inner circumferential surface.

The pressure receiving piece 17C is bent and protrudes from the lower edge of the front end of the support arm 17A. Then, when the inside door handle is operated, the inside open lever 20 described later abuts on the pressure receiving piece 17C from below to turn the outside open lever 17 from the home position to the operating position.

As shown in FIG. 6, from the upper edge of the rear end of the operation arm 17D, the engagement portion 17E is bent at a right angle and protrudes toward the sheet metal cover 93 side. A through hole is formed in the engaging portion 17E, and the resin ring 17V is attached to the through hole. Further, one end of a rod (not shown) is connected to the inside of the resin ring 17V, and the other end of the rod is connected to the outside door handle 104. Then, when the outside door handle 104 is operated, the engaging portion 17E is pushed downward, and the outside open lever 17 rotates from the home position to the operating position.

As shown in FIG. 14A, the engagement protrusion 19A of the open link 19 is rotatably engaged with the engagement hole 17B of the outside open lever 17. The open link 19 has a shape extending in the vertical direction as a whole, and the engagement protrusion 19A described above protrudes in the axial direction of the support shaft 97 from the lower end. The open link 19 is restricted in its rotation range by the pair of

chevrons

17T and 17T in the engagement hole 17B, and it is between the unlock position which has fallen to the front and the lock position which has fallen to the rear. Rotate. In addition, a torsion coil spring 29 (not shown in FIGS. 14B, 15A and 15B) is provided between the open link 19 and the outside open lever 17, and the open link 19 is unlocked by the torsion coil spring 29. It is biased by

From the upper edge of the open link 19, a push-up projection 19 C is bent in the axial direction of the support shaft 97 and protrudes. When the open link 19 is disposed at the unlock position, as shown in FIG. 14B, the push-up projection 19C is positioned below the tip contact portion 16B of the lift lever 16, and in this state the outside open lever 17 When the lever pivots from the home position to the actuation position, as shown in FIG. 15B, the push-up projection 19C pushes up the tip contact portion 16B of the lift lever 16. As a result, the lift lever 16 pivots from the home position to the release position together with the ratchet 14 (see FIG. 13), the engagement between the ratchet 14 and the latch 13 is released, and the door 101 is opened.

On the other hand, when the open link 19 is disposed at the lock position, as shown in FIG. 14A, the push-up protrusion 19C is displaced to the rotation support pin 14J side from the tip contact portion 16B of the lift lever 16. Therefore, even if the outside open lever 17 pivots from the home position to the working position in this state, the lifting projection 19C does not push up the tip contact portion 16B of the lift lever 16 as shown in FIG. 15A. That is, when the open link 19 is disposed in the lock position, the door 101 can not be opened even if the outside door handle 104 is operated.

A lower end arm 19F protrudes forward from a lower end position of the open link 19, and an unlocking piece 19B is bent in the axial direction of the support shaft 97 and protrudes forward from the lower edge portion of the lower end arm 19F. Then, the open link 19 is switched from the unlock position to the lock position by pushing the lock release piece 19B upward by an active lever 25 described later.

The inside open lever 20, the active lever 25, the connecting bar 30, the relay lever 31 and the like shown in FIG. 16 are housed in the second component housing portion 90B of the resin body main body 90 described above. Hereinafter, in the description of each part, the surface facing the second resin cover 92 (the surface facing the front side of the sheet of FIG. 16) is referred to as the "outside" of the part, and the opposite side is the part "Inside" of the.

The inside open lever 20 is rotatably supported by a support shaft 20J disposed at a position closer to the lower end on the right side in FIG. 16 of the second component storage unit 90B. The support shaft 20J is formed by fitting a shaft having a circular cross section and a cylindrical body protruding from the back surface of the second component storage portion 90B and the back surface of the second resin cover 92. The same applies to

spindles

24J and 25J described later. Further, in the inside open lever 20, a push-up contact portion 20B which extends from the support shaft 20J toward the central side in the lateral direction of the resin body 11 and whose tip is bent in the axial direction of the support shaft 20J A connecting projection 20C is provided, which protrudes downward from the portion 20B and whose tip is a wire locking portion 20A. Further, the inside door handle is connected to the wire locking portion 20A via a wire (not shown). Then, by operating the inside door handle, the inside open lever 20 is pivoted from the home position to the working position, during which the push-up abutment portion 20B of the inside open lever 20 pushes up the pressure receiving piece 17C of the outside open lever 17 described above. The outside open lever 17 also pivots from the home position to the operating position. At this time, if the open link 19 is disposed at the unlock position, the door 101 is opened as described above, and if the open link 19 is disposed at the lock position, the door 101 is not opened.

The active lever 25 is rotatably supported by a support shaft 25J located at the center in both the vertical and horizontal directions in the second component storage unit 90B. The active lever 25 has a first fan-shaped projection 25A projecting upward from the support shaft 25J, a sector-shaped second sector-shaped projection 25D extending obliquely downward to the left from the support shaft 25J, and a diagonal right side from the support shaft 25J. And a projecting active acting arm 25C.

As shown in FIG. 16, the tip of the active action arm 25C is opposed to the unlocking piece 19B of the open link 19 from below. Then, when the active lever 25 pivots from the unlock position to the lock position, as shown in the changes in FIG. 14B to FIG. 14A, the active action arm 25C pushes up the unlocking piece 19B to unlock the open link 19. Move from to the lock position.

As shown in FIG. 16, the wire connection piece 25E protrudes from the lower end of the second fan-shaped projection 25D. A lock operating portion provided on the inner surface of the door 101 is connected to the wire connection piece 25E via a wire (not shown). Then, by operating the lock operation unit, the active lever 25 can be switched between the unlock position and the lock position.

The active lever 25 can be switched between the unlock position and the lock position by means of the in-vehicle centralized lock or the wireless key 108 (see FIG. 1B) as well as the lock operation portion on the inner surface of the door 101. For that purpose, the motor 22 shown in FIG. 16 is attached to the resin body 11. A worm gear 23 is fixed to a rotational output shaft of the motor 22 and a worm wheel 24 meshing with the worm gear 23 is rotatably supported on a support shaft 24 J provided on the resin body main body 90. Then, a pair of rotation pressing protrusions 24A provided on the worm wheel 24 (only one rotation pressing protrusion 24A is shown in FIG. 16) and unevenness (not shown) provided on the inner surface of the first sector protrusion 25A. By engaging with the part, the power of the motor 22 can be transmitted to the active lever 25 to switch the active lever 25 between the locked position and the unlocked position.

The active lever 25 can also be switched between the unlock position and the lock position by inserting the key 103 (see FIG. 1B) into the key cylinder 102 provided in the door 101 and performing key operation. As shown in FIG. 1A, the key connecting lever 32 connected to the key cylinder 102 is disposed on the back side of the resin body main body 90, and the pivoting axis passes through the resin body main body 90, as shown in FIG. Are connected to the relay lever 31 disposed in the second component storage unit 90B. The relay lever 31 and the active lever 25 are connected by a connecting bar 30. Thus, the active lever 25 is also switched between the unlock position and the lock position by the operation of the key cylinder 102.

By the way, in the door lock device 10 of the present embodiment, the support structure 97 according to the present invention is applied to the support shaft 97 that rotatably supports the outside open lever 17. The structure of the support shaft 97 will be described below.

That is, as shown in FIG. 11, from the lower end portion of the inner surface of the first resin cover 91, the support projection 95 protrudes toward the back wall 90C (the front side of the sheet of FIG. 11) of the first component storage portion 90A. . As shown in FIG. 4, the support projection 95 includes a first cylindrical portion 95A protruding from the first resin cover 91, and a second cylindrical portion 95C protruding from a tip wall 95B closing the tip of the first cylindrical portion 95A. And have. Further, the second cylindrical portion 95C is disposed at a position eccentric downward with respect to the center of the first cylindrical portion 95A. The coil portion of the torsion coil spring 14S is loosely fitted to the outside of the first cylindrical portion 95A.

As shown in FIG. 10, a pivoting support cylinder 96 (corresponding to the “main shaft” of the present invention) is formed in a projecting manner on the back wall 90C of the first component housing 90A in the resin body main body 90. The rotation support cylinder 96 has a cylindrical shape with an open tip, and a tip inclined surface 96F according to the present invention is formed on the open surface. As shown in FIG. 17, the pivoting support cylinder 96 has an acute-angled wedge shape (shape like the tip of a bamboo basket) whose tip is diagonally cut off with respect to the central axis J1. The whole of the open surface 96 is constituted by a flat tip inclined surface 96 F diagonally crossing the central axis J 1 of the rotation support cylinder 96. The tip opening edge of the rotation support cylinder 96 is chamfered in a tapered shape, and the tip outer peripheral edge of the rotation support cylinder 96 is R-chamfered. Note that the tip end inclined face 96F is an inclined face that constitutes the end face of the cylindrical wall of the rotation support cylinder 96, and the opening area on the inner side of the cylindrical wall is oblique to the central axis J1. Means an inclined surface composed of a virtual inclined surface crossing the

As shown in FIG. 4, a through hole 96A is formed at the center of a portion of the back wall 90C surrounded by the rotation support cylinder 96. Then, the first resin cover 91 is assembled to the resin body main body 90 in a state in which the rotation support cylinder 96 is inserted in the circular fitting hole 17H formed through the outside open lever 17 and the coil portion 18C of the torsion coil spring 18 The second cylindrical portion 95C corresponding to the “sub-shaft” of the present invention is inserted into the inside of the rotation support cylinder 96. Then, the first resin cover 91 is fixed to the resin body main body 90 by tightening the screw N2, which is a self-tapping screw inserted into the through hole 96A, into the screw lower hole 95D penetrating the center of the second cylindrical portion 95C. At the same time, the second cylindrical portion 95C and the rotation support cylinder 96 are integrated to form a support shaft 97 on which the outside open lever 17 and the torsion coil spring 18 are supported.

Note that the inner diameter of the rotation support cylinder 96 and the outer diameter of the second cylindrical portion 95C are substantially the same, and they are fitted with almost no rattling. Similarly, the outer diameter of the rotation support cylinder 96 and the inner diameter of the fitting hole 17H of the outside open lever 17 are substantially the same, and the outside open lever 17 and the rotation support cylinder 96 have almost no play. It is fitting without the condition. The fitting hole 17H may not be circular, and may be, for example, a polygon circumscribing the outer peripheral surface of the rotation support cylinder 96. The center hole of the rotation support cylinder 96 may not be circular in cross section, and may be, for example, a polygonal cross section circumscribing the outer peripheral surface of the second cylindrical portion 95C.

Here, the second cylindrical portion 95C is fitted to the inside of the rotation support cylinder 96, and the resin body main body 90 and the first resin cover 91 are integrally fixed by the screws N1 and N2. Has a double-ended structure. Due to the double-supported structure, the support shaft 97 has sufficient strength against the load from the outside open lever 17 biased by the torsion coil spring 18, and the support state of the outside open lever 17 is stable. Do.

The description regarding the structure of the door lock device 10 of this embodiment is above. Next, a method of manufacturing the door lock device 10 of the present embodiment will be described.

First, various components (see FIG. 16) such as the motor 22, the worm wheel 24, and the active lever 25 are assembled in the second component storage portion 90B of the resin body main body 90.

Next, the second resin cover 92 is put on the side opening of the second component storage section 90B, and the shaft constituting the

spindles

20J, 24J, 25J and the cylindrical body (not shown) are engaged with each other in a concavo-convex manner. The outer edge portion of the resin body main body 90 and the outer edge portion of the second resin cover 92 are superimposed on each other, and they are joined by, for example, laser welding.

Next, the outside open lever 17 in which the open link 19 and the torsion coil spring 29 are integrally assembled in advance is assembled in the first component accommodating portion 90A of the resin body main body 90. That is, the rotary support cylinder 96 projecting from the back wall 90C of the first component storage portion 90A is inserted into the inside of the circular fitting hole 17H formed in the outside open lever 17 and these are fitted. Here, in the fitting structure 200 according to the present invention, a tip inclined surface 96F obliquely crossing the central axis J1 is formed on the open surface of the tip of the rotation support cylinder 96, and the tip of the rotation support cylinder 96 has an acute angle. It is not necessary to center the fitting hole 17H and the rotation support cylinder 96 before starting the fitting operation, as shown in FIG. 17A. Position the tip end 96P of the rotation support cylinder 96, which is sufficiently smaller than the cross section thereof, in the outline (in detail, align the tip end 96P of the rotation support cylinder 96 and the fitting hole 17H in a straight line) Only by the arrangement, as shown in FIG. 17B, the foremost end 96P of the rotation support cylinder 96 can be easily passed through the fitting hole 17H. Then, as long as the foremost end 96P of the pivoting support cylinder 96 can be inserted into the fitting hole 17H, the distal end inclined surface 96F of the pivoting support cylinder 96 is engaged with the outer edge portion of the pivoting support cylinder 96 also The edge of the hole 17H may hit halfway and the work will not be delayed. Specifically, even if the centers of the rotation support cylinder 96 and the fitting hole 17H are shifted at the beginning of the fitting operation, the centers gradually approach each other in the process of the subsequent fitting operation, and finally, as shown in FIG. As shown in 17C, the rotation support cylinder 96 and the fitting hole 17H are centered.

Next, the rotary support cylinder 96 is inserted into the coil portion 18C of the torsion coil spring 18. After the insertion, the one spring end of the torsion coil spring 18 is locked to the locking projection 17X of the outside open lever 17, and the other spring end is locked to the stopper 90S of the resin body 90. . Then, the torsion coil spring 18 is twisted and the outside open lever 17 is urged to the home position where it abuts against the stopper portion 90S, and the inner surface of the coil portion 18C of the torsion coil spring 18 is the outer surface of the rotation support cylinder 96. The coil portion 18C is disposed at a position where the center of the coil portion 18C is eccentric with respect to the center of the rotation support cylinder 96 while abutting a part. At this time, the coil portion 18C is disposed so as to abut the portion of the outer peripheral surface of the rotation support cylinder 96 opposite to the tip inclined surface 96F. In other words, when the torsion coil spring 18 is assembled eccentrically to the outside of the rotation support cylinder 96, the tip inclined surface 96F is formed on the opposite side to the portion to which the inner surface of the coil portion 18C approaches. By doing this, it is possible to prevent the coil portion 18C from coming off the rotation support cylinder 96 while keeping the length of the rotation support cylinder 96 short.

Here, in the present embodiment, the outside open lever 17 is assembled on the proximal end side of the rotation support cylinder 96, and the torsion coil spring 18 is assembled on the distal end side. There is a possibility that the rotation support cylinder 96 may be lengthened. That is, since the support state of the outside open lever 17 becomes unstable when the front end inclined surface 96F is disposed inside the fitting hole 17H of the outside open lever 17, the whole front end inclined surface 96F is a fitting hole It is necessary to make it project from 17H, and the rotation support cylinder 96 becomes longer accordingly. In this respect, according to the configuration of the present embodiment, the length of the rotation support cylinder 96 can be kept short.

When the assembly of the torsion coil spring 18 is completed, the first resin cover 91 is assembled to the resin body main body 90. That is, the inner surface side (the reinforcing plate 94 side) of the first resin cover 91 is brought close to the back wall 90C of the first component storage portion 90A, and the entire inner surface side of the first resin cover 91 is in the first component storage portion 90A. And the edge of the side protruding wall 91A of the first resin cover 91 is overlapped with the edge of the second resin cover 92 from the outside. Then, the locking hole 91A1 formed in the edge of the side protruding wall 91A and the locking protrusion 92A formed in the edge of the second resin cover 92 are locked. Further, the second cylindrical portion 95C of the support projection 95 formed to project from the first resin cover 91 is inserted into the inside of the rotation support cylinder 96. As a result, the resin body 90 and the first resin cover 91 are temporarily fixed.

Here, at the time of fitting work of the rotation support cylinder 96 and the second cylindrical portion 95C, the rotation support cylinder 96 is covered with the first resin cover 91 and it becomes difficult to visually recognize, but the tip of the rotation support cylinder 96 is the tip. Since the inclined surface 96F is provided, the fitting operation between the rotation support cylinder 96, which is difficult to visually recognize, and the second cylindrical portion 95C can be performed relatively easily.

More specifically, as shown in FIG. 17C, even if the central axis of the second cylindrical portion 95C is slightly inclined with respect to the central axis J1 of the rotation support cylinder 96, the tip of the second cylindrical portion 95C is Since it can be inserted into the inside of the rotation support cylinder 96 from the tip inclined surface 96F side, the fitting operation can be easily performed as compared with the one without the tip inclined surface 96F.

After temporarily fixing the resin body main body 90 and the first resin cover 91, finally, pass the screw N1 through the through hole 90D provided in the back wall 90C of the first component housing 90A and screw the screw N1 into the screw hole of the reinforcing plate 94. The screw N2 is inserted into the through hole 96A provided on the back wall 90C and is fixed to the screw lower hole 95D of the second cylindrical portion 95C inserted inside the rotary support cylinder 96 while being fixed to 94N. Thus, the first resin cover 91 is completely fixed to the resin body 90. Further, by this fixing, the support shaft 97 is double-supported, and the support state of the outside open lever 17 and the torsion coil spring 18 is stabilized. The above is the manufacturing method of the door lock device 10.

As described above, according to the fitting structure 200 of the present embodiment, since the tip inclined surface 96F obliquely crossing the central axis J1 of the rotation support cylinder 96 is formed on the open surface of the tip of the rotation support cylinder 96, Before starting the fitting operation, it is not necessary to center the fitting hole 17H and the rotation support cylinder 96, and the tip end of the rotation support cylinder 96 sufficiently smaller than the fitting hole 17H and the cross section thereof The tip end portion 96P of the rotation support cylinder 96 can be easily passed through the fitting hole 17H simply by aligning the position 96P with the outline. The outer edge portion and the fitting hole of the tip inclined surface 96F of the turning support cylinder 96 can be inserted even in the process of the subsequent fitting work, as long as the foremost end 96P of the turning support cylinder 96 can be inserted into the fitting hole 17H. Since the operation does not get stuck due to the end of the edge 17H, the assembling workability of the outside open lever 17 with respect to the rotation support cylinder 96 can be sufficiently improved. Further, by providing the front end inclined surface 96F, the operation of fitting the second cylindrical portion 95C to the inside of the rotation support cylinder 96 can be performed relatively easily. That is, according to the present embodiment, it is possible to improve the assembling workability of the fitting parts (the outside open lever 17 and the second cylindrical portion 95C) with respect to the inside and outside of the rotation support cylinder 96.

Further, in the fitting structure in which the fitting parts are fitted and assembled to the inside and the outside of the cylindrical body as in the rotation support cylinder 96 of the present embodiment, the outer peripheral edge of the tip of the cylindrical body to improve the assembling workability. It is also conceivable to provide a truncated cone-shaped guide surface at the tip opening edge, but since these guide surfaces can be formed only within the range of the wall thickness of the cylinder wall constituting the cylinder, it can be felt by the operator It is difficult to improve the workability to some extent. On the other hand, according to the present embodiment, compared with the configuration in which only the above-described guide surface is provided, the assembling workability of the fitting component to the inside and outside of the rotation support cylinder 96 can be sufficiently improved.
