The retaining piece portion 21 is rotatably attached to the base bracket 2 by preventing the shaft member 4 from coming off from the shaft support hole 2j in the engaged state with the engaging piece portion 4b.

  A pair of guide mounting holes 2m are formed in the upper wall surface 2a of the base bracket 2, and a pair of mounting claws 9b provided in the plunger guide 9 are engaged with the pair of guide mounting holes 2m, respectively. The plunger guide 9 is attached to the upper wall surface 2a. In addition, the front wall surface 2h and the rear wall surface 2i of the base bracket 2 are formed with mounting work holes 2n for mounting the support shaft 6 for connecting the shaft member 4 to the shift lever 3 in the accommodation space 2d.

  Next, an assembly procedure when the shift lever 3 is assembled to the base bracket 2 by the shaft member 4 will be described with reference to FIGS.

Further, the shaft portion 4a is disposed so as to be rotatable about the axis C between the upper end 3f of the coupling cutout portion 3c of the lever main body portion 3b and the contact surface portion 3e.

  In the state shown in FIG. 4, the left and right arc portions of the shaft portion 4a whose outer diameter is the diameter 2R as it is without the connection surface 4c being formed are located on the left and right side surfaces 3d above the contact surface 3e. In other words, the left and right arc portions of the shaft portion 4a are arranged in the left-right direction with the axis C as the center. As a result, the width dimension of the shaft member 4 in the state shown in FIG. 4 becomes the diameter dimension 2R and is larger than the width dimension W between the left and right contact surface portions 3e. For this reason, the left and right contact surface portions 3e of the lever main body portion 3b interfere with the left and right arc portions of the shaft portion 4a, so that the shaft member 4 cannot be lifted up by the shift lever 3.

  Next, as shown in FIG. 5, the shaft member 4 is rotated by 90 ° about the axis C with the shaft portion 4 a disposed between the upper end 3 f of the connection notch 3 c and the contact surface portion 3 e. As a result, the longitudinal direction of the engagement piece portion 4b coincides with the left-right direction, so that the engagement piece portion 4b is engaged with the retaining piece portion 21, that is, the shaft member 4 is retained from the shaft support hole 2j. It becomes a state.

Included). For this reason, the left and right contact surface portions 3e of the lever main body portion 3b do not interfere with the left and right connecting surfaces 4c of the shaft portion 4a, and the shift lever 3 can be pulled up.

  Next, as shown in FIG. 6, the left and right contact surface portions 3 e of the lever main body portion 3 b are individually brought into contact with the left and right connection surfaces 4 c of the shaft member 4 by pulling up the shift lever 3. At this time, the left and right second shaft insertion holes 3g formed in the shift lever 3 are in communication with the first shaft insertion holes 4d formed in the shaft member 4, respectively.

  Then, as shown in FIG. 7, the support shaft 6 through the mounting work hole 2n of the base bracket 2 is inserted into the first and second shaft insertion holes 4d and 3g in a communicating state, and comes out at the tip portion thereof. The shaft member 4 is connected to the shift lever 3 by attaching the push nut 6b for stopping. Thereby, the shift lever 3 is assembled to the base bracket 2 via the shaft member 4.

  On the other hand, in the assembling procedure B, as shown in FIG. 8, the lever main body 3b of the shift lever 3 is obliquely accommodated in the accommodating space 2d of the base bracket 2, and the shaft member 4 is moved to the left and right side wall surfaces 2f, 2g. Is inserted into the shaft support hole 2j. At this time, the shaft member 4 is in a state in which the engagement piece portion 4b formed in a rounded rectangular shape is released from the engagement with the retaining piece portion 21 by matching the longitudinal direction with the vertical direction. Further, the reduced diameter portion 4g is disposed between the left and right contact surface portions 3e, in other words, the reduced diameter portion 4g is sandwiched between the left and right contact surface portions 3e. In addition, the shaft member 4 is in a state of being rotatable about its axis C by sandwiching the reduced diameter portion 4g between the left and right contact surface portions 3e in this way.

  Next, as shown in FIG. 9, the shaft member 4 is rotated 90 ° about the axis C from the state where the reduced diameter portion 4 g is sandwiched between the left and right contact surface portions 3 e. As a result, the longitudinal direction of the engagement piece portion 4b coincides with the left-right direction, so that the engagement piece portion 4b is engaged with the retaining piece portion 21, that is, the shaft member 4 is retained from the shaft support hole 2j. It becomes a state.

  Next, as shown in FIG. 10, the shift lever 3 housed in the housing space 2 d is shifted to an upright state in an oblique state. In other words, the left and right contact surface portions 3e that are sandwiched between the reduced diameter portions 4g of the shaft member 4 are moved toward the first shaft insertion hole 4d along the axis C direction. Thereby, the left and right contact surface portions 3e are in contact with the left and right connection surfaces 4c of the shaft member 4, respectively, and the left and right second shaft insertion holes 3g formed in the shift lever 3 are respectively The shaft member 4 is in communication with the first shaft insertion hole 4 d formed in the shaft member 4.

  Then, as shown in FIG. 11, the support shaft 6 that has passed through the mounting work hole 2n of the base bracket 2 is inserted into the first and second shaft insertion holes 4d and 3g that are in communication with each other, and is pulled out to the tip portion. The shaft member 4 is connected to the shift lever 3 by attaching the push nut 6b for stopping. Thereby, the shift lever 3 is assembled to the base bracket 2 via the shaft member 4.

  As described above, the shift lever device 1 of the present embodiment is rotatably supported by the pair of shaft support holes 2j of the base bracket 2 fixed to the vehicle at both ends of the shaft member 4 connected to the shift lever 3. Thus, in the shift lever device 1 in which the shift lever 3 is swingably attached to the vehicle, the shift lever 3 is integrated with the shaft-shaped rod portion 3a operated by the driver and the base portion of the rod portion 3a. The base bracket 2 is provided with left and right side wall surfaces 2f, 2g each having a pair of shaft support holes 2j, and the shaft member 4 is provided with the shaft portion 4a. A hook-like engagement piece 4b integrally provided at one end of the shaft portion 4a, and the shaft portion 4a is flat on the left and right side portions around the axis C of the shaft member 4. surface The left and right connecting surfaces 4c, which are formed in the shape of the shaft member 4 and have the same distance from the axial center C of the shaft member 4 and smaller than the radial dimension R of the shaft portion 4a, and the left and right connecting surfaces 4c And a first shaft insertion hole 4d that is formed in a direction orthogonal to the axis C of the shaft member 4 and through which the support shaft 6 is coupled to the shaft member 4 to connect the lever main body portion 3b. The lower portion of the portion 3b is provided with a connection notch portion 3c that is formed by cutting out in the vertical direction with a width dimension substantially the same as the diameter size 2R of the shaft portion 4a and connecting the shaft member 4. The left and right side surfaces 3d forming the portion 3c are formed so as to protrude from the upper end 3f of the connection notch 3c downward from the upper end 3f by a predetermined dimension H so as to narrow the width of the connection notch 3c. The left and right contact surface portions 3e that individually contact the connection surface 4c, and the right and left contact surface portions 3e and the left and right connecting surfaces 4c that are formed in a direction orthogonal to the left and right contact surface portions 3e In this state, a second shaft insertion hole 3g that is inserted through and attached to the support shaft 6 by communicating with the first shaft insertion hole 4d is provided, and the predetermined dimension H is such that the shaft portion 4a is connected to the connection notch portion 3c. The shaft member 4 is set to a dimension that allows the shaft member 4 to rotate about its axis C in a state of being arranged between the upper end 3f and the contact surface portion 3e. A shaft support hole 2j is rotated around the outer wall of the side wall surface 2f. The shaft member 4 can be engaged with and released from the engagement piece 4b by rotating the shaft member 4 as the center of movement, and the shaft member 4 can be removed from the shaft support hole 2j in the engaged state with the engagement piece 4b. Detachment piece 2 which is attached to the base bracket 2 so as to be prevented from coming off and pivoted. l is provided.

  Thus, the shaft member 4 is provided with the left and right connecting surfaces 4c set to a size smaller than the radial size of the shaft portion 4a, and the left and right connecting portions 3c formed in the lever body 3b of the shift lever 3 are connected to the left and right. By providing the left and right contact surface portions 3e that individually contact the surface 4c, the shaft member 4 is disposed in a state in which the shaft member 4 is disposed in the connection cutout portion 3c (between the left and right side surfaces 3d forming the connection cutout portion 3c). It can be turned. For this reason, when the shift lever 3 is assembled to the base bracket 2 via the shaft member 4, the shaft member 4 is rotated and the shift lever 3 is moved from the state in which the shaft member 4 is disposed in the connection notch 3c. Since the connecting surface 4c and the contact surface portion 3e can be brought into contact with each other easily, the assembly work can be facilitated after improving the assembly accuracy of the shaft member 4 and the shift lever 3 by surface contact. . Then, a hook-like engagement piece 4b is integrally provided at one end of the shaft portion 4a constituting the shaft member 4, and the engagement piece is formed on the outer wall of the side wall surface 2f of the base bracket 2 by rotating the shaft member 4. By providing the retaining piece portion 21 that enables the engagement with the portion 4 b and the release thereof, a structure for preventing the shaft member 4 from coming off can be configured between the shaft member 4 and the base bracket 2. Therefore, it is not necessary to separately provide a component for preventing the shaft member 4 from being detached (for example, a plate member), and the number of components can be reduced.

  The shaft member 4 is formed as a reduced diameter portion 4g having a base portion on the side of the engagement piece portion 4b smaller than the diameter size 2R of the shaft portion 4a. The diameter size of the reduced diameter portion 4g is determined by the left and right contact surface portions. By setting the horizontal width dimension 3e or less between 3e, it becomes possible to arrange the reduced diameter portion 4g between the left and right contact surface portions 3e. As a result, the lever main body portion 3b is accommodated obliquely in the accommodating space 2d so that the reduced diameter portion 4g is sandwiched between the left and right contact surface portions 3e, and the shift lever 3 is assembled to the base bracket 2 from this state. Attached procedure B becomes possible.

  On the rear end surface of the engagement piece 4b, an engagement recess 4e is formed that engages with a rotation jig (for example, a minus driver) for rotating the shaft member 4 with the shaft support hole 2j as a rotation center. The Thereby, it is possible to easily perform the retaining operation of the shaft member 4 that engages the engaging piece portion 4b of the shaft member 4 with the retaining piece portion 21 of the base bracket 2.

  Shift position holding means (plunger 7, spring 8, and plunger guide 9) for holding the shift lever 3 at the shift position by applying a biasing force to the shift lever 3 is provided. Thereby, since the shift lever 3 can be reliably stopped at each shift position, it is possible to prevent the shift position of the shift lever 3 from being erroneously changed by applying an unexpected force to the shift lever 3.

  Although the embodiment of the present invention has been described above, this is merely an example, and the present invention is not limited thereto, and various modifications can be made without departing from the scope of the claims. . For example, in the configuration in the embodiment, the shaft member 4 is provided with the reduced diameter portion 4g. However, the configuration is not necessarily limited to the shaft member 4 provided with the reduced diameter portion 4g.
