  However, the above-described support structures (1) to (3) have the following problems. That is, in the support structure of (1), a shaft is required separately from the parts and the support member, and there is a problem that the number of parts increases. Moreover, in the support structure of (2), since the notch part of the shaft part notched parallel to the axial direction is inserted into the fitting hole part, the notch part and the inner wall of the fitting hole part are inserted. There is a problem that gaps are formed and the backlash of parts is large. In the support structure (3), the elastic force of the spring attached to the shaft portion (shaft) is used to maintain the state where both shaft portions are inserted into the through holes, but the elastic force of the spring is weak. When it becomes, there exists a subject that an axial part tends to come off from a through-hole.

  The present invention has been made in view of the above problems, and in a vehicle door handle device including a component and a support member that rotatably supports the component, an increase in the number of components can be suppressed, and the component It is an object of the present invention to provide a vehicle door handle device and an assembling method thereof that can suppress shakiness and can prevent a shaft portion from coming out of a hole after assembly.

In order to solve the above problems, the present invention is a vehicle door handle device including a component and a support member that rotatably supports the component,
One of the component and the support member has a pair of shaft portions formed on the same axis, and the other has a pair of bearing portions in which insertion holes into which the shaft portions are inserted are formed,
One of the pair of bearing portions is a first bearing portion, the other is a second bearing portion, the shaft portion supported by the first bearing portion is a first shaft portion, and the shaft portion is supported by the second bearing portion. As the second shaft part,
The circumferential direction of the outer peripheral surface of the first shaft portion so that the first shaft portion can be inserted in a state where the first shaft portion is inclined obliquely with respect to the axis of the insertion hole. And a support part supporting a part of the outer peripheral surface located on the opposite side of the surface supported by the support part has a shape shifted in the axial direction of the insertion hole. And
When the component is rotated around the axis of the first shaft portion and the second shaft portion to an angle at the time of assembly of the component, which is different from when the vehicle door handle device is used. When there is a first position where both the first shaft portion and the second shaft portion are inserted into the insertion hole, and the first shaft portion is inserted into the insertion hole of the first bearing portion, Enabling movement of the component in the axial direction of the insertion hole between the two shaft portions and the second position removed from the insertion hole of the second bearing portion;
The support member and the component that restrict the movement of the component from the first position to the second position when the component is in a use state rotated to an angle during use of the vehicle door handle device. It is provided with the fitting structure formed in this.

  According to the present invention, since the pair of shaft portions are integrally formed on the component or the support member, an increase in the number of components can be suppressed as compared with the case where the shaft is provided separately from the component and the support member. One of the pair of bearing portions (first bearing portion) includes a support portion that supports a part of the outer peripheral surface of one of the pair of shaft portions (first shaft portion), and a surface that is supported by the support portion. Since the support portion for supporting a part of the outer peripheral surface located on the opposite side has a shape shifted in the axial direction of the insertion hole, the first shaft portion is inserted into the first bearing portion while the component is inclined obliquely. Can be inserted into the hole. Further, in the present invention, when the component is at an angle at the time of assembly, the first position where both shaft portions are inserted into the insertion hole and the second position where only the first shaft portion is inserted into the insertion hole. Since it has a fitting structure that allows movement between the first shaft part and the first shaft part inserted into the insertion hole of the first bearing part by tilting obliquely, the part is returned to the horizontal direction, and the part is inserted in the axial direction of the through hole. The second shaft portion can also be inserted into the insertion hole by moving to. In addition, unlike the support structure of (2) above, it is not necessary to form a notch portion that is notched parallel to the axial direction in the shaft portion, so that rattling of components can be suppressed. Further, according to the present invention, the rotation angle of the component at the time of use is different from that at the time of assembly. When the component is at the angle of use, the fitting structure formed between the component and the support member allows the first position to be changed from the first position. Since the movement of the component to the second position is restricted, it is possible to avoid the shaft portion from coming out of the insertion hole after assembly.

The vehicle door handle device assembly method of the present invention is applied to the vehicle door handle device of the present invention,
In the vehicle door handle device of the present invention, the component of the first bearing portion is in a state where the first shaft portion is obliquely inclined with respect to the axis of the insertion hole and at an angle in the assembled state. Insert the first shaft portion into the insertion hole, and then level the component so that the second shaft portion faces the insertion hole of the second bearing portion, and then be in the first position. The component is moved in the axial direction of the insertion hole, and then the component is rotated to the angle in the in-use state.

  Thereby, it is possible to obtain the same effects as the above-described effects of the vehicle door handle device of the present invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. A vehicle door handle device 1 shown in FIG. 1 is attached to a vehicle door (a front seat door or a rear seat door of a vehicle) so that a longitudinal direction of a handle member 3 to be described later faces a vehicle front-rear direction, and the vehicle door from the outside of the vehicle. It is a device for opening and closing. A vehicle door handle device 1 is made of a resin base member 2 corresponding to a support member of the present invention fixed to a vehicle door, and supported by the base member 2 so as to be rotatable about one end side as a fulcrum. A resin-made handle member 3 that performs an opening operation (in a direction away from the outer panel 100) and a closing operation opposite thereto is provided. The base member 2 is formed in an elongated shape, and is fixed to the vehicle inner side of the outer panel 100 of the vehicle door so that the longitudinal direction thereof faces the vehicle front-rear direction.

  The handle member 3 is disposed on the outer side of the vehicle with the outer panel 100 interposed therebetween, and is elongated in the longitudinal direction of the handle body 4 that is gripped by the user when the vehicle door is opened, and one end side of the handle body 4 in the longitudinal direction. And a guide arm portion 7 connected to the other end side in the longitudinal direction of the handle main body portion 4. The fulcrum arm portion 5 extends from the back surface on one end side of the handle main body portion 4 so as to be disposed in the front opening formed in the base member 2, and the handle member 3 has a short direction ( It is supported by the base member 2 so as to be rotatable around an axis 6 set in the vehicle vertical direction).

  The guide arm portion 7 extends from the back surface on the other end side of the handle main body portion 4 in the direction of the base member 2. The guide arm portion 7 is disposed in the rear opening formed in the base member 2, and is caused by the guide portion formed in the base member 2 in the rear opening as the handle member 3 is opened and closed. Reciprocates in the opposite direction. Further, a recess 8 is formed at a position near the tip of the guide arm portion 7 so that a lever 10 of a bell crank portion 9 described later is locked.

  In addition to the base member 2 and the handle member 3, the vehicle door handle device 1 includes a resin bell crank portion 9 (see FIGS. 2 to 4) and a metal counterweight portion 20 (see FIGS. 3 and 4). ) And a torsion coil spring 51 (see FIG. 3). The bell crank portion 9 has a shaft portion 12 having a circular cross section, and at one end side in the longitudinal direction of the base member 2 (side where the guide arm portion 7 is disposed), the shaft portion 12 is in the longitudinal direction of the base member 2 ( It is supported by the base member 2 so as to be rotatable around the axis L1 of the shaft portion 12 (see FIG. 2). Details of the support structure of the shaft portion 12 will be described later. In FIG. 2, the left and right directions are reversed with respect to the arrangement direction of the base member 2 in FIG. 1 (the bell crank portion 9 is on the left side of the paper surface). In FIG. 2, the illustration of the counterweight part 20 and the torsion coil spring 51 (see FIG. 3) attached to the bell crank part 9 is omitted. In FIG. 3, the bell crank portion 9, the counterweight portion 20, and the torsion coil spring 51 are viewed from the direction of FIG. 2 (the back side of the vehicle door handle device 1).

  As shown in FIGS. 2 to 4, the bell crank portion 9 includes a pair of levers 10 and 11 formed in a bell crank shape. One end of each of the levers 10 and 11 is connected to the shaft portion 12 so as to extend in the radial direction of the shaft portion 12. One lever 10 is locked in the recess 8 of the guide arm portion 7 (see FIG. 1). Accordingly, the bell crank portion 9 rotates around the axis L <b> 1 of the shaft portion 12 in conjunction with the opening / closing operation of the handle member 3.

  The other lever 11 is connected to a holding mechanism (not shown) that holds the vehicle door in a closed state. When the handle member 3 is in the closed position, the holding mechanism is in a holding state that holds the vehicle door in the closed state. In conjunction with the opening operation of the handle member 3, the bell crank portion 9 rotates, and the holding state of the holding mechanism is released when the rotation angle exceeds a predetermined angle (the vehicle door is in the open state). Will be released to allow to become). This opens the vehicle door. In this way, the bell crank portion 9 is connected to the holding mechanism so as to switch the state of the holding mechanism between the holding state and the released state according to its own rotation angle. The bell crank portion 9 corresponds to the component of the present invention.

  The counterweight portion 20 shown in FIGS. 3 and 4 serves as a mass added to the bell crank portion 9 and functions to balance inertial force at the time of a side collision. Specifically, as shown in FIG. 3, the counterweight portion 20 includes a block-shaped weight main body 21 having a weight that can become an inertial mass at the time of a side collision, and the weight main body 21 formed integrally with the weight main body 21 and laterally from the main body 21. Two leg portions 22 and 23 projecting from each other, and a stopper portion 24 formed integrally with the weight main body 21 and projecting from one end in the longitudinal direction of the main body 21. The weight main body 21, the leg portions 22, 23 and the stopper portion 24 are integrally formed by die casting, for example, so that the counterweight portion 20 can be a metal integrated part or a plurality of metal pieces instead of a single piece. It is good also as a metal body which combined and integrated.

  The leg portions 22 and 23 are formed with coaxial through holes. The shaft portion 12 is inserted into the through holes of the leg portions 22 and 23. Further, the bell crank portion 9 is formed with a protruding portion 16 that protrudes in a direction approximately opposite to the lever 10 with respect to the shaft portion 12 (see FIG. 4), and the protruding portion 16 and the stopper portion 24 come into contact with each other. ing. Both contact surfaces of the protrusion 16 and the stopper 24 are set to surfaces intersecting the rotational direction of the bell crank portion 9.

  As shown in FIG. 3, the torsion coil spring 51 is mounted on the outer periphery of the shaft portion 12 between the leg portions 22 and 23. The torsion coil spring 51 includes a spring body wound in a coil shape, extended ends hooked to the base member 2 at both ends thereof, and extended ends hooked to the counterweight portion 20. It is attached between the base member 2 and the counterweight part 20 in a state where the torsional surplus load is applied. Therefore, in FIG. 4, a torsional load that urges the counterweight portion 20 (specifically, the weight main body 21) in the clockwise direction is generated, and the stopper portion 24 is constantly pressed against the protruding portion 16 by the torsional load, and the bell crank portion 9 In response to the pressing force, it is always urged clockwise in FIG. As a result, the lever 10 is urged by the torsion coil spring 51 so as to be pressed against the lower surface of the recess 8 of the guide arm portion 7, in other words, to always pull the handle member 3 to the closed position.

  Then, after the handle member 3 is raised against the urging force of the torsion coil spring 51 and then the operating force is released, the handle member 3 is always closed by the lever 10 receiving the urging force of the torsion coil spring 51. Pulled back to position. When the lever 10 is rotated by operating the handle member 3, the bell crank portion 9 and the counterweight portion 20 are integrally rotated by the biasing force of the torsion coil spring 51. On the other hand, when a counterclockwise rotational moment (counterclockwise in FIG. 4) is generated in the counterweight portion 20, if it overcomes the spring torque of the torsion coil spring 51, the counterweight portion 20 is With the separation between the stopper portion 24 and the protruding portion 16, it can be rotated counterclockwise.

  Assuming that a side collision occurs with respect to the vehicle, the door panel and the base member 2 are about to be displaced in the collision direction with respect to the handle member 3, whereas the counterweight portion 20 tries to stop at the original position. Therefore, the lever 10 hardly rotates due to the inertia load of the counterweight portion 20. As a result, the handle member 3 is maintained in the retracted position, and the movement of the handle member 3 to the open position and thus the opening of the door is suppressed.

  Next, a support structure for the bell crank portion 9 and the base member 2 which is a feature of the present invention will be described in detail. A pair of bearing portions 30 facing each other at a distance in the longitudinal direction (vehicle longitudinal direction) of the base member 2 at a position on the rear side of the rear opening of the rear portion of the base member 2 from which the guide arm portion 7 enters, 36 is formed (see FIGS. 5 and 6). Each of the bearing portions 30 and 36 is formed with through holes 31 and 37 having the same axis L2 (see FIG. 5). An axis L2 of the through holes 31 and 37 faces the longitudinal direction of the base member 2 (vehicle longitudinal direction). Each through-hole 31 and 37 is formed in the perfect circle shape of the magnitude | size equivalent to the cross-sectional shape of the axial part 12 seeing from the front. The through holes 31 and 37 correspond to the insertion holes of the present invention.

  One bearing portion 36 is formed such that a cross-sectional line indicating the inner wall of the through hole 37 when the bearing portion 36 is cut along a plane perpendicular to the axis L2 is circular. That is, in the bearing portion 36, the lower surface support portion that supports the lower surface in the circumferential direction of the outer peripheral surface of the shaft portion 12, and the upper surface support portion that supports the upper surface of the shaft portion 12 located on the opposite side of the lower surface are the axis L2. Have the same shape in the direction.

  On the other hand, the other bearing portion 30 has a cross-sectional line indicating the inner wall of the through-hole 31 when the bearing portion 30 is cut in a plane perpendicular to the axis L2 (circular arc shape, (Semi-circular shape). That is, the bearing portion 30 has a shape in which the lower surface support portion 32 that supports the lower surface of the shaft portion 12 and the upper surface support portion 33 that supports the upper surface of the shaft portion 12 are shifted in the direction of the axis L2. In other words, the wall surface of the through hole 31 does not exist above the lower surface support portion 32, and the wall surface of the through hole 31 does not exist below the upper surface support portion 33. Furthermore, in other words, the bearing portion 30 includes a cutout portion 34 in which the upper surface facing the opposite bearing portion 36 is partially cutout and communicated with the throughhole 31, and a lower portion of the throughhole 31 in the insertion direction of the shaft portion 12. And a cutout portion 35 that is partially cut away (see FIG. 6). Furthermore, in other words, the bearing portion 30 is formed in the through-hole 31 when it is cut by a plane S1 (see FIG. 6) perpendicular to the axis L2 at a position near the entrance of the through-hole 31 (front side in the insertion direction of the shaft portion 12). When the cross-sectional line indicating the inner wall becomes a semicircular shape that protrudes downward, and is cut by a plane S2 (see FIG. 6) perpendicular to the axis L2 at the position of the outlet of the through hole 31 (the back side in the insertion direction of the shaft portion 12). The cross-sectional line indicating the inner wall of the through-hole 31 is formed in a semicircular shape protruding upward.

  The amount of deviation in the direction of the axis L2 between the lower surface support portion 32 and the upper surface support portion 33 is such that the shaft portion 12 is inclined so that the other end portion 14 of the shaft portion 12 does not hit the bearing portion 36 during assembly. Any value may be set as long as the one end portion 13 can be inserted into the through hole 31.

  The shaft portion 12 of the bell crank portion 9 is rotatably supported by both bearing portions 30 and 36. Specifically, one end portion 14 (the end portion on the side away from the levers 10, 11) of the shaft portion 12 is inserted into the through hole 37 of the bearing portion 36. On the other hand, the other end portion 13 (the end portion on the side where the levers 10 and 11 approach) of the shaft portion 12 is inserted into the through hole 31 of the bearing portion 30. Hereinafter, the bearing portion 30 is the first bearing portion, the bearing portion 36 is the second bearing portion, the end portion 13 supported by the bearing portion 30 is the first shaft portion, and the end portion 14 supported by the bearing portion 36 is the second. Sometimes called a shaft.

  The shaft portion 12 has end surfaces facing in opposite directions to each other, and a pair of shaft portions 13 and 14 of the same axis L1 and the same axis L1 as the shaft portions 13 and 14 that connect between the shaft portions 13 and 14. Intermediate shaft portion 15 (see FIG. 6). The intermediate shaft portion 15 is formed to have a diameter slightly larger than that of the second shaft portion 14 and is formed to have a diameter slightly larger than the hole diameter of the through hole 37. The counterweight part 20 and the torsion coil spring 51 described above are attached to the intermediate shaft part 15.

  The lower surface of the first shaft portion 13 on the lever 10, 11 side of the first shaft portion 13 is supported by the lower surface support portion 32, and the upper surface of a portion from the end surface of the first shaft portion 13 is the upper surface support portion 33. Are supported by the first bearing portion 30. That is, as for the 1st axial part 13, the perimeter (upper surface, lower surface) of the circumferential direction is supported by the lower surface support part 32 and the upper surface support part 33 (1st bearing part 30). Similarly, the entire circumference of the second shaft portion 14 is supported by the second bearing portion 36.

  The bell crank portion 9 is in a position (initial position) indicated by a solid line 201 in FIG. 7 when the handle member 3 is in the closed position, and when the handle member 3 is in the position at the time of the full stroke that is caused to the maximum, the bell crank portion 9 is It is in the position indicated by the dotted line 202. That is, the bell crank portion 9 rotates between the initial position 201 and the full stroke position 202 when the vehicle door handle device 1 is used. When the bell crank portion 9 is in a state of rotation angle between these positions 201 and 202 (in use state), the bell crank portion 9 is in the direction of the axis L2 of the through holes 31 and 37 (the axis L1 of the shaft portion 12). It is impossible to move.

  Specifically, as shown in FIG. 4, the bell crank portion 9 is adjacent to the base portion of the first shaft portion 13 (the portion of the shaft portion 12 to which the lever 10 and the protruding portion 16 are connected). A concave portion 17 is formed that is recessed in the direction opposite to the protruding direction of the shaft portion 13. Further, the bell crank portion 9 has a surface 18 having a normal line in the protruding direction of the first shaft portion 13 around the recess 17 at a position adjacent to the root portion of the first shaft portion 13. On the other hand, as shown in FIG. 5, the base member 2 is connected to the end surface of the lower surface support portion 32 facing the second bearing portion 36 and protrudes from the end surface to the second bearing portion 36 side. It has a convex portion 40 (see also FIG. 6).

  When the bell crank portion 9 is at the rotation angle in use, the surface 18 and the tip surface 41 of the convex portion 40 are in a state where the shaft portions 13 and 14 are inserted into the through holes 31 and 37. The positional relationship is opposite. Therefore, when the bell crank portion 9 is to be moved in the direction in which the second shaft portion 14 is removed from the through hole 37, the surface 18 and the tip surface 41 come into contact with each other, and the movement of the bell crank portion 9 is caused by the contact. Is regulated. That is, the convex part 40 and the surface 18 function as a restricting part that restricts the movement of the bell crank part 9. Further, since the intermediate shaft portion 15 is formed to have a larger diameter than the through hole 37, the movement of the bell crank portion 9 in the direction in which the first shaft portion 13 is removed from the through hole 31 is also restricted. Thus, when the bell crank portion 9 is at the rotation angle in use due to the surface 18, the convex portion 40, the intermediate shaft portion 15, and the through hole 37, the shaft portions 13 and 14 are detached from the through holes 31 and 37. A retaining structure for avoiding the above is configured.

  On the other hand, as shown by a dotted line 203 in FIG. 7, when the bell crank portion 9 is assembled to the base member 2, the bell crank portion 9 is set to a rotation angle different from the rotation angle in use. When the bell crank portion 9 is in the assembling state rotated at this assembling angle, the concave portion 17 and the convex portion 40 face each other on the movement path of the bell crank portion 9 in the direction of the axis L2. Positional relationship. Therefore, the movement of the bell crank portion 9 in the direction of the axis L2 between the state where the concave portion 17 and the convex portion 40 are fitted (fitted state) and the state where the fitting is released (released state). It becomes possible.

  Specifically, when the bell crank portion 9 is at the rotational angle in the assembled state and is in a released state in which the fitting between the concave portion 17 and the convex portion 40 is released, the bell crank portion 9 is 13 and 14 are arranged at the first positions inserted into the through holes 31 and 37. Further, when the bell crank portion 9 is at the rotation angle in the assembled state and the concave portion 17 and the convex portion 40 are in the fitted state, the bell crank portion 9 has the first shaft portion 13 inserted into the through hole 31. Then, the second shaft portion 14 is disposed at the second position away from the through hole 37. As described above, when the bell crank portion 9 is at the rotation angle in the assembled state, the bell crank portion 9 can be moved between the first position and the second position. In addition, the recessed part 17, the surface 18, and the convex part 40 correspond to the fitting structure of this invention. In the state where the bell crank portion 9 is disposed at the second position, it is assumed that the bell crank portion 9 is in an inclined state in which the axis L1 of the shaft portions 13 and 14 and the axis L2 of the through holes 31 and 37 coincide with each other. It is said. That is, the state in which the first shaft portion 13 is inserted into the through hole 31 and the second shaft portion 14 is disengaged from the through hole 37 when the bell crank portion 9 is in an inclined state in which the axes L1 and L2 do not coincide is the second state. It is not included in the position.

  Further, when the concave portion 17 and the convex portion 40 are in the fitted state, that is, when the bell crank portion 9 is in the second position in the assembled state, the side surface 42 (see FIG. 5) of the convex portion 40 and the concave portion 17 are provided. The rotation of the bell crank portion 9 is restricted by contact with the side surface 17a (see FIG. 4). Accordingly, it is possible to avoid the bell crank portion 9 being set to the rotation angle at the time of use while only the first shaft portion 13 is inserted into the through hole 31.

  In the above description, “when the bell crank portion 9 is at the rotation angle in the assembled state” is described. However, in the completed state in which all the parts of the vehicle door handle device 1 are assembled, The part 9 can be rotated between the positions 201 and 202 in FIG. 7 and cannot be freely rotated up to the rotation angle in the assembled state. That is, in the completed state of the vehicle door handle device 1, the bell crank portion 9 is restricted from rotating to the angle in the assembled state by the handle member 3 and the base member 2.

  Next, a method for assembling the vehicle door handle device 1 (particularly a method for assembling the bell crank portion 9 to the base member 2) will be described. First, the counterweight portion 20 and the torsion coil spring 51 are mounted on the shaft portion 12 (intermediate shaft portion 15) of the bell crank portion 9.

  Next, the bell crank portion 9 is assembled to the base member 2 in a state where the counterweight portion 20 and the torsion coil spring 51 are mounted. Specifically, first, as shown in FIG. 8, the shaft portion 12 of the bell crank portion 9 is inclined obliquely with respect to the axis L2 of the through hole 31, and the rotation angle during assembly shown by the dotted line 203 in FIG. In this state, the first shaft portion 13 is inserted into the through hole 31 (between the lower surface support portion 32 and the upper surface support portion 33) of the first bearing portion 30. Thereafter, the axis L1 of the shaft portion 12 is aligned with the axis L2 of the through holes 31 and 37, in other words, the second shaft portion 14 faces the through hole 37 of the second bearing portion 36. The bell crank portion 9 is rotated in the direction of arrow P in FIG. 9 with the first shaft portion 13 as a fulcrum while keeping the rotation angle and with the first shaft portion 13 inserted into the through hole 31 (see FIG. 9). At this time, since the concave portion 17 and the convex portion 40 are in the fitted state, only the first shaft portion 13 is inserted into the through hole 31 (second state). In addition, even if it is going to insert in the through-hole 31 of the 1st axial part 13 at the rotation angle other than the rotation angle at the time of an assembly | attachment, and to rotate to return to the horizontal after the insertion, Interference with the surface 18 prevents the insertion and rotation.

  Thereafter, as shown in FIG. 10, the bell crank portion 9 is horizontally moved (slid) in the direction of the through hole 37 (the direction of the arrow Q in FIG. 10) while maintaining the rotation angle at the time of assembling. The shaft portion 14 is inserted into the through hole 37. At this time, the fitting between the concave portion 17 and the convex portion 40 is released. Then, the bell crank part 9 is rotated to the angle at the time of use. At this time, the convex portion 40 and the concave portion 17 are shifted from the facing position in the rotation direction of the shaft portion 12, so that the convex portion 40 and the surface 18 around the concave portion 17 face each other. When the convex portions 40 and the surface 18 are in contact with each other, the movement of the bell crank portion 9 in the direction in which the second shaft portion 14 is detached from the through hole 37 is restricted. Thereafter, one extended end of the torsion coil spring 51 is hooked at a predetermined position of the base member 2. Thus, the assembly of the bell crank portion 9 to the base member 2 is completed.

  Thereafter, the assembly of the vehicle door handle device 1 is completed through processes such as assembling the handle member 3 to the base member 2 on which the bell crank portion 9, the counterweight portion 20, and the torsion coil spring 51 have been assembled. .

  Hereinafter, the effect of this embodiment will be described. According to the present embodiment, the pair of shaft portions 13 and 14 are formed integrally with the bell crank portion 9, and these shaft portions 13 and 14 are rotatably supported by the base member 2, so that no separate shaft is provided. However, the bell crank portion 9 can be rotatably supported. Therefore, the number of parts can be reduced.

  Further, in the present embodiment, the through holes 31 and 37 are formed in a perfect circle shape in a front view, and the shaft portions 13 and 14 are also formed in a perfect circular shape. 14 and the through holes 31, 37 can be prevented from rattling.

  Further, since the lower surface support portion 32 and the upper surface support portion 33 in the first bearing portion 30 are displaced in the direction of the axis L2 of the through hole 31, the first shaft portion 13 is inserted into the through hole with the bell crank portion 9 being inclined. 31 can be inserted. By making the bell crank portion 9 oblique, it is possible to avoid the second shaft portion 14 from interfering with the second bearing portion 36 when the first shaft portion 13 is inserted into the through hole 31.

  In the present embodiment, the bell crank portion 9 is moved in the axial direction by the convex portion 40 of the bell crank portion 9 and the surface 18 of the base member 2 at the rotation angle when the bell crank portion 9 is used. Since it is regulated, it is possible to avoid the bell crank portion 9 from falling off the base member 2.

  In addition, this invention is not limited to the said embodiment, A various change is possible to the limit which does not deviate from description of a claim. For example, in the above-described embodiment, the example in which the present invention is applied to the support structure of the bell crank portion has been described. However, the present invention may be applied to other components that are rotatably supported. Specifically, for example, the present invention may be applied to a handle member. It is preferable to apply the present invention to a handle member of a type that supports both ends in the longitudinal direction of the handle member rotatably like the handle member of Patent Document 1.

  In the above embodiment, the pair of shaft portions are formed in the bell crank portion and the pair of bearing portions are formed in the base member. Conversely, the pair of shaft portions are formed in the base member, and the pair of bearings The part may be formed in a bell crank part.
