  For example, a vehicle door mirror device includes a drive mechanism (storage mechanism) (see, for example, Patent Document 1), and the drive mechanism includes a stand. The stand is fixed to the vehicle body side, and a support shaft is integrally provided on the stand.

  The drive mechanism includes a case member, and the case member is rotatably supported on the support shaft. The case member is connected to a mirror for visually confirming the rear of the vehicle through a stay or the like, and the case member basically rotates integrally with the mirror.

  A motor base is fixed inside the case member, and a motor is fixed to the upper side of the motor base by a screw. The output shaft of the motor passes through the bottom wall of the motor base, and a worm gear is press-fitted into the output shaft below the motor base. The tip of the output shaft protrudes from the worm gear and is inserted into a bearing hole formed in the case member.

  Further, a helical gear is engaged with the worm gear, and when the helical gear is rotated by the rotation of the worm gear, a rotational force is applied to the support shaft, and the case member is rotated by a reaction force of the rotational force. Thus, the mirror is stored or erected.

However, in the vehicle door mirror device having the above-described configuration, as described above, the motor base to which the motor is fixed is fixed to the case member, and the tip end portion of the output shaft of the motor is supported by the case member. For this reason, there is a problem that a dimensional error or an assembly error between the motor base and the case member affects the axial accuracy of the output shaft, and the shaft shake occurs on the output shaft. Such shaft runout of the output shaft causes vibration hitting noise (noise / abnormal noise), and hinders the reduction of noise in the drive mechanism.

  The first stage gear may have a structure fixed to the output shaft of the motor, or a structure supported so as to be coaxial and rotatable relative to the output shaft of the motor (so-called “free fitting structure”). ]). As this loose fitting structure, the structure described in “Japanese Patent Application No. 2003-104982” already filed by the present applicant can be applied. This also applies to claims 2 and 3 below.

A vehicle mirror device according to a second aspect of the invention is a case member that is rotatably supported by a support shaft fixed to the vehicle body side and is directly or indirectly connected to a mirror for visually recognizing the rear of the vehicle.

Is pivotally supported. That is, since the output shaft of the motor is pivotally supported by the case member on both sides in the axial direction of the first gear, the output shaft is driven by the reaction force that acts on the first gear from the intermediate gear when the motor is driven (when the mirror rotates). It is possible to prevent or suppress the occurrence of shaft wobbling.

  Further, an intermediate gear meshed with the first gear is also supported by the case member. Therefore, it is possible to improve the axial accuracy (distance between the shafts and the axis of the shaft) between the first gear and the intermediate gear, and to ensure a good meshing state between the first gear and the intermediate gear. Thereby, it is possible to prevent the generation of abnormal noise (buzzing sound) due to the first stage gear receiving inflection (fluctuation due to radial force) from the intermediate gear.

Further, a first bearing portion is provided at the lower step portion of the bottom wall, and the tip end portion of the output shaft penetrating the first gear is pivotally supported. Thus, since the bottom wall of the case member is formed in a stepped shape, the first bearing portion and the second bearing portion are preferably arranged even if the motor is arranged in the vertical direction with respect to the case member. it can.

  The drive mechanism 20 includes a case member 28, and the case member 28 includes a main body 30 and a cover 32 that is detachably attached to the main body 30. As shown in FIG. 6, the bottom wall of the main body portion 30 is formed in a stepped shape having an upper step portion 34 and a lower step portion 36. A through hole 37 (see FIG. 4) is formed in the lower step portion 36, and the support shaft 26 is rotatably inserted. In addition, a cylindrical support portion 38 protrudes from the bottom wall of the cover 32, and the support portion 38 is rotatably fitted to the tip end of the support shaft portion 26. As a result, the case member 28 is rotatably supported by the support shaft 26.

  As shown in FIG. 7, a detent plate 40 is disposed between the lower step portion 36 of the main body 30 and the fixing portion 24 of the stand 22, and the rotation range of the case member 28 relative to the support shaft 26 is predetermined. The range is limited.

  On the other hand, a gear plate 42 as a final gear is disposed inside the main body 30. The gear plate 42 is supported coaxially and rotatably on the support shaft 26.

  Further, a torsion coil spring 48 is disposed between the tea washer 46 and the clutch disk 44. The torsion coil spring 48 urges the clutch disc 44 in the direction of engagement with the gear plate 42. As a result, the meshing engagement state between the gear plate 42 and the clutch disk 44 is normally maintained, and the relative rotation of the gear plate 42 with respect to the support shaft 26 is restricted.

  Further, as shown in FIG. 5, a worm shaft 50 as an intermediate gear is provided on the radial side of the gear plate 42. As shown in FIG. 6, the worm shaft 50 is disposed with its axis A intersecting the axis B of the support shaft 26, and the worm gear portion 52 and the helical gear portion 54 meshed with the gear plate 42 are integrally formed. Have. The worm shaft 50 is rotatable about its own axis by supporting both ends in the axial direction on the main body 30 via the metal collar 56.

  Above the worm shaft 50, a gear CP support 58 formed in a U-shape is disposed. The gear CP support 58 is in contact with the metal collar 56 at both ends on the opening side (see FIG. 4). Further, a main body portion 62 of the motor 60 is disposed above the gear CP support 58, and the main body portion 62 is in contact with the upper end portion of the gear CP support 58. The main body 62 is fixed to the upper stage 34 of the main body 30 of the case member 28 by a screw 64 (see FIG. 3), and the gear CP support 58 is a fastening force of the main body 62 to the main body 30 by the screw 64. Thus, as shown in FIG. 2, both end portions on the opening side are pressed against the metal collar 56 (see arrow D). This prevents the metal collar 56 (worm shaft 50) from being lifted.

  Further, the output shaft 66 of the motor 60 is arranged in a state where the axis C thereof is parallel to the axis B of the support shaft 26 (a state intersecting the axis A of the worm shaft 50), as shown in FIG. The main body 30 is accommodated in a housing hole 68 having a substantially circular cross section formed from the upper step 34 to the lower step 36.

  The accommodation hole 68 opens to the worm shaft 50 side, and a worm gear 70 as a first-stage gear press-fitted and fixed to the output shaft 66 is exposed to the worm shaft 50 side. The worm gear 70 is meshed with the helical gear portion 54 of the worm shaft 50.

  Further, as shown in FIG. 1, the distal end portion of the output shaft 66 penetrates the worm gear 70 and protrudes downward, and the shaft can be freely rotated in a bearing hole 72 as a first bearing portion formed in the lower step portion 36. It is supported.

  Further, a bearing member 74 constituting the case member 28 is provided between the worm gear 70 and the main body 62 of the motor 60. The bearing member 74 is formed in a cylindrical shape, and an intermediate portion of the output shaft 66 is rotatably fitted in a circular hole 75 formed in the shaft center portion. The bearing member 74 is attached to the main body 30 by fitting to the upper end side of the accommodation hole 68 and holding the outer periphery on the support shaft 26 side on an arc-shaped holding surface formed on the gear CP support 58. Thus, the intermediate portion of the output shaft 66 is pivotally supported on the main body 30 by the bearing member 74. The bearing member 74 is preferably formed of a material having a small sliding resistance with the worm gear 70.

  Next, the operation of the first embodiment will be described.

  In the door mirror device 10 configured as described above, the worm gear 70 and the worm shaft 50 (the worm gear portion 52 and the helical gear portion 54) are rotated by driving the motor 60, thereby being applied to the gear plate 42 of the support shaft 26. The case member 28 is rotated by the reaction force of the rotational force. For this reason, the mirror 16 is rotated integrally with the visor 14 and the case member 28 and stored or erected.

  Here, in the door mirror device 10 according to the first embodiment, the motor 60 is fixed to the main body 30 of the case member 28, and the output shaft 66 of the motor 60 has a tip portion that penetrates the worm gear 70. The intermediate portion between the worm gear 70 and the main body portion 62 of the motor 60 is supported by the main body portion 30 of the case member 28 via the bearing member 74. ing.

  Thus, since the output shaft 66 is pivotally supported by the main body portion 30 of the case member 28 to which the main body portion 62 of the motor 60 is fixed, it is possible to easily ensure the axial accuracy of the output shaft 66. Thereby, it is possible to prevent or suppress the occurrence of shaft runout in the output shaft 66.

  By the way, in the drive mechanism of the conventional vehicle door mirror device, the output shaft of the motor has a configuration (cantilever structure) in which only the tip portion (one end side in the axial direction of the worm gear) is pivotally supported. There is a problem that the output shaft is shaken by the reaction force.

  In this respect, in the door mirror device 10 according to the first embodiment, as described above, the output shaft 66 of the motor 60 is pivotally supported by the case member 28 on both sides in the axial direction of the worm gear 70, so that the motor 60 is driven. The reaction force (see arrow E in FIG. 1) acting on the worm gear 70 from the worm shaft 50 (helical gear portion 54) at the time of turning the mirror can be received on both sides in the axial direction of the worm gear 70 (arrows in FIG. 1). Thus, it is possible to prevent or suppress the occurrence of shaft shake in the output shaft 66. Therefore, generation of vibration hitting sound due to shaft runout of the output shaft 66 is prevented or suppressed, and noise reduction of the drive device 20 is realized.

  FIG. 10 is a diagram showing the relationship between the noise level and the frequency of the operating sound in the conventional door mirror device (door mirror device whose motor output shaft is cantilevered) and the door mirror device 10 according to the first embodiment. Is shown.

  As can be seen from FIG. 10, in the door mirror device 10, the sound pressure of all frequency components is significantly reduced and the operating noise is reduced by about 30% compared to the conventional door mirror device.

  Further, in the door mirror device 10 according to the first embodiment, each gear (worm gear 70, worm shaft 50, gear plate 42) is attached on the basis of the main body 30 of the case member 28 (all gears). Are integrated into one part of the main body 30), the shaft accuracy (distance between shafts, shaft center) of each gear is improved, and the worm shaft 50 (second stage gear) and subsequent inflections (by radial force) Fluctuation) and no abnormal noise (growing sound) is generated.

  FIG. 11 is a diagram showing the relationship between noise and time during operation of a conventional door mirror device (a door mirror device whose motor output shaft is cantilevered). The relationship between abnormal noise and time during operation of the door mirror device 10 according to one embodiment is shown in a diagram.

  From FIG. 11, it can be seen that the conventional door mirror device generates abnormal noise (growing sound) (see the wavy line in FIG. 11). This is because the first gear (worm gear) receives inflection (fluctuation) from the second gear (worm shaft). On the other hand, as shown in FIG. 12, in the door mirror device 10, each gear is integrated into one part of the main body 30, and the output shaft 66 is pivotally supported at both ends in the axial direction of the worm gear 70. It can be seen that no abnormal noise occurs.

  Furthermore, in the door mirror device 10 according to the first embodiment, the configuration as described above reduces the load power of the motor 60 by about 10% and reduces the variation in operating noise by about 50%, for example.

  Furthermore, in the door mirror device 10 according to the first embodiment, each component is assembled with the main body 30 of the case member 28 as a reference. For example, the number of parts is about 20% and the weight is about 20%. The number of assembly steps can be reduced by about 10%.

  Further, in the door mirror device 10 according to the first embodiment, all the parts other than the parts supported by the stand 22 can be assembled in one direction from directly above with respect to the main body 30 of the case member 28. The productivity is good and the productivity is greatly improved.

  In addition, in the door mirror device 10 according to the first embodiment, since the bottom wall of the case member 28 (main body portion 30) is formed in a stepped shape, the motor 60 extends in the vertical direction with respect to the case member 28. Even if it arrange | positions, the bearing hole 72 (1st bearing part) and the bearing member 74 (2nd bearing part) can be arrange | positioned suitably.

  As described above, the door mirror device 10 according to the first embodiment of the present invention can prevent or suppress the shake of the output shaft 66 of the motor 60.

The door mirror device 10 according to the first embodiment has a structure in which the worm gear 70 as the first-stage gear is press-fitted and fixed to the output shaft 66 of the motor 60. However, the present invention is not limited to this, and the first-stage gear is the output of the motor. A structure that is coaxial with the shaft and supported so as to be relatively rotatable by a predetermined angle (so-called “free fitting structure”) may be employed. As this loose fitting structure, the structure described in “Japanese Patent Application No. 2003-104982” already filed by the present applicant can be applied. Thus, when the output shaft of the motor and the first-stage gear have a loose fitting structure, it is possible to more effectively suppress the shake of the output shaft.
