The present invention relates to a door mirror device having a storage mechanism. 2. Description of the Related Art In a part of a conventional door mirror device, a mirror frame (frame) in which an actuator for adjusting a mirror angle is mounted on a pivot shaft serving as a fulcrum of rotational movement for storing a mirror is known. Some are designed to be attached to The frame on which such an actuator is mounted is connected to the housing to form a mirror assembly. [0003] In addition, instead of such a frame type, there is one in which an actuator is directly mounted on a housing (Japanese Patent Laid-Open No. 7-1).
64969). In this case, a plurality of reinforcing ribs are provided on the rear surface side (inner surface side) of the housing in order to increase the rigidity of the actuator mounting portion in the housing. However, if such reinforcing ribs are provided, sink marks will occur on the surface side of the housing where the reinforcing ribs are provided. Since such sink marks are generated on the front surface side of the housing, there are problems such as poor appearance. In order to solve such a problem, instead of providing ribs or the like which are liable to cause sink marks, a frame which also serves as a reinforcing member is provided, thereby providing a housing and a door mirror device which improves the mounting rigidity of the whole. Is the object (problem) of the present invention. [0004] In order to solve the above problems, the present invention takes the following means. That is, in the present invention, a mirror, an actuator that drives the mirror, a housing that protects the mirror and the actuator, a frame that also serves as a reinforcing member that is the basis of the retracting movement of the mirror assembly including the housing, Regarding a door mirror device consisting of a pivot shaft serving as a base point for the storage movement of the frame and a base serving to fix the pivot shaft to the door side, the frame is coupled to the housing side,
Thereby, the frame so as to form a reinforcing member of the housing, further, the actuator, as well as to attach the housing side, which is reinforced by the frame, the actuator and frame
And the upper part of the

A configuration is adopted in which the surface is provided at a portion where the surface is changed, which is a connection portion with the wall portion . [0005] By adopting such a structure, the to exhibit the following effects in those of the present invention. That is, the housing is connected to the frame forming the reinforcing member, and the actuator is mounted at the housing which is the member having such a reinforcement. In some cases, the housing does not cause chatter vibration or the like. That is, since the housing to which the actuator is attached is reinforced by the frame having high rigidity, the portion to which the actuator is attached has high rigidity. Then, since the actuator is attached to the place where the rigidity is increased, the vibration from the actuator is not transmitted to the housing or the like. Further, as described above, the housing to which the actuator is mounted is entirely reinforced by the frame, so that the housing itself can be made thinner, and the weight of the housing can be reduced, and the door mirror device of the present invention can be further reduced. The overall weight can be reduced. According to the present invention, the appearance of the surface of the housing can be improved.
Become like Generally, when this housing is formed of a plastic material, the back side (inner side) of the housing is used.
, A reinforcing rib or the like is provided at a connection portion with the frame or the like. Then, sinkage occurs on the opposite side (front side) of the portion where the reinforcing ribs and the like are provided. The sink marks may cause the most noticeable appearance of the housing surface to deteriorate. On the other hand, in the case of the present invention, not only the above-described reinforcing rib is not provided but also the mounting boss portion to which the actuator or the like is mounted changes on the surface which is the connecting portion between the bottom surface portion of the housing and the peripheral side wall portion. However, even if some sink marks occur, the sink marks on the surface become less noticeable because the surface is a change part. Therefore, according to the present invention, the overall appearance of the housing surface portion which is most noticeable can be improved. An embodiment of the present invention will be described with reference to FIGS. 1 and 2. Although it relates to the present embodiment, as shown in FIG. 1, the structure is such that the actuator 3 for adjusting the angle of the mirror 4, the actuator 3 and the mirror 4 are housed, and the protection of the actuator 3, the mirror 4, and the like. A housing 1 to be provided, a frame 2 which serves as a reinforcement of the housing 1 and supports a storage movement of a mirror assembly including the housing 1 and the actuator 3 and the like; and a pivot which is a base point of the storage movement of the mirror assembly It is basically composed of a pivot shaft 5 forming a part, and a base 6 serving to attach the mirror assembly to a door via the pivot shaft 5. In the housing having such a basic configuration, the housing 1 is entirely formed in a vessel-like form, and is integrally formed of a plastic material. As shown in FIG. 2, the housing 1 has a bottom surface 11 that forms the bottom of the vessel, and is formed continuously with the bottom surface 11. And a peripheral side wall portion 19 forming the same. The bottom portion 11 and the peripheral side wall portion 19 are each formed of a specific surface, and these two surfaces are connected by coupling portions 111, 111 'and the like. Further, the actuator 3 or the frame 2 is attached (for coupling) to the coupling portions 111, 111 ', which are coupling portions of these surfaces, or a peripheral portion thereof.
The mounting bosses 12 and 13 are provided. And these mounting bosses 12, 13,
In addition, the bottom surface 11 and the peripheral side wall 19 are integrally formed by injection molding means or the like. Next, the mounting boss 12 of the housing 1
As shown in FIG. 1, the frame 2 attached to the housing 1 has a reinforcement portion 21 which forms a reinforcing member of the housing 1.
And a pivot portion 25 for supporting the retracting movement of the mirror assembly including the housing 1 and the actuator 3 attached to the housing 1 and the like. When the pivot portion 25 of the frame 2 having such a configuration is fitted into the pivot shaft 5, the retracting movement of the mirror assembly is performed with respect to the pivot shaft 5. It is. As shown in FIG. 1, the pivot shaft 5, which is the starting point of such a retracting movement, is attached to a base 6, and the base 6 is attached (fixed) to the door, whereby the door of the mirror device is opened. It is designed to be attached to In the structure having such a configuration, the mounting boss 13 of the housing 1 is
An actuator 3 for adjusting the angle of the mirror is directly mounted. The mirror 4 is attached to such an actuator 3, and the main components such as the mirror 4 and the actuator 3 are housed in the housing 1 and protected. Next, the operation and the like of the embodiment having the above-described configuration will be described.
First, as shown in FIG. 2, the housing 1 is a member in which the reinforcement portion 21 of the frame 2 serving as a reinforcing member is coupled to the mounting boss portion 12 thereof, and such a reinforcement is provided. Since the actuator 3 is attached to the housing 1, the housing 1 does not generate chatter vibration or the like when the actuator 3 for adjusting the mirror angle is operated. That is, since the housing 1 is reinforced by the light and highly rigid frame 2, the portion to which the actuator 3 is attached has high rigidity.
Then, since the actuator 3 is attached to the place where the rigidity is increased, the vibration from the actuator 3 is not transmitted to the housing 1. In addition, since the housing 1 to which the actuator 3 is attached is entirely reinforced by the frame 2, the thickness of the housing 1 itself can be reduced. Weight saving,
As a result, the weight of the entire door mirror device can be reduced. Also, as shown in FIG.
And mounting bosses 12 and 13 provided on the housing 1 side of the frame 2 to form a mounting portion of the frame 2 with the bottom surface 11 of the housing 1 and a peripheral side wall 19 forming a mirror visor. Connection part 11

That is, the reinforcing ribs in the conventional one are abolished, and the mounting bosses 12 and 13 are connected to the connecting portion 11 having a changed surface.
1, 111 ', so that sinks and the like during injection molding are less likely to occur as a whole. Also, even if a slight sink mark or the like occurs in this portion, the portion becomes less noticeable and does not impair the appearance of the housing 1. According to the present invention, a mirror, an actuator for driving the mirror, a housing for protecting the mirror and the actuator, and a retracting movement of the mirror assembly including the housing are provided. With respect to a door mirror device including a frame, a pivot shaft serving as a base point of the storage movement of the frame, and a base serving to fix the pivot shaft to the door side, the frame is coupled to the housing side, thereby The frame is formed as a reinforcing member of the housing, and the actuator is mounted on the side of the housing reinforced by the frame. Therefore, the housing is connected to the frame forming the reinforcing member. As well as such reinforcement The actuator is attached to the housing, which is a formed member, so that the housing does not generate chatter vibration or the like when the actuator for adjusting the mirror angle is operated. That is, since the housing is reinforced by a light and rigid frame, the portion to which the actuator is attached has high rigidity, and the actuator is attached to such a location where the rigidity is increased. Vibration from the actuator is not transmitted to the housing. Further, since the housing on which the actuator is mounted is entirely reinforced by the frame, the thickness of the housing itself can be reduced.
Consequently, the weight of the entire door mirror device can be reduced. [0014] Further, an attachment boss provided on the housing side of the actuator and the frame for attaching the actuator and the frame to the housing is connected to a bottom wall of the housing and a peripheral side wall forming a mirror visor. Since a configuration is provided in which the surface of the housing changes, the sink can be prevented from being formed on the surface of the housing. That is, the reinforcing ribs in the conventional one are abolished, and the mounting boss portion is provided in the joint portion where the surface changes, so that sinks and the like during injection molding are less likely to occur as a whole. Also, even if a slight sink mark or the like occurs in this portion, the portion becomes less noticeable, and the appearance of the housing can be improved.
