To D-shaped etc. during observation, and output shaft 12A is formed as into corresponding shape with the part of hole portion 202A engagings, to realize tooth
Rotation stops of the 20A relative to output shaft 12A is taken turns, certainly, it is not limited to this, also rotation stop can be realized by bonding).It is also, defeated
Shaft 12A front end across C-shaped ring 50A insertions installation frame 30A support 32A opening portion 321A, and C-shaped ring 50A with
Opening portion 321A surrounds the whole side face of output shaft 12A front end together.Herein, except output shaft 12A is than above-mentioned embodiment 1
Motor body 10 output shaft 12 grow outside, motor body 10A is identical with the motor body 10 of above-mentioned embodiment 1, in addition,
Installation frame 30A structure is also identical with the installation frame 30 of above-mentioned embodiment 1, therefore, no longer to motor body 10A and peace
The frame 30A concrete structure of framing up is repeated.
According to present embodiment, the technique effect essentially identical with above-mentioned embodiment 1 can be played.
According to present embodiment, without significantly being changed to existing motor apparatus, as long as additional peace on its basis
Frame up frame, just gear can be avoided to cause output shaft in the radially motion of output shaft in the actual use of motor apparatus
Tilt.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that specific implementation of the invention is not by above-mentioned reality
Apply the limitation of mode.
For example, the motor apparatus of above-mentioned embodiment can be applied into projecting apparatus as shown in Figure 5, now, fill motor
The gear put engages with the lens barrel side gear of projecting apparatus, and thereby, motor apparatus rotates lens barrel by drive gear rotation,
Focusing of projecting apparatus etc. can be carried out.In which case it is convenient in a manner of opening portion is towards a side opening of lens barrel side gear
Motor apparatus is installed, thereby, can more reliably avoid radially motion of the gear in output shaft, improves the rotation essence of output shaft
Degree.
In addition, in the above-described embodiment, motor body is accommodated with rotor, stator and gear train in shell, rotor
Rotation is transferred to output shaft via gear train, but is not limited thereto, and the concrete structure of motor body can be appropriate as needed
Change.For example, motor body also may not include gear train, now, output shaft can be directly connected with the rotating shaft of rotor.
In addition, in the above-described embodiment, mounting plate portion is in substantially discoideus, and support is substantially in fan-shaped tabular, but simultaneously
This is not limited to, the shape of mounting plate portion and support can be appropriately arranged with as needed.For example, also support can be formed as big
Cause discoideus.
In addition, in the above-described embodiment, support 32 has opening portion 321, support 32A has opening portion 321A,
But it is not limited thereto, for example, as shown in Figure 3 A and Figure 3 B, the axis L directions along output shaft can be also set on support 32B
Through support 32B through hole 322B, to substitute above-mentioned opening portion 321,321A.Now, by by output shaft or axle portion for example
Insert through hole 322B across C-shaped ring 50B, can reliably avoid gear 20B because of the radially motion in output shaft and from output shaft
Come off.
In addition, in the above-described embodiment, axle portion 201 is embedded in opening portion 321, output shaft 12A front end across C-shaped ring 50
Across C-shaped ring 50A insertion installation frames 30A support 32A opening portion 321A, but it is not limited thereto, also can be by C-shaped ring
Configuration is configured to be connected to from support 32, the 32A side opposite with motor body 10,10A in outside, such as by C-shaped ring
Support 32,32A, C-shaped ring can be also configured between gear 20,20A and support 32,32A.Certainly, according to actual conditions,
C-shaped ring can also be omitted.
In addition, in the above-described embodiment, the paired locking tab as engaging portion, card are provided with mounting plate portion
Determine portion, the protuberance as engaging portion is provided with shell, but be not limited thereto, can also be set in mounting plate portion prominent
Go out portion, and be arranged on shell to locking tab.In addition, engaging portion and engaging portion are also not limited to locking tab and dashed forward
Go out portion, can be appropriately arranged with as needed.For example, can also projection and hole be used to be used as engaging portion and engaging portion.
In addition, in the above-described embodiment, engaging portion is provided with mounting plate portion, it is provided with shell engaged
Portion, installation frame is fixed on shell by the way that engaging portion and engaging portion are locking, but is not limited thereto, and installation frame is fixed
Can suitably it be set as needed in the mode of shell.For example, screw etc. can also be used is fixed on shell by installation frame, can also make
Installation frame is fixed on shell with bonding agent etc., certainly, as needed, can also be by above-mentioned locking strutcture, screw, bonding agent certainly
By combining.In addition, such as can also form engaging portion and/or engaging portion by resin, metal, now, can be by making resin
Melting engages engaging portion with engaging portion, or will be engaged engaging portion with engaging portion by welding.
