In the present embodiment, as shown in FIG. 2, in the lens 14A, the object side portion in the outer peripheral surface of the lens 14A is provided with a waterproof portion which is formed to have a smaller diameter than the image side portion. The component arranging unit 141A arranges the 〇-shaped ring of the waterproof member 15A in the waterproof member arranging portion 141A to prevent the detachment of the 0-ring 15A. 2 to 5 are views showing a lens assembly according to an embodiment of the present invention. In addition to the configuration of the lens frame ι, the configuration of the lens 14A, and the configuration of the 〇-ring 15A in FIG. 2, the lens assembly 1A having the same configuration as that of FIG. 1 is shown in FIG. The lens assembly after 15A [the M356937 state of eight] is shown in Fig. 3 as an enlarged view of the portion of the 〇-shaped ring in which Fig. 2 is attached. In addition, FIG. 4 shows a state in which the lens assembly 1 is mounted after the 〇-ring 15 is mounted and after the pressure-bonding process is performed, and FIG. 5 shows a portion in which the 0-ring of the lens assembly of FIG. 4 is attached. Enlarged image. In Fig. 1, when the lens frame 1 is loaded into the lens 14, the waterproof member disposing portion 41 is provided first in the lens frame 4, but in the configuration shown in Fig. 2, in the first lens The object side portion in the outer peripheral surface is provided with a waterproof member arranging portion 141A having a diameter smaller than that of the image forming side portion, and the dam type ring 15A of the waterproof member is disposed in the waterproof member arranging portion 141A. For this reason, it is possible to load the lens ring 10 while pressing the 0-ring 15A with a hand or the like, and it is possible to obtain an effect of easily loading the 〇-shaped ring 15A. Moreover, as shown in Figs. 2 and 3 It is also possible to obtain an effect of visually confirming the loading state of the ring type i5A from the outside. On the other hand, after the 〇-shaped ring 15A is inserted, as shown in Fig. 4, the object-side opening frame ι〇ιA which forms the object-side opening of the lens frame 10 of the above I5 is crimp-processed into a full-circumference range on the object side opening. Press the object side of the 丨-type ring 丨 5 A. In this case, as shown in Fig. 5, the 〇-shaped ring 15A is deformed to be more suitable for the shape of the space between the object-side opening frame 1 〇丨A and the lens outer peripheral surface 丨4丨A of the lens frame i〇a. Waterproof performance. Here, in the above-described press-bonding process, thermocompression bonding or ultrasonic pressure bonding may be employed. An elastic member such as ethylene propylene rubber or enamel rubber is used for the 〇-shaped ring 15A. For the material of the lens frame, it is possible to use pA (polyamide) oxime, PPA (polyphthalamide), pps (polyphenylene sulfide), etc. for lens frames made of k materials. As a waterproof part, the M356937' can also be combined with 1*01^ (polyoxymethylene), PE (ψr榼, J t<private ethylene), PP (polypropylene), PC port (polycarbonate_), A molding port of a low melting point material such as LCP (liquid crystal polymer). As described above, when the material of the waterproof member is lower than the lens frame, the molded article is appropriately deformed when the thermocompression bonding is performed, and the object-side opening frame is spliced, whereby the waterproof performance is increased. The above description realizes a lens assembly in which the components are in the lens frame. Here, the shape of the ring arrangement portion 141A in which the O-ring 15A is disposed can also obtain a corresponding effect even if it is the shape of Fig. 1. Fig. 6 is a view corresponding to Fig. 3 and showing an embodiment of a different shape of the 〇-ring arrangement portion 141A shown in Fig. 3. As the 〇-shaped ring arranging portion 141β shown in Fig. 6(a), the corner portion of the 〇-shaped ring arranging portion (4) shown in Fig. 3 can be formed into a circular shape (10), and the type 0 can be easily caught.

Further, as the I5 〇-shaped ring arranging portion 141C shown in Fig. 6(b), a conical shape is slightly given to widen one side where the 〇-shaped ring 15 is disposed, and the 〇-shaped ring 15A can also be caught. The one side 142C is also slightly provided with a conical shape, and the Ο-shaped ring 15A is easily disposed from the outside, and the front end portion of the lens 14A may be rounded (chamfered) and the portion to be rounded may be the arranging portion 141D. 20 In any case, through the crimping process, the 〇-shaped ring 15 5 a of the waterproof member is just as suitable as shown in Fig. 5, so that the corresponding effect can be obtained. Finally, an example in which the lens assembly ία shown in Fig. 4 is applied to a camera mounted on a car will be described. Fig. 7 is a view showing a camera unit 2 M356937 including the lens assembly shown in Fig. 4 . In Fig. 7, there is no cross section of the camera unit 2 that is cut along the optical axis. The camera unit 2 shown in Fig. 7 is provided with the lens assembly 1A of Fig. 4, the camera body frame 20, and the imaging element 21. The imaging element 21 is mounted on the substrate 21, and is bonded and fixed to the camera body frame 2''. In the lens assembly 10 of the lens assembly IA of FIG. 4, the outer peripheral surface of the lens frame 10 and the inner peripheral surface of the camera body frame 2 are respectively formed with threads. When the camera unit 2 is assembled, the lens assembly of FIG. 4 is first smashed. After the edge is inserted into the camera body frame 2, the lens assembly is affixed to the camera body frame 2〇. At this time, the water-repellent treatment is performed by applying an adhesive to the outer periphery of the lens frame (7) and the front end portion of the camera main body frame 20 so that the water does not enter the inside of the camera unit from the front end side. Further, the substrate 2A on which the imaging element 2 such as the ccd solid-state imaging device is mounted is bonded and fixed to the camera body frame 2''. The lens assembly ia of Fig. 4 can be assembled in the 15 camera unit 2 in this simple order.
