Problems solved by technology

[0006] In Patent Document 1, since the first annular tooth row and the second annular tooth row are exposed to the outside, they are easily deteriorated and damaged during use, and the durability of the angle fixing device is low.
[0007] Particularly, when the first annular dentition and the second annular dentition exposed to the outside are formed of synthetic resin, the synthetic resin is easily affected by external ultraviolet rays, oil, etc., so the first annular dentition and the second annular dentition are formed of synthetic resin. The durability of the second annular tooth row, and thus the durability of the angle fixation device, is further reduced
[0008] In addition, the same problem exists in the lighting unit

Abstract

Disclosed is an angle setting device (4) having a first member (21) and a second member (22), which are coupled in a coupling direction (D1) parallel to a predetermined axis (C1), an annular seal (23) which defines a sealed space (24) between the first member (21) and the second member (22), and fastening members (25) which fasten the first member (21) with the second member (22) on the outer side of the annular seal (23) in the radial direction. The first member (21) is comprised of a first annular teeth row (27). The second member (22) is comprised of a second annular teeth row (28) which meshes with the first annular teeth row (27). The first annular teeth row (27) and the second annular teeth row (28) are annularly arranged about the predetermined axis (C1), and can be meshed at a predetermined rotational position in a circle about the predetermined axis (C1). The first annular teeth row (27) and the second annular teeth row (28) are arranged within the sealed space (24).

Description

technical field [0001] The present invention relates to an angle fixing device for fixing, for example, a signal indicator lamp, a lighting device, etc. in an adjustable manner. The present invention also relates to a signal display lamp unit and a lighting device unit comprising the above-mentioned angle fixing device. Background technique [0002] Signal indicator lamps are installed in automatic machines, production lines, parking lots, dangerous places, etc., and use the light emitted from the light source to signal various states such as material shortage, work jam, full parking, and danger. The signal display lamp unit has the above-mentioned signal display lamp and the above-mentioned angle fixing device for attaching the signal display lamp to an installation target, such as an automatic machine. [0003] The angle fixing device of Patent Document 1 has a first member fixed to a robot or the like, and a second member fixed to a signal indicator lamp. The first part...
