Document Type and Number:
WIPO Patent Application WO/2020/255615
Kind Code:
A1
Abstract:
This retroreflection device (100) comprises: a prism assembly, a set of a first member (110) and second member (120), a fixing part (200), a first hole part, a second hole part, a shaft part (140), a holding mechanism (150), and a rotation impeding mechanism (160). The prism assembly comprises a plurality of corner cube prisms (131). The set of the first member (110) and second member (120) hold the prism assembly by sandwiching the same. The fixing part (200) is provided to the first member (110) and second member (120) and prevents the positional deviation of the prism assembly. The first hole part is formed in the first member (110). The second hole part is formed in the second member (120). The shaft part (140) is inserted into the first hole part and second hole part. The holding mechanism (150) maintains a state in which the first member (110) and second member (120) hold the prism assembly by sandwiching the same. The rotation impeding mechanism (160) impedes the relative rotation of the first member (110) and second member (120) around the shaft part (140).
