Abstract (en)
[origin: JP2017106905A] PROBLEM TO BE SOLVED: To simplify assembly or disassembly of a balance spring stud.SOLUTION: A holding or supporting assembly includes: a spring stud 5; and a stud holder 3 configured to be mounted on a balance cock 2. The stud holder 3 includes a base 30 having at least one annular part. This base includes a first projection 32 and a second projection 35 extending to the radial direction respectively in an annular part. One projection from among the projections includes an elastic arm 33 extending in a direction parallel to the base from the projection to the other projection. The elastic arm 33 forms, together with the base, a housing 34 for storing a balance spring stud 5. The first and second projections 32 and 35 are capable of allowing the balance spring stud 5 to give stresses (P and P') to the elastic arm 33 by cooperating with a tool. As a result, the elastic arm 33 is deformed so that the balance spring stud 5 can be assembled or disassembled.SELECTED DRAWING: Figure 1
