1. A working-tool (17) orienting device in a tire demounting machine (1) comprising:
a base (2) supporting a rotatable apparatus (4) around a rotation axis (Z), the base being configured to rest and block thereon rims (R1, R2, R3) of wheels of vehicles; a column (3) extending from said base (2) and having one fastening end (103) to said base and one opposite end (203) facing upward, a column longitudinal axis being defined between said fastening end and said opposite end; one arm (11) transversally supported on said opposite end (203) of said column (3), the arm being movable at a distal (211) end from said column (3), with respect to said rotatable apparatus (4), between a working position and a resting position; a supporting arrangement (13, 14, 16) of said working-tool (17) associated to said distal end (211); a joining system (12; 18, 21; 412) interposed between said supporting arrangement (13, 14, 16) and said distal end (211), the joining system (12; 18, 21; 412) being configured to make said supporting arrangement (13, 14, 16) movable with respect to said arm (11); and a connecting member (22; 301, 310, 317, 121, 502, 509, 510) interposed between said joining system (12) and said column (3) and movable together with said arm (11), the connecting member being configured to make said joining system (12) rotate with respect of said arm (11), such to maintain said working-tool (17) substantially constantly oriented in said working position with respect of said rims (R1, R2, R3) during rotation movements of said arm (11) with respect of said column (3).
