CHUTE SWIVEL-REGULATION MECHANISM

摘要

A chute swing restricting mechanism for locking a chute supported by a rotary shaft being rotatably arranged on a vehicle body of a concrete mixer truck in a storage position includes an engagement part which is rotatable along with the rotary shaft and has an engagement hole, a swing restricting pin which is movably installed relative to the vehicle body, and an energizing member for energizing the swing restricting pin. The swing restricting pin is configured to be inserted into the engagement hole of the engagement part according to an energizing force of the energizing member when the chute is swung and reaches the storage position.
