Abstract
A balancer device includes a housing including a tubular body section and also including a front end plate and a rear end plate that block opposite ends of the body section in a direction of an axis; a rod that extends through the front end plate in a thickness direction thereof and that is supported such as to be movable in the direction of the axis; a movable member that is fixed to the rod and that is accommodated within the housing; a compression coil spring that is disposed between the movable member and the rear end plate; and a coupling member that couples the rod and the rear end plate to each other with play that is larger than a stroke of the rod in the direction of the axis.
Claims11
A balancer device comprising:
- a housing including a tubular body section and also including a front end plate and a rear end plate that block opposite ends of the body section in an axial direction;
- a rod that extends through the front end plate in a thickness direction thereof and that is supported such as to be movable in the axial direction;
- a movable member that is fixed to the rod and that is accommodated within the housing;
- a compression coil spring that is disposed between the movable member and the rear end plate;
- and
- a coupling member that couples the rod and the rear end plate to each other with play that is larger than a stroke of the rod in the axial direction,
- wherein the coupling member includes a first member fixed to the rear end plate and a second member fixed to the rod, and
- wherein the second member includes an abutment surface that abuts onto the first member from the rear end plate at a point in time when the play is lost.
A balancer device comprising:

- a rod that extends through the front end plate in a thickness direction thereof and that is supported such as to be movable in the axial direction;
- a movable member that is fixed to the rod and that is accommodated within the housing;
- a compression coil spring that is disposed between the movable member and the rear end plate;
- and
- a coupling member that couples the rod and the rear end plate to each other with play that is larger than a stroke of the rod in the axial direction,
- wherein the coupling member is a flexible wiring member one end of which is fixed to the movable member and another end of which is fixed to the rear end plate in a state where the wiring member extends loosely.
