Operation device

An operation device, comprising:

• a support member;
• and
• an operation member supported by the support member so as to be pivotable about a pivot axis,
• wherein:
• the operation member is manually pivotable between an initial position and an end position,
• one of the support member and the operation member has a first base and a shaft hole defined in the first base and extending in an axial direction that coincides with the pivot axis, the shaft hole having a circular cylindrical inner sliding surface that is concentric with the pivot axis,
• the other of the support member and the operation member has a second base and a shaft projecting from the second base and extending in the axial direction, the shaft having a circular cylindrical outer sliding surface that is concentric with the pivot axis,
• the first base and/or the second base is (are) elastically deformable in the axial direction so that the shaft can be inserted into the shaft hole,
• a first protrusion is formed on a distal end portion of the shaft and projects radially outward from the circular cylindrical outer sliding surface, and
• the first base includes:
• a first escape section recessed radially outward from the inner sliding surface, the first escape section being configured to allow the first protrusion to pass through the first base when the shaft is being inserted into the shaft hole with the operation member is located in the initial position;
• and
• a first slip-off preventing section disposed adjacent to the first escape section in a circumferential direction of the shaft hole, the first slip-off preventing section being configured to prevent the shaft from coming out of the shaft hole when the operation member is pivoted from the initial position to the end position;
• the shaft has a second inclined surface that is inclined so as to approach the second base in the axial direction while extending radially outward, and
• the second inclined surface is disposed on an opposite side of the first protrusion across the pivot axis.

An operation device comprising:

• and
• an operation member supported by the support member so as to be pivotable about a pivot axis,
• wherein:
• the operation member is manually pivotable between an initial position and an end position,

• the other of the support member and the operation member has a second base and a shaft projecting from the second base and extending in the axial direction, the shaft having a circular cylindrical outer sliding surface formed that is concentric with the pivot axis, and
• the first base and/or the second base is (are) elastically deformable in the axial direction so that the shaft can be inserted into the shaft hole,
• a second protrusion is formed at a position opposed to a root side of the shaft in the first base and project radially inward from the inner sliding surface, and
• the shaft includes:
• a second escape section recessed radially inward from the outer sliding surface, the second escape section being configured to allow the second protrusion to pass through the shaft when the shaft is being inserted into the shaft hole with the operation member is located in the initial position;
• and
• a second slip-off preventing section disposed adjacent to the second escape section in a circumferential direction of the shaft hole, the second slip-off preventing section being configured to prevent the shaft from coming out of the shaft hole when the operation member is pivoted from the initial position to the end position.
