NEUTRAL RETURN MECHANISM
A neutral return mechanism (26) includes an interlocking shaft (31) to be pushed and pulled in an axial direction (D3) in conjunction with a swinging operation of an operation member (80); a housing member (32) to support the interlocking shaft (31) such that the interlocking shaft (31) is movable in the axial direction and accommodate the interlocking shaft (31) such that one of opposite end portions thereof protrudes; a neutral return spring (33) to return the interlocking shaft (31) from a post-movement position (P5, P6) to an initial position (P4), the post-movement position (P5, P6) being a position to which the interlocking shaft (31) has been moved by operation of the operation member (80), the initial position (P4) being a position in which the interlocking shaft (31) was located before the operation of the operation member (80), the neutral return spring (33) being accommodated in the housing member (32) such that it extends in the axial direction (D3) of the interlocking shaft (31), wherein the housing member (32) includes a supported portion (39) between a spring accommodation portion (40) in which the neutral return spring (33) is accommodated and a protrusion opening (48) through which the interlocking shaft (31) protrudes, the supported portion being supported at a bracket member (53).
