Clutch operating apparatus

A clutch operating apparatus comprising:

• a control valve for controlling pressure oil to connect and disconnect a clutch;
• a clutch pedal supported to be pivotable;
• a bracket pivotable with said clutch pedal;
• an interlocking mechanism including an interlocking member for operatively interconnecting said bracket and said control valve to operate said control valve with a pivotal movement of said clutch pedal;
• and
• a coupling mechanism for coupling said bracket to one end of said interlocking member, said coupling mechanism including:
• a connecting pin disposed on one of said bracket and said interlocking member;
• and
• receiving bores formed in the other of said bracket and said interlocking member for receiving said connecting pin, said receiving bores being in the form of slots shaped such that said clutch pedal has a lost motion only in an initial pivotal displacement thereof not to transmit the pivotal displacement to said control valve,
• wherein said interlocking member has a spring for acting to oppose a sideways force applied to said interlocking member in time of transmitting an operational displacement.

• wherein said interlocking mechanism is coupled to a spool of said control valve for transmitting an operational displacement thereto through a lever pivotable about a first axis, and
• said interlocking mechanism includes a relay mechanism pivotable about a second axis parallel to said first axis to transmit the operational displacement.
